Finger-safe power distribution blocksCatalog symbol:• PDBFS_Description:The small footprint, high Short-Circuit Current (SCCR) Bussmann™ series power distribution blocks provide IP20* finger-safe protection under specified conditions. These UL® Listed, single-pole blocks are of a modular design that permits dovetailing together the required number of poles for an application and still meet the UL 1953 minimum 1” and 2” spacing required per UL 508A for feeder circuit applications and per NEC® for field installations.With SCCRs up to 200 kA, these blocks help achieve compliance with National Electrical Code (NEC) and OSHA requirements by resolving a common SCCR “weak link” in industrial control panels.To increase application flexibility, these blocks feature dual-wire rated ports that accept copper or aluminum conductors while retaining a UL Listed status.With panel or 35 mm DIN-Rail** mounting for application flexibility these blocks are suitable for installation in wireways and industrial control panel feeder and branch circuits.* See table on page 5.** PDFFS504 panel mount only.Catalog number example:PDBFS204 is a 1-pole blockWhere:• The catalog symbol “PDBFS” defines the block as a finger-safe design.• The catalog number ending “204” in this example defines this block’s lineside and loadside characteristics covering the ampacity, number of ports and wire sizes, etc.• See the catalog number table for details on the available lineside/loadside characteristics.How to order:From the catalog number table, select the catalog number that defines the desired lineside/loadside port and conductor characteristics.Order one block per pole for the application. Multiple single-pole blocks can be ganged together via the dovetailing feature to form multi-pole configurations.Specifications:Ratings• Volts:• 600 V (UL)• 690 V (IEC)• Amps: 175 to 760 A• SCCR: Up to 200 kA (see table for circuit protection details)Agency information• UL 1953 Listed, Guide QPQS, File E256146• CSA® Certified, Class 6228-01, File 47235• RoHS compliant• CEFlammability rating• UL 94 V0Storage and operating temperature range • -4°F to 248°F (-20°C to 120°C)Conductors†• Stranded 75°C copper and aluminum• Higher temperature rated conductors permitted with appropriate derating† As specified in the catalog number table.2Technical Data 10536Effective June 2021Finger-safe power distribution blocks/bussmannseriesFeatures and benefits•IP20 finger-safe under specified conditions increases safety by isolating energized connections.•Wire-ready captive termination screws cannot be misplaced and are shipped “backed out” to save time on conductor installation.• Sliding DIN-Rail latch provides easy block mounting.•For multiple pole applications, all single-pole units can be gang mounted by using the interlocking dovetail pins that are pre-installed on the side of the blocks.•Elongated panel-mounting holes provide greater flexibility and installation ease when matching up with drilled panel holes.Dual wire port application•Rated for dual wire port application to increase the possiblenumber of lineside and loadside connections. E.g., PDBFS220 can accept two wires into the lineside port (#4 - #14 Cu, #4 - #8 Al) and two wires per port (eight connections total) on the loadside lug (#8 - #14 Cu, #8 Al).•Dual wire applications are only viable when using two wires of the same size, stranding, and insulating and conductor material.Ferrule terminal application•Bussmann series PDBFS power distribution blocks are rated for use with UL Listed ferrules (see catalog number table for details).•Ferrule applications allow for the use of a broader range of conductor stranding and simulate a more efficient, solid wire connection with the PDBFS terminal port.•Always use UL Listed ferrules in accordance with the manufacturer’s specifications and instructions.Catalog numbers:(customer supplied) applied according to the manufacturer’s specifications. Ferrule ratings apply to copper wire only.** See pages 4 and 5 for the tested upstream overcurrent protective devices necessary for achieving these SCCRs.† Torque rating for dual wire and ferrule application is 30.5 N•m (270 Lb-in).†† Torque rating for ferrule application is 13.6 N•m (120 Lb-in).3Finger-safe power distribution blocksTechnical Data 10536Effective June 2021/bussmannseries Selecting SCCR power distribution blocks and terminal blocksShort-circuit current rated power distribution blocksBussmann series power distribution blocks have three distinct styles to match different application needs. There are the PDBFS_ and PDB_ high short-circuit current rated power distribution blocks and the 16_ power terminal blocks. The differences are whether the power distribution blocks are enclosed or not, and whether they are UL 1953 Listed power distribution blocks or UL 1059 Recognized power terminal blocks, which have different minimum spacing requirements. The table on this page will assist you in selecting which block is right for your application.Why these are importantPer the NEC and OSHA, equipment cannot be installed in anelectrical system at a location where the available fault (short-circuit) current is greater than the equipment’s SCCR.Further, equipment SCCRs are required in the 2014 NEC and for UL 508A Listed control panels. Marking the equipment SCCR on control panels (NEC 409.110), industrial machinery electrical panelsSelection tableThis table provides an overview of the three Bussmann series power distribution and terminal blocks mentioned above. For details on the PDB_ blocks, see data sheet number 10537. For the 16_ blocks, see data sheet numbers 10533 (UL Recognized power distribution blocks),10534 (splicer blocks) and 10535 (stud blocks).PDBFS_distribution blocksY es***Y es Y es Y es Y es Y es Y esPDB_UL 1953 Listed powerdistribution blocksNo †Y es Y es Y es Y es Y es Y es, with optional cover 16_UL 1059 Recognizedterminal blocksNo †Y esNo ††Y esNo ††Y esNo* When protected by proper fuse class with maximum ampere rating specified or smaller.** For details, see PDB and TB minimum spacing requirements for equipment table below.*** IP20 finger-safe under specific conditions, see data sheet page 5.† Optional covers are available.

The PDBFS_ and PDB_ products have the increased spacing required for use in feeder circuits of equipment listed to UL 508A (UL 1059 terminal blocks must be evaluated for proper spacings). Also, for building wiring systems, the PDBFS_ andPDB_ power distribution blocks can be used to meet the 2014 NEC requirements in section 376.56(B) for power distribution blocks in wireways.See the last page of this data sheet for SCCR tools and resources to help you further understand and solve your SCCR needs.4Technical Data 10536Effective June 2021Finger-safe power distribution blocks/bussmannseriesUpstream fusing for SCCR and minimum enclosure dataThis table contains the tested SCCR levels for each PDBFS power distribution block using the specified lineside and loadside conductors and Bussmann series Class J, RK1, RK5 and T fuses.

Pneumatic Circuits A Regulator in a CircuitA regulator has two major functions. One is topass air at constant secondary pressure, regard-less of the flow variation or upstream pressure and the other is to reduce the pressure to a level that meets with work requirements, minimizing the amount of wasted pressurized air. Let's take a look at the first of these two functions.The force generated in a pneumatic system is directly proportional to the pressure existing at the actuator. Neglecting frictional forces, the higher the pressure, the higher the forces. The regulator controls the pressure. In many pneumatic sys-tems, a single regulator is used. However, there may exist a lower force requirement for a portion of the cycle. This is illustrated here by a clamp-press application with the desired clamping force being adjustable due to the nature or size of the part being clamped (Figure 1).By placing an additional regulator downstream of the main regulator, independent control of the clamping force can be accomplished. The main regulator controls the force of the double acting press cylinder. A procedure such as this could be followed for any multiple force system. Let us now consider function two, energy conservation.Large amounts of air are wasted when used at pressures higher than are actually required. The higher the pressure of a given volume of air in a cylinder, the greater the consumption of air. In many applications, the pressure used for the "non-work" part of the cycle is the same as the "work" portion. If the "non-work" pressure was less than the required "work" pressure, energy would be saved. There are some methods available to reduce the amount of compressed air used in a circuit, such as differential pressure and dual pressure. First let us look at a differential pressure circuit.Differential Pressure CircuitShown is a differential pressure circuit. The work is performed on the extension stroke while little force, hence a low pressure, is needed to retract the cylinder.A venting type regulator is installed in the head-end cylinder line allowing a considerable savings in air consumption. The cylinder with this arrange-ment uses reduced pressure acting as an air spring for returning the piston and rod and some external load. Also, notice that a three-way valve may be used since the pressure to the head end of the cylinder chamber remains constant (Figure 2). Dual Pressure CircuitAnother configuration for obtaining dual pressure is shown here. It utilizes the principle that many types of five-ported, 4-way valves may be used with either dual pressure or dual exhaust. Actua-tion of one solenoid allows one pressure to enter one end of the cylinder. Actuation of the other solenoid reverses the action as it allows a second pressure to enter the other end of the cylinder (Figure 3).CLAMP–PRESS CIRCUITDIFFERENTIAL PRESSURE CIRCUITSFIGURE 1FIGURE 2FIGURE 3Controls clamping forceSet for low pressureSet for workingpressureRegulator forextensionRegulator forretractionDUAL PRESSURE CIRCUITPneumatic CircuitsPlacement of a Flow Control in a Single Acting ApplicationPictured in Figure 4 is a single acting cylinder, flow control and three-way directional control valve.The cylinder will be able to move at an unrestricted speed in the upward direction. Upon releasing the directional control valve to the at-rest position, air exhausting from the cylinder must pass through the variable restriction (flow control) and theretraction rate will be controlled. A more common speed control circuit would contain a double acting cylinder.FIGURE 4Controlling the Speed of a Double Acting Cylinder Employing a Four Ported, Four Way ValveShown are two circuits controlling the rod speed of a double acting cylinder in one direction only. Both systems use a four-ported, four-way valve fordirectional control. In Figure 5-1, extension speed is controlled; in Figure 5-2, retraction speed is controlled. In both cases the ratio of flow into the cylinder in controlled by how fast the air is allowed to exhaust through the flow control.If independent control in both directions is needed,two controls must be used as in Figure 5-3. Here flow control (1) controls the speed of extension while flow control (2) controls the speed of retrac-tion. Note that flow controls are placed between the cylinder and directional control valve, prefer-ably as close as possible to the cylinder. Greater versatility can be achieved through the use of afive-ported, four-way valve.FIGURE 5-1FIGURE 5-2FIGURE 5-3Pneumatic CircuitsMultiple Speed ControlsBut many times two speeds are required as acylinder moves through its stroke. For instance, let us say that we have a cylinder with a stroke of 20in (508 mm). A fast forward speed of 20 ft/min (0.10 m/s) is needed for the first 10 inches(254mm) with a speed of 5 ft/min (0.025 m/s) for the remainder of the stroke. The desired return speed is 25 ft/min (0.125 m/s). It is evident that we need three speed controls and at least onedirectional control valve. By using a five-ported,four-way valve, the fast forward and return speeds can be obtained by installing needle valves in the two independent exhaust ports. This is shown in Figure 6-3. The slow speed forward remainder must now be obtained. For this section, a valve capable of sensing the cylinder rod position must be added. A normally open, two-way cam oper-ated valve can be used. It is placed in parallel with the slow speed flow control so that as the first 10in. (254 mm) of forward stroke is completed, flow is directed through the newly placed flow control. It may be a difficult task to place the cam in thecorrect position. This is because the valve must be actuated soon enough to allow for the build up of the back pressure required for the final traverse velocity. Let's go through the circuit one step at a time.The de-energized circuit is shown in Figure 7-1.When the main valve is energized, air is directed to the "A" port of the cylinder (Figure 7-2). Air exhausting from the "B" port flows through both cam valve "Y" and needle valve "Z", which isControlling Speed of a Double Acting Cylinder Employing a Five Ported, Four Way ValveA five-ported four-way valve provides two indepen-dent exhaust ports. In Figure 6-1, independent flow controls may be mounted in each exhaust port to control cylinder exhaust and thus speed in both directions. When the valve is energized(Figure 6-2), the supply is directed to cylinder port (A) and the exhausting air is passed through a needle valve (1). During retraction (Figure 6-3),supply is directed to cylinder port (B) and needle valve (2) controls the exhausting air. This direc-tional control valve has a definite advantage. First,it eliminates the need of a bypass check valve being incorporated in the body of the flow control valve. Second, this circuit also offers the opportu-nity of fewer connections since the needle valve can be fastened into the valve exhaust ports and not in the connecting lines.On the other hand, the control of the cylinder is not as good as when the control orifice is closely coupled to the cylinder. This is because of the need to bring the air up to the "controlled pres-sure" before control can be achieved. The long lines (volume of line), as compared to the cylinder control volume, will greatly affect when the control effect takes place. Also, it may be more difficult to wring the oil out of the exhaust air.FIGURE 6-1FIGURE 6-2FIGURE 6-3FIGURE 7-11212Pneumatic Circuits independently set to provide a motion of about 5ft/min (0.025 m/s). Most of the air travelsthrough the open cam valve and then passesthrough needle valve "1", which is adjusted after"Z" has been set, so that the two valves ex-hausting together provide a motion of 20 ft/min(0.10 m/s). When 10 in (254 mm) of forwardstroke is sensed, the cam valve shifts to itsclosed position (Figure 7-3). This causes tallthe air exhausting from the cylinder "B" port topass through needle valve "Z". Since the valvewas independently set to provide motion ofabout 5 ft/min (0.025 m/s), the sped of thecylinder is greatly reduced until the new pres-sure balance is established.Remember, the exact point of the stroke wherethis occurs is a variable, depending on thevolume in the exhaust lines between thecylinder "B" port, the line to the cam valve, andthe line to the "Z" needle valve. The entirevolume in these lines must be brought to thenew equilibrium pressure before the reducedspeed can be realized. For retraction (Figure 7-4), the directional valve is released, thus directing supply air to the cam valve "Y" whichis closed, needle valve "Z" and the check valve.Since the check has the least resistance, anearly unrestricted flow is fed into cylinder port"B". Air exhausting from "A" is passed throughthe directional control valve and into needlevalve (3) which is set at 25 ft/min (0.125 m/s),the required retraction speed.Once again, since needle valve (1) is notclosely coupled to the cylinder, some problemsof control may exist.3131MotionFAST FORWARDFIGURE 7-3ZSet at 5 FPMZYNormally Open 2-WayA BRod at 10 inchesFIGURE 7-4ZYA BSet at 25 FPMFIGURE 7-2FEED RATERETRACTIONPneumatic CircuitsPneumatic Flow Control ProblemsIn applications, any of the pneumatic controlsdiscussed above may present an objectionable "jump" or rapid partial stroking of the cylinder.

Supply pressure pushes thepiston, which in turn must push out the exhaust air.Until the exhaust air can build up a back pressure,the piston will accelerate; once balanced, steady motion should occur. This can occur if the direc-tional control valve is shifted before the cylinder completes its stroke, or if the valve is shifted too soon after the stroke is completed.Quick Exhaust ValvesThere are several special purpose valves that areused in pneumatic circuitry. A quick exhaust valve is an example of one. It is most commonly used in conjunction with a three- or four-way directional control valve to increase the exhaust flow (and thus generally increase the rod speed of the cylinder).The quick exhaust valve typically consists of aresilient disc in a body. The resilient disc "shuttles"side to side, changing the free flow paths through ports in the body.An improvement is achieved by placing needle valve "1" close to the cylinder (Figure 7-5). Now,even though adjustments are still interactive,problems with control may be diminished because trapped volumes have been reduced.Another change has been made in Figure 7-6.First of all, the two-way valve has been replaced by a three-way cam operated valve. This enables the flow controls to be placed so that minimum interactions take place. Also, they are closer to the cylinder, providing better control.Finally, the circuit in Figure 7-7 will give the best control of all the pneumatic circuits shown. The flow controls are even more closely coupled, and the flow control interaction is virtually nonexistent.(SAFETY NOTE: It is extremely difficult to control the speed of a pneumatic cylinder. This is due to the compressibility of air. Therefore, each speed control circuit must be examined very closely for all possible failure conditions.)In controlling the cylinder speed there are other problems that must be overcome. One such problem is "jump".FIGURE 7-5FIGURE 7-6SlowFIGURE 7-7Pneumatic Circuits How a Quick Exhaust Valve WorksThe quick exhaust valve is typically used in con-junction with three- or four-way directional controlvalves. When its inlet port (1) is connected to thesupply pressure, it automatically seals its exhaustport (3) and allows pressure to enter the cylinder (2). If the valve is of the "floppy disk" design, a control valve is shifted so that it can exhaust the supply to the cylinder. The resilient disc moves away from the exhaust port and allows the trapped air in the cylinder to quickly exhaust directly to the atmosphere. This eliminates the need for exhaust air from the cylinder to flow through long, often somewhat restrictive, lines to a main control valve. Quick exhaust devices should be connected (in juxtaposition) to the cylinder port to give rapid cylinder velocities.A Quick Exhaust Valve in a Circuit One application for a quick exhaust valve is using single acting spring return cylinders. With a standard circuit, many times the return speed may be too slow. This may be due to inadequate spring force, high frictional resistance due to the load or the restriction of exhaust flow or a combination of several of these factors.Shown in Figure 8-1 is a single acting cylinder with a quick exhaust valve closely coupled to the cylinder. This permits greater cylinder speeds than would exist if the air from the cylinder were ex-hausted through the directional control valve, but without increasing its size. During extension of the cylinder, the quick exhaust is part of the supply system that feeds air to the cylinder (Figure 8-2). However, during the return stroke, the quick exhaust shifts as soon as the pressure between it and the directional control valve drops below the pressure at port C. This permits free exhausting of the air from the cylinder directly to the atmosphere, bypassing the directional control valve and all the interconnecting lines.Quick exhaust valves may also be added to double acting cylinder applications. Shown in Figure 8-3is an application that will deliver an impact blow. In this circuit, a quick exhaust was incorporated at the cap end for high return speed. Note that the volume of air under pressure in our example will act as an air spring.QUICK EXHAUST V ALVEMotionMotion RETRACTIONEXTENSIONFOR VERY RAPID SPEEDQuick exhaust valveclose coupled to cylinderFIGURE 8-3FIGURE 8-2FIGURE 8-1Pneumatic CircuitsSHUTTLE VAL VE&Quick Exhaust Used as ShuttlesMany quick exhaust valves may also be used as shuttle valves. Shuttle valves are automatic flow path selectors which allow the higher of twopressures to be directed into a flow path. The use of such devices is common in control circuits to "select" the higher sources of pressure within the circuit. However, when exhausting a large volume of air through a large valve, especially through a quick exhaust valve directly to the atmosphere,unwanted air noise may become a problem.Sample Circuit – Controlling T wo Movements with One ValveA single valve can control two movements simulta-neously while delaying one actuator in eitherdirection (Figure 9). This is accomplished by using two remote operated 4-way valves and a 3-way valve. In this circuit, the main 3-way valve (3),when actuated, will direct pressure to the pilot ports of the 4-way valves (1 & 2). The flow control (FC1)will prevent a rapid rod extension allowing the other actuator to complete the stroke first. When the 3-way valve is returned to the normal position, the pilot pressure is exhausted from both pilot ports.The flow control (FC2) will restrict the removal of pilot pressure from valve (1) and will delay the retraction of the actuator. A small volume of air between the pilot port of valve (1) and the flow control will help increase the time of delay.Sample Circuit – Manual Advancewith an Automatic ReturnThe circuit in Figure 10 will provide a manual advance with an automatic return, regardlesswhere the cylinder piston rod is physically stopped during the extension. The advance is accom-plished by momentarily actuating the 3-way valve which will supply a momentary pressure to the pilot of the 4-way directional control valve. This willadvance the cylinder. Back pressure in the rod end of the cylinder is present until the piston rod comes to rest. At this point, the threshold sensor senses the absence of pressure (6 to 9 PSIG) on the rod end of the cylinder and sends a momentary pilot signal to the other pilot port of the 4-way valve. The valve will shift and return the cylinder to the normally retracted position. A second threshold sensor could be used for a reciprocating system.Threshold sensors can be found in the Limits &Sensors section of this catalog.Portions excerpted from the Schrader Bellows Industrial Pneumatic Technology Handbook.FIGURE 9FIGURE 10。

The sequenced design prevents the finger from retracting until the pin is fully extended. The part can move the amount of clearance between the lock bracket and adjustment screw, but the extended finger keeps the part trapped securely on the pin.Unless otherwise specified, the factory lock default setting is MT20= 2.0 mm material.Adjustment procedures for PLK lock with material specified:1) Start in the unclamped position, with the pin up, and the finger(s) retracted into the pin.2) Install the part support (item 5) with the adjustment slot over the adjustment screw (item 8). Install the flange plate over the part support aligning the adjustment screw and two holes as shown. Hand tighten two times (item 7). (See Figures 1 and 2.)3) Install the shims to match the panel thickness requested. Close the clamp on the shims with air pressure (87 psi [6 bar]).4) Make sure the lock bracket (item 14) rotates counterclockwise into position under the adjustment screw (see Figure 3). Turn the adjustment screw clockwise until it contacts the top of the lock bracket (see Figure 4).5) After touching, back the adjustment screw off one full turn to assure clearance so the lock bracket is free to rotate clockwise when the clamp opens (see Figure 5).6) Unclamp the unit, remove the shim and two fasteners (item 7).7) Rotate the flange plate (item 6) on the part support and align the four mounting holes as shown. (Figure 6)8) Add the four screws (item 7) and tighten to 44 in-lbs [5 Nm].FIGURE 3FIGURE 4FIGURE 5FIGURE 6TOP VIEWFIGURE 1ALIGNED WITH PART SUPPORT SLOT AND FLANGE SLOTCOUNTER-CLOCKWISELOCKING MECHANISM & MANUAL OPENINGThe Series PLK incorporates a locking mechanism that keeps the pinretracted and the finger extended so panels are trapped in positionon the pin. The locking mechanism does not maintain clamp forcewhen pressure is lost. During normal operation, air pressure movesthe piston, releasing the lock, allowing the pin to extend, the fingerto retract, and unclamp the part. To manually unlock the clamp, firstremove air pressure, then loosen the screw and rotate the cover outof the way. Insert a small screwdriver under the dowel pin and lift itup. This will release the lock, extend the pin, and retract the finger.(See diagram.) The R01 or R02 option can also manually unlock theclamp. First, remove air pressure then push the rod into the cylinder,moving the piston. This will release the lock, extend the pin, andretract the finger.
