MCC134 Thermocouple Measurement DAQ HAT

Digilent's measurement computing MCC134 is a thermocouple measurement HAT (hardware attached on top) designed for use with Raspberry Pi®. It features a 24-bit resolution and provides professional-grade accuracy. The MCC134 provides four isolated thermocouple inputs. Users can connect up to four differential thermocouples (TC) to the MCC134 input channels. TC types are software-selectable per channel. TC values can be updated every second, minimum. The MCC134 is equipped with open thermocouple detection (OTD) for all TC input channels so users can monitor the board for broken or disconnected thermocouples. It also has three high-resolution cold-junction compensation (CJC) sensors.

HAT configuration parameters are stored in an on board EEPROM that allows the Raspberry Pi to automatically set up the GPIO pins when the HAT is connected. The open-source MCC DAQ HAT library of commands in C/C++ and Python allows users to develop applications on the Raspberry Pi using Linux. The MCC DAQ HAT library supports operation with multiple MCC DAQ HATs running concurrently. Console-based and user interface (UI) example programs are available for each API.
