Allen-Bradley 1492-IFM40DS24-4 Digital Interface Module

The Allen-Bradley 1492-IFM40DS24-4 is a 40-point isolated digital interface module in the 1492 Wiring System family, providing galvanic isolation between field devices and the controller while delivering 40 discrete digital I/O points. It operates on 24/48 V AC/DC and includes LED indicators for status, using a fixed 40-pin terminal block with four field wiring terminals per I/O connection to simplify wiring. Designed to interconnect digital inputs and outputs with compatible 1492 I/O networks, this module enables compact, modular expansion of control logic for industrial automation tasks. Its isolated channels help protect the controller from transients and faults, making it suitable for sensing, discrete control, and sequencing in manufacturing environments.
