Input module CPX-4AE-TC
for thermocouples

Input module CPX-4AE-TC for thermocouples show enlargement

New I/O modules for processes with numerous analogue channels for temperature sensors

The temperature sensor modules CPX-4AE-TC provide many analogue I/O channels for recording temperatures from -270 to 1,820 °C, and for type B, E, J, K, N, R, S and T thermocouples. For use in process automation or manufacturing processes.

The benefits to you:

  • Channel-based diagnostics – reduced downtimes
  • 4 channels per module – reduced channel costs
  • Avoids expensive sensors with integrated signal converters
  • Reduced system costs thanks to simple function integration in fieldbus/Ethernet networks
  • Component of the modular electric CPX terminal

Cold junction compensation

In order to obtain a precise measured value, we need to know the temperature at the sensor point of contact. An additional sensor attached to the M12 plug or on the manifold block's CageClamp identifies this temperature. Suitable PT1000 sensors can be ordered from Festo (CPX-WPT1000).
