Allen-Bradley 1492-IFM40F-3 Digital Interface Sensor Module

The Allen-Bradley 1492-IFM40F-3 Digital Interface Sensor Module is a 40-point feed-through digital interface module (IFM) for the Allen-Bradley 1492 wiring system, providing 40 digital input points with 3-wire sensor inputs. It employs a 40-pin fixed terminal block and accepts sensor voltages from 0 to 60 V AC or DC. As part of the 1492 Digital Interface Modules family, it serves as the digital input interface within a 1492 I/O network, enabling direct connection of three-wire sensors to the controller's wiring system. This configuration is suitable for industrial automation tasks where multiple sensors must be brought into a single digital I/O network with minimal wiring complexity.
