Item no. 857-810

Temperature signal conditioner for thermocouples; Current and voltage output signal; Configuration via DIP switch; Supply voltage: 24 VDC; 6 mm module width; light gray


Short description:

This temperature signal conditioner records signals from type J and K thermocouples and converts the temperature signal into a standard analog signal on the output side.


  • For type J and K thermocouples
  • Cold junction compensation (on/off)
  • Switching between measurement ranges is calibrated
  • Detect sensor's wire break
  • Detect measurement range underflow/measurement range overflow
  • Integrate a switchable clipping function to limit the standard analog signal to the upper range values
  • Safe 3-way isolation with 2.5 kV test voltage per EN 61140
