Allen-Bradley 1492-IFM40F-FS120-2 Programmable Logic Controller Module

The Allen-Bradley 1492-IFM40F-FS120-2 is a 40-point isolated fusible digital interface module (IFM) in the 1492 family that provides a protected bridge between field devices and PLC digital I/O. It uses a fixed terminal block and provides two field-side terminals per I/O connection, supporting 40 discrete digital channels in a single module. Five 20 mm fuse clips deliver per-path protection, with blown-fuse indicators to simplify fault isolation. The unit is powered from a 120 V AC supply (60 Hz) and features an isolated in/out configuration to help keep field wiring separate from control circuitry. Additional output terminals are available to accommodate wiring expansions and more complex I/O schemes. Designed for industrial automation environments, the 1492-IFM40F-FS120-2 integrates with Rockwell Automation 1492 connection devices, delivering a robust, fuse-protected digital interface for reliable signaling in control systems.
