Allen-Bradley 1492-IFM40F-FS120-2 Interface Module

The Allen-Bradley 1492-IFM40F-FS120-2 is a 40-point isolated fusible digital interface module (IFM) in the 1492 family, designed to protect and condition digital I/O with built‑in fusing for each point and clear fault indication. It uses a fixed terminal block and provides two field-side terminals per I/O connection for rugged, plug‑in field wiring to sensors and actuators, while offering a 40‑pin interface to digital I/O. The module includes 5 x 20 mm fuse clips and 120 V AC/DC blown fuse indicators, enabling easy visual fault detection without removing components. Its supply is 120 V AC at 60 Hz, and its digital interface is suitable for interfacing to digital I/O from 16 to 32 points via the preconfigured connector pins. Additional terminals are provided for outputs to support broader I/O configurations. This interface module is intended for use in Allen-Bradley control systems to isolate and fuse digital I/O lines, helping protect both the PLC and field devices in industrial automation applications.
