The MCC 134 is a 24-bit, 4-channel HAT add-on module for measuring thermocouples, providing professional-grade accuracy and is the best choice among similar products. Users can connect up to 4 differential thermocouples (TC) to the input channels of the MCC 134. The TC model for each channel can be selected via software. The thermocouple inputs are electrically isolated from the Raspberry Pi, minimizing noise and providing electrical protection in harsh electrical environments.
The MCC 134 features 3 high-resolution cold junction compensation (CJC) sensors. It is equipped with an open-circuit thermocouple detection (OTD) for all TC input channels, allowing users to monitor the circuit board for damaged or disconnected thermocouples.
Features
4-channel isolated thermocouple input, 24-bit A/D converter, 1-second update interval, minimum support for J, K, R, S, T, N, E, and B type thermocouples, cold junction compensation (CJC), linearization, screw terminal connections.
