Stock item

Short description:

This temperature signal conditioner records Pt100, Pt200, Pt500, and Pt1000 sensors, as well as resistors up to 4.5 kOhm, converting the temperature signal into a standard analog signal at the output.


  • PC configuration interface
  • For Pt100, Pt200, Pt500 and Pt1000 sensors, as well as resistors up to 4.5 kOhm
  • 2-, 3- and 4-wire connection technology
  • Detects calibrated measurement range switching
  • Detects a sensor wire break/short circuit
  • Measurement range underflow/overflow
  • Clipping capability for analog signal limitation to output end values
  • Safe 3-way isolation with 2.5 kV test voltage per EN 61140


Additional setting options as well as output signal inversion via interface configuration software or interface configuration app
