Allen-Bradley | 1734-TBCJC | POINT I/O

Product Description: Allen-Bradley 1734-TBCJC

The Allen-Bradley 1734-TBCJC is a POINT I/O terminal base specifically designed for use with thermocouple input modules. It includes an integrated cold junction compensation (CJC) sensor that enables accurate temperature measurement by compensating for the junction temperature at the terminal connection. This terminal base ensures precise signal conditioning for temperature inputs in industrial applications.
