Allen-Bradley 1492-IFM40F Interface Module

Allen-Bradley 1492-IFM40F Interface Module is a 40-point digital interface module in the 1492 Programmable Controller Wiring System, providing direct 40-point feed-through I/O connections between field devices and the controller via a fixed 40-pin terminal block. It offers variants including 3-wire sensor inputs (1492-IFM40F-3) and isolated fusible configurations (1492-IFM40F-F, 1492-IFM40F-F-2), with options such as 120V AC/DC blown fuse indicators in FS120-4. These modules are used to connect field I/O to Allen-Bradley 1492 wiring systems and are documented in Rockwell’s 1492 literature as standard digital interface Modules with fixed terminal blocks and field-side wiring terminals per I/O connection.
