Allen-Bradley 1492-IFM40F-3 Digital Interface Module

Allen-Bradley 1492-IFM40F-3 Digital Interface Module is a 40-point feed-through digital interface module (IFM) designed for the 1492 Programmable Controller Wiring System, featuring a fixed terminal block for field wiring and 3-wire sensor inputs. The 3-Wire Sensor Type Inputs designation indicates this model supports sensors wired in a three-wire configuration, with all 40 input points routed through the module to the compatible 1492 I/O backplane. This module provides a dense, field-wiring solution for digital sensing in industrial control panels, enabling straightforward integration of numerous sensors with Rockwell Automation controllers. It is explicitly described as a 40-point feed-through digital IFM in Rockwell’s product details and is listed with a fixed-terminal-block, 40-point, feed-through configuration by third-party suppliers familiar with the 1492 family.
