Allen-Bradley 1492-IFM40F-F-2 Interface Module

Allen-Bradley 1492-IFM40F-F-2 Interface Module is a 40-point isolated fusible digital interface module (IFM) in Rockwell Automation’s 1492 wiring systems. It provides 40 digital I/O points with isolated inputs and uses 5 x 20 mm fuse clips for field protection, plus extra terminals for outputs. This digital interface module is designed to connect field devices to AB digital I/O modules within a 1492 wiring system, enabling protected, organized wiring in control panels or distributed I/O installations. The fusible 40-point design protects individual channels while preserving a compact, feed-through interface that can be paired with other 1492 components and prewired cables to simplify installation. As part of the 1492 Programmable Controller Wiring Systems family, it supports AB's standardized interface approach for industrial automation and helps maintain clear fault isolation across channels. Typical input types include digital signals from sensors and switches; outputs support driving relays or actuators through compatible I/O modules. Compact form factor and dedicated fuse protection contribute to easier maintenance and safer operation in harsh industrial environments.
