DIN Rail Temperature Transmitter Signal Converter

Single-channel DIN Rail PID Temperature Signal Converter

Widely used for ovens, incubators, brewing, warming/chilled cabinets, food processing, plastic manufacturing, and process applications requiring heat/cool control and process protection alarms in a compact DIN rail mounting package.



CHR-2000 Din rail mounted signal convertor 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.
