1734-IK Allen-Bradley POINT I/O Galvanic Isolation Module

Product Description

The Allen-Bradley 1734-IK is a POINT I/O isolation module from Rockwell Automation’s Bulletin 1734 family. It is engineered to provide galvanic isolation between field wiring and the POINT I/O backplane, protecting sensitive I/O modules from electrical noise, voltage transients, and ground loops.

The 1734-IK does not perform input or output functions; instead, it serves as a protective interface to maintain signal integrity in distributed automation systems. It is ideal for applications with different grounding schemes, long cable runs, or electrically noisy environments, such as process control, packaging, and machine automation systems.
