Allen-Bradley 1492-IFM20F-3 Sensor Interface Module

The Allen-Bradley 1492-IFM20F-3 Sensor Interface Module is a 20-point feed-through digital interface module (IFM) designed for the Rockwell Automation 1492 I/O wiring system. It provides 20 digital input points with 3-wire sensor type inputs, enabling direct connection of field sensors to pre-wired 1492 cables that terminate into an I/O module. This module is designed for DIN-rail mounting and works with the pre-wired 1492-CAB cables to simplify panel wiring, reduce in-panel wiring, and streamline maintenance by consolidating sensor wiring in a single assembly. The 1492-IFM20F-3 variant supports 3-wire sensor inputs, making it well suited for common automation sensors such as proximity sensors and photoelectric sensors used in manufacturing, packaging, and process automation. As part of the Allen-Bradley 1492 family, it replaces traditional point-to-point wiring with a pre-engineered interface that supports scalable sensor configurations across multiple channels. When used with the Rockwell 1492 wiring ecosystem, this module helps establish a consistent, organized field wiring topology, facilitating diagnostics and future expansion for multi-sensor systems.
