It transfers digital signals (NAMUR sensors/mechanical contacts) from a hazardous area to a safe area.Each proximity sensor or switch controls a passive transistor output for the safe area load. The normal output state can be reversed using switch S1 for channel I and switch S2 forchannel II. Switch S3 enables or disables line fault detection of the field circuit.During an error condition, the transistors revert to their de-energized state and LEDs indicate the fault according to NAMUR NE44.A unique collective error messaging feature is available when used with the Power Rail system.2Features17-08-09 14:30D a t e o f i s s u e 2017-08-09181005_e n g .x mlGeneral specifications Signal typeDigital Input Functional safety related parameters Safety Integrity Level (SIL) SIL 2Supply Connection Power Rail or terminals 14+, 15-Rated voltage U r 20 ... 30 V DC Ripple ≤ 10 %Rated current I r≤ 50 mA InputConnection side field sideConnection terminals 1+, 2+, 3-; 4+, 5+, 6-Rated valuesacc. to EN 60947-5-6 (NAMUR), see system description for electrical data Open circuit voltage/short-circuit current approx. 8 V DC / approx. 8 mA Switching point/switching hysteresis 1.2 ... 2.1 mA / approx. 0.2 mALine fault detection breakage I ≤ 0.1 mA , short-circuit I > 6 mA OutputConnection side control sideConnection output I: terminals 7, 8 ; output II: terminals 8, 9Switching voltage ≤ 30 VSwitching current ≤ 100 mA , short-circuit protectedSignal level 1-signal: switching voltage - 2.5 V max. at 10 mA switching current or 3 V max. at 100 mA switching current 0-signal: switched off (off-state current ≤ 10 µA)Output I, IIsignal ; electronic output, passive Collective error message Power Rail Transfer characteristics Switching frequency ≤ 5 kHzGalvanic isolation Input/Output reinforced insulation acc. to IEC 62103, rated insulation voltage 300 V rmsInput/power supply reinforced insulation acc. to IEC 62103, rated insulation voltage 300 V rms Output/power supply basic insulation according to IEC 62103, rated insulation voltage 50 V effInput/inputnot availableOutput/Output not availableIndicators/settings Display elements LEDs Control elements DIP-switchConfiguration via DIP switchesLabelingspace for labeling at the front Directive conformity Electromagnetic compatibilityDirective 2014/30/EU EN 61326-1:2013 (industrial locations)Conformity Galvanic isolationIEC 62103:2003Electromagnetic compatibility NE 21:2004Degree of protection IEC 60529:2001InputEN 60947-5-6:2000Ambient conditionsAmbient temperature -20 ... 60 °C (-4 ... 140 °F)Mechanical specifications Degree of protection IP20Connection screw terminalsMass approx. 150 gDimensions 20 x 119 x 115 mm (0.8 x 4.7 x 4.5 inch) , housing type B2Mountingon 35 mm DIN mounting rail acc. to EN 60715:2001Data for application in connection with hazardous areasEU-Type Examination Certificate PTB 00 ATEX 2035Marking ¬ II (1) G [Ex ia] IIC¬ II (1) D [Ex ia] IIIC InputEx ia IIC, Ex ia IIIC Voltage U o 10.5 V Current I o 13 mA17-08-09 14:30D a t e o f i s s u e 2017-08-09181005_e n g .x mlOutputMaximum safe voltage U m40 V DC (Attention!

See specifications for pulse width and rise/fall timemeasurements for additional restrictions on signaltiming characteristics.Measurement SpecificationsAuto arming: Measurements are initiated immediately and acquired as fast as possible, using a minimum number of signal edges. Timed arming: The duration of the measurement is internally timed to a user-specified value (also known as the “gate time”).Digits arming: Measurements are performedto the requested resolution (number of digits) through automatic selection of the acquisition time.External arming: An edge on the external arm Input enables the start of each measurement. Auto arming, timed arming modes or another edge on the external arm input may be used to complete the measurement.Time interval delayed arming: For time intervalmeasurements, the stop trigger condition isinhibited for a user-specified time following thestart trigger. The 53132A offers advanced timeinterval arming capabilities including use of userspecified time or Channel 2 events to delay bothstart and stop triggers.Measurement limitsLimit checking: The measurement value ischecked against user-specified limits at theend of each measurement.Display modes: The measurement result maybe displayed as either the traditional numericvalue or graphically as an asterisk movingbetween two vertical bars.Out-of-limits Indications:• The limits annunciator will light on the frontpanel display.• The instrument will generate an SRQ ifenabled via GPIB.• The limits hardware signal provided via theRS-232 connector will go low for the durationof the out-of-limit condition.• If the analog display mode is enabled, theasterisk appears outside the vertical bars,which define the upper and lower limits.Input signal frequency or timeGraph 6:Trigger level timing error(Level setting error andinput hysteresis)7.

Both devices feature 60Ω(typ) on-resistance with 0.03Ω(typ) on-resistance flatness. These low on-resistance multiplexers conduct equally well in either direction.The MAX14752 is an 8-to-1 multiplexer and MAX14753is a dual 4-to-1 multiplexer. Both devices operate with dual supplies of ±10V to ±36V or a single supply of +20V to +72V. Both devices can also operate with unbalanced supplies, such as +36V and -10V. These multiplexers support rail-to-rail input and output signals.The control logic level is defined via the EN input. These devices do not require power-supply sequencing.Applications InformationCurrent Through the MuxThe current flowing through each on-channel of the MAX14752/MAX14753 multiplexers must be limited to ±5mA for normal operation. If the current exceeds this limit, an internal leakage current from that channel to V SS appears. Larger input current does not destroy the device if the max power dissipation is not exceeded.Input Voltage ClampingFor applications that require input voltages beyond the normal operating voltages, the internal input diodes to V DD and V SS can be used to limit the input voltages. As shown in Figure 11, series resistors can be employed at the inputs to limit the currents flowing into the diodes dur-ing undervoltage and overvoltage conditions. Choose thelimiting resistors such that the input currents are limited to I IN_(max) = 100mA. The values of the current limit resis-tors can be calculated as the larger of R LIM+and R LIM-.During an undervoltage or overvoltage condition, the input impedance is equal to R LIM . The additional power dissipation due to the fault currents needs to be calcu-lated. The MAX14752/MAX14753 multiplexer operates normally on a channel that is on during an overvoltage or undervoltage clamping condition on a second chan-nel that is not switched.Beyond-the-Rail InputIf input voltages are expected to go beyond the supply voltages, but within the absolute maximum supply volt-ages of the MAX14752/MAX14753, add two diodes in series with the supplies as shown in Figure 12.During undervoltage and overvoltage events, the internal diodes pull V DD /V SS supplies up/down. An advantage of this scheme is that the input impedance is high and currents do not flow through the MAX14752/MAX14753during overvoltage and undervoltage events. The input voltages must be limited to the voltages specified in the Absolute Maximum Ratings section.R V (max –V I (max R V –V (LIM+IN_DDIN_LIM -SS IN_==))m in I (max IN_))Figure 11.
