Temperature regulator signal converter D5072S

DIN railSIL 3for RTD sensors

I.S. SIL2 Multifunction Temperature ConverterThe Multifunction Temperature Converter D5072 accepts a low level dc signal from millivolt, thermocouple or 2-3-4 wire resistance/RTD or transmitting potentiometer sensor, located in Hazardous Area, and converts, with isolation, the signal to drive a Safe Area load, suitable for applications requiring SIL 2 level in safety related systems for high risk industries. Output signal can be direct or reverse. Modbus RTU RS-485 output is available on Bus connector. Cold junction compensation can be programmed as Internal: provided by an internal PT1000 sensor; Fixed: to a user-customizable temperature value; External remote: ext. RTD placed away, on a support terminal board; External local: ext. RTD placed close to the module terminal block; Other: connecting compensation RTD to one of the two ch. For D5072D module: duplicator function provides two independent outputs from one single input. Output function can be configured as: Adder, subtractor, low/high selector. Modules are provided with alarm function, which is available via photoMOS output.SIL 2 / SC 3Input from Zone 0/Div. 1Installation in Zone 2/Div. 2mV, TC, 2/3/4wire res./RTD or potentiometer inputDuplication/inversion/scaling/custom outputSelectable CJC: internal PT1000, external RTD or fixedBurnout/internal/cjc/in sensor fault monitorAlarm output with user-settable trip pointsModbus RTU RS-485 for monitor & configurationFully programmable operating parametersHigh Accuracy, µP controlled A/D converterThree port isolation, Input/Output/SupplyHigh Density, two channels per unitSupplyVoltage24 Vdc nom (18 to 30 Vdc), reverse polarity protectedCurrent Consumption42 mA @ 24 Vdc with 20 mA out, typical.Power Dissipation0.9 W @ 24 Vdc with 20 mA out, typical.InputTypeMillivolt, thermocouple, 2-3-4 wire RTD or 3 wire transmitting potentiometer.
