Allen-Bradley 1734-IM4 POINT I/O AC Input Module Compact

Product Description

The Allen-Bradley 1734-IM4 is a POINT I/O digital AC input module from Rockwell Automation’s Bulletin 1734 family. It provides four AC input channels for monitoring discrete signals from field devices such as push buttons, limit switches, and sensors operating at 120 V AC or 240 V AC.

Compact and DIN-rail mountable, the 1734-IM4 integrates seamlessly into distributed I/O architectures, reducing wiring complexity and enabling scalable automation systems. It is compatible with ControlLogix® and CompactLogix® systems via POINT I/O adapters, making it suitable for industrial automation applications requiring flexibility and reliability.
