Allen-Bradley | 1734-IT2I | POINT I/O

Product Description: Allen-Bradley 1734-IT2I

The Allen-Bradley 1734-IT2I is a 2-channel thermocouple input module in the POINT I/O system, designed for precise and isolated temperature measurements. It supports a wide range of thermocouple types and offers built-in cold junction compensation (CJC) via compatible terminal bases. With per-channel isolation and high resolution, the module is ideal for temperature monitoring in sensitive industrial environments.
