Allen-Bradley 1492-IFM20D24A-2 Interface Module

The Allen-Bradley 1492-IFM20D24A-2 is a 20-point digital interface module (IFM) in the 1492 family, designed to collect digital input signals from field devices and present them to a Rockwell Automation PLC via fixed terminals on a DIN-rail mounting platform. Operable from 24V AC/DC and featuring LED indicators for quick status checks, the module provides 20 digital input points and includes extra input terminals to simplify wiring of sensors and switches. Built for use with the 1492 I/O backplane, this module integrates into standard Allen-Bradley control architectures and supports straightforward installation and maintenance in industrial automation environments. Mounting on a DIN rail with fixed terminals, the 1492-IFM20D24A-2 is commonly employed to interface devices such as limit switches, proximity sensors, and pushbuttons to the PLC, delivering reliable digital input signaling in machine control and process automation.
