1492-IFM40D24

Overview of Allen Bradley 1492-IFM40D24-2

The Allen Bradley 1492-IFM40D24-2 is a 40-point digital interface module designed to streamline programmable controller wiring in industrial automation panels. This module operates on 24V AC/DC power and features integrated LED indicators for real-time status monitoring. Built for flexibility, the 1492-IFM40D24-2 connects to digital I/O systems ranging from 16 to 32 points through a keyed 40-pin cable connector with secure locking tabs. The fixed terminal block configuration supports high-density field wiring with terminals that accommodate wire sizes from #22 to #12 AWG. Each circuit handles continuous current up to 2A, making it compatible with higher-current PLC output modules. The module mounts quickly on standard DIN rail and ships with pre-printed and blank adhesive marking strips for clear terminal identification. This IFM reduces engineering time by eliminating point-to-point wiring while minimizing errors through pre-tested cable connections. The LED-indicating style provides instant visual feedback for troubleshooting and system diagnostics.
