Allen-Bradley 1492-IFM40F-F24-2 Fusible Interface Module

Allen-Bradley 1492-IFM40F-F24-2 is a 40-point isolated fusible digital interface module from the 1492 Wiring System. It provides a fixed 40-pin field terminal interface and uses 5 x 20 mm fuse clips to protect each I/O channel, with built-in 24V AC/DC operation and LEDs that indicate blown fuses for quick fault diagnosis. This fusible IFM mounts on a DIN rail and connects to an I/O module through pre-wired 1492 cables, enabling pre-engineered, plug-and-play field wiring between the controller and sensors or actuators. It includes extra output terminals to simplify wiring when expanding digital I/O blocks, and its on-board LEDs help distinguish field-side faults from controller-side issues. As part of the Allen-Bradley 1492 Wiring System, the 40-point module provides isolation between field wiring and the control circuitry, improving reliability in industrial environments that require per-channel fuse protection and clear visual status indicators. Typical applications include machine automation, conveyors, and process-control networks that rely on 24V I/O and pre-wired cabling for rapid deployment and clear fault visibility.
