B&R X20ATA492

Single-channel electrical isolation Integrated terminal temperature compensation 2x PT1000 sensor integrated in the terminal 2x external PT1000 sensor can be connected, 2-wire or 4-wire connections NetTime timestamp: Moment of measurement The module is equipped with 2 inputs for J, K, N, S, B, R, E, C and T thermocouple sensors. The 2 measurement channels are electrically isolated from each other. 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.
