The Allen-Bradley 1492-IFM20F-120-2 Interface Module is a 20-point fusible digital interface module (IFM) for the 1492 wiring system, designed for DIN-rail mounting in industrial control panels. This 1492 IFM uses five 20 mm fuse clips to protect each input line and is rated for operation on 120 V AC supply with an input range of 85–132 V AC, supporting 120 V AC/DC signals for connected devices. The module provides 20 field-side terminals for digital inputs, serving as the interface between sensors or switches and the 1492 system to enable straightforward wiring, isolation, and fault management within the control panel.
