Allen-Bradley 1492-IFM20F Industrial Interface Module

Allen‑Bradley 1492-IFM20F is a 20-point feed-through digital interface module (IFM) in the 1492 Sensor Interface Modules family, designed to connect digital I/O from field devices to a Rockwell Automation 1492 wiring system via a fixed terminal block. The module uses field-side terminals, with one terminal per I/O connection, and employs a cable connector pin type described as interfacing to digital I/O from 8 to 16 points, enabling flexible branching of digital signals. It is specified as a 0 to 264 V AC/DC compatible device, suitable for interfacing a range of AC or DC digital inputs and outputs within the 1492 network. As a standard digital module with a fixed terminal block, the 1492-IFM20F features a through (feed-through) interface design that simplifies wiring in control panels and minimizes intermediate wiring steps. This module is part of the Allen-Bradley 1492 family of connection devices, intended to facilitate reliable, straightforward integration of digital I/O signals between field devices and the central controller or interposed wiring harness in industrial automation systems.
