P-64The CN2400 Series are precision PID, self tuning temperature controllers, in 1⁄4and 1⁄8DIN sizes.They have modular hardwareconstruction with an alarm option, and depending on the model, can accept a wide variety of field installable input,output, and communicationsmodules.The CN2404/08 controllers come with two digital inputs as part of their standard configuration. The control outputs, depending on type,can be configured for either heating,cooling or alarm.Precise ControlAn advanced PID control algorithm gives stable control of the process.A one-shot tuner is provided to set up the initial PID values and to calculate the overshoot inhibition parameters,for both heating and coolingapplications. In addition, an adaptive tuner will handle processeswith continually changingcharacteristics. Power feedback employs power control techniques which stabilize the controlledtemperature against supply voltage fluctuations on electrically heated loads. Dedicated cooling algorithms ensure optimum control of fan, water and oil cooled systems.Universal InputA universal input circuit with anadvanced analog to digital convertor samples the input at 9 Hz andcontinuously corrects it for drift. This gives high stability and rapidresponse to process changes. High noise immunity is achieved by rejection of 50/60 Hz pick-up and other sources of noise. Sensor diagnostics are also provided. The input covers all thermocouple types,Pt100 RTD and linear millivolts or milliamps. Input filtering from Off to 999.9 seconds is standard.Customized OperationCustom LEDs provide a bright, clear display of the process value and setpoint. Front panel auto/manual and run/hold buttons are provided.Optional Ramp and Soak profile features are available, as well as valve positioning control.AlarmsUp to four process alarms can be combined onto a single output. They can be full scale high or low,deviation from setpoint, rate ofchange or load failure alarms. Alarm messages are flashed on the main display. Alarms can be configured as latching or non-latching and also as ‘blocking’ type alarms which means they will become active only after entering a safe state.PDLINK Mode 1 Load Diagnostics PDLINK is a major innovation in the CN2404 and CN2408. When used in combination with an OMEGA ®SSC-TE10S solid state contactor, it allows the dc Pulse output of a CN2404 or CN2408 to transmit the power demand signal andsimultaneously read back a load fault alarm on the same pair of wires. This alarm will flash as a message on the controller frontpanel and can trip the alarm relay. It indicates that there is a fault in the heating circuit caused by either fuse failure, SSC open or short circuit,heater open circuit or the absence of line supply.CN2404 Series$529Basic UnitCN2408 Series$479Basic UnitShown smaller than actual size1⁄8DIN1⁄4DINCN2100, CN2200 & CN2400 Family CN2404 and CN2408 SeriesTemperature and Process ControllersProgramFeaturesߜPID or ON/OFF Control ߜHeating and Cooling ߜOne Shot Tuner withOvershoot Inhibition ߜSetpoint Rate Limit ߜUniversal TemperatureInputߜScalable LinearProcess Input ߜControl OutputsConfigurable asReverse/Direct Action or AlarmߜMultiple Alarms Configuredon a Single OutputOptional FeaturesߜRS-232, RS-422, orRS-485 Communications ߜ10 amp Heating Output(CN2404 only)ߜAnalog RetransmissionOutput (Isolated)ߜRemote Setpoint ߜRamp & SoakߜValve Positioner Control ߜCustom IR RangesavailableSpecificationsInputProcess Input Range:±100 mV and 0 to 10 Vdc Sample Rate:9 Hz (110 mS) Calibration Accuracy:0.2% of reading, ±1 LSD, ±1°C/F Resolution:<1 µV for ±100 mV range, <0.2 mV for 10 Vdc range Linearization Accuracy:No discernable errorZero Drift with Ambient Temperature:<1 µV per °C for ±100 mV range, 0.1 mV per °C on 10 Vdc rangeGain Drift with Ambient Temperature:<0.004% of reading per °CInput Filter:OFF to 999.9 secs Zero and Span Offset:User adjustable over the full display range Thermocouple Input Types:Refer to sensor inputs and display ranges table.
