This is the thermocouple termination board for the Low Energy PIU. This board provides screw terminals for the incoming thermocouple field wiring, and provides the CJR reference as well.

This termiation board is combined with the 51301874-100 thermocouple relay board to provide 16 points of thermocouple input for the Low Energy PIU.

WPC now offers the 51301880-101, a new termination board for the LE PIU, 100% compatible with the original, and featuring new terminal blocks for faster field wiring.
