Temperature converter D6273S

signalRS-485Modbus RTU

The Temperature Converter & Trip Amplifier D6273 accepts a low level dc signal from millivolt, thermocouple or 2-3-4 wire RTD or transmitting potentiometer sensors, and converts, with isolation, the signal to drive a 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 automatic, using an internal temperature sensor or fixed to a usercustomizable temperature value. D6273S offers two independent trip amplifiers via two SPDT output relays. FEATURES SIL 2 / SC 3 mV, TC, 2/3/4wire res./RTD or potentiometer input Two independent Trip Amplifiers (SPDT relay contacts) Inversion/scaling/custom output Selectable CJC: internal PT1000, external RTD or fixed Fastest integration time: 50 ms Burnout/internal/cjc/in sensor fault monitor Alarm output with user-settable trip points Modbus RTU RS-485 for monitor & configuration Fully programmable operating parameters High Accuracy, µP controlled A/D converter Three port isolation, Input/Output/Supply
