Material number:
  • 6 channels for thermocouples
  • For sensor types J, K, N, S, B, R, E, C, T, raw value measurement
  • Integrated terminal temperature compensation
  • 2x PT1000 sensor integrated in the terminal (X20TB1E)
  • 2x external PT1000 sensor can be connected (X20TB1F)
  • Configurable filter time
  • NetTime timestamp: Moment of measurement

The module is equipped with 6 inputs for J, K, N, S, B, R, E, C and T thermocouple sensors.

This module can also be equipped with the X20TB1E thermocouple terminal block with integrated PT1000 temperature sensors. This makes it possible to achieve optimal terminal temperature compensation.
