The Allen-Bradley 1492-IFM40F-FS24-2 is a 40-point isolated fusible digital interface module (IFM) in the 1492 wiring family, designed to provide protected digital I/O through a fixed-terminal block. It uses five 20 mm fuse clips and 24V AC/DC blown‑fuse indicators to simplify fault diagnosis, and field-side terminals are arranged two per I/O connection for interfacing to digital I/O from 16 to 32 points. The unit is powered from a 24 V AC/DC supply and includes extra terminals for outputs, with Mexico as its country of origin and Rockwell Automation listing it as an active product in the 1492 family.
