Frequently Asked Questions

What thermocouple types does the MCC 134 support?

The Digilent MCC 134 supports a comprehensive range of thermocouple types including J, K, R, S, T, N, E, and B. Each of the four isolated channels can be individually configured to the specific thermocouple type being used, providing flexible measurement options for various applications.

Can multiple MCC 134 HATs be used on a single Raspberry Pi?

Yes, the MCC 134 is designed for stackable operation. Users can stack up to eight MCC HATs onto a single Raspberry Pi, allowing for the creation of multi-channel, multi-function data acquisition systems. This expandability is ideal for complex monitoring needs.

What software support is available for the Digilent MCC 134?

Digilent provides open-source libraries and examples for both C/C++ and Python, making integration into Raspberry Pi OS straightforward. Comprehensive API documentation is also supplied, enabling developers to easily program and interface with the MCC 134 for data acquisition tasks.

What is cold junction compensation (CJC) and why is it important for the MCC 134?

Cold junction compensation (CJC) corrects for the temperature difference between the thermocouple's measuring junction and the reference junction at the DAQ HAT. The MCC 134 integrates CJC to ensure accurate and reliable temperature readings, compensating for ambient temperature fluctuations at the board's terminals.

Does the MCC 134 HAT require external power?

No, the MCC 134 draws its power directly from the Raspberry Pi's 40-pin header. It is designed to be powered solely by the Raspberry Pi, simplifying setup and reducing cable clutter. This makes it convenient for portable or embedded data logging applications.
