Allen-Bradley 1492-IFM40D24-3 Interface Module

The Allen-Bradley 1492-IFM40D24-3 is a 40-point digital interface module (IFM) in the 1492 Programmable Controller Wiring System, delivering 40 fixed I/O points on a 40-pin terminal block with three field-side wiring terminals per I/O connection. It operates from 24 V power with LED indicators (24 V AC/DC) on the face to show channel and power status, and it supports 3-wire sensor type inputs, making it suitable for common three-wire industrial sensors. Designed for DIN-rail mounting, the unit is used to connect digital field devices to Rockwell Automation controllers via pre-wired and pre-tested cables, enabling reliable density in control panels where you need to organize multiple I/O channels in a single module. As part of the 1492 family, this IFM consolidates wiring between the field and the controller while offering per-channel visibility via its LED indicators.
