Allen-Bradley 1756-CJC

Allen-Bradley 1756-CJC

Overview

The Allen-Bradley 1756-CJC is a Cold Junction Compensation (CJC) sensor designed for use with ControlLogix thermocouple input modules. It ensures accurate temperature measurement by compensating for the temperature differences at the terminal block, a critical requirement when using thermocouple sensors.

This compact component is mounted directly into the 1756-RTB (Removable Terminal Block) and is essential for achieving precision in temperature monitoring applications.
