Request QuoteAllen-Bradley 1492-IFM40F-FS120-2 — The Allen-Bradley 1492-IFM40F-FS120-2 is a 40-point fusible-isolated digital interface module (IFM) with two fuses per input/output point and 120V AC/DC blown-fuse indicators. The “FS120-2” designator indicates 5 × 20 mm fuse clips with 120V-rated blown-fuse indicator LEDs and two fuses per circuit. Each point has individual isolation and includes extra terminals for parallel output wiring or daisy-chained field devices, reducing the need for separate terminal blocks. The 1492-IFM40F family is designed for direct plug-in wiring of Allen-Bradley PLC / ControlLogix / CompactLogix I/O modules via pre-wired cables (1492-CABLE series), eliminating the need for panel-mount terminal strips while providing per-channel fusing and fault indication.
