Allen-Bradley 1492-IFM40F-FS120-4 USNT Interface Module

Allen-Bradley 1492-IFM40F-FS120-4 USNT is a 40-point isolated fusible digital interface module (IFM) designed for Rockwell Automation's 1492 wiring systems. It connects to digital I/O modules via a 40-pin cable header and provides four terminals per output, using 5 x 20 mm fuse clips to provide individual protection for each channel; the module is rated for 120 V AC/DC and includes blown fuse indicators for rapid fault diagnosis. By delivering isolated protection across all I/O points, this digital interface module supports safe expansion of PLC I/O networks in industrial automation applications such as machine control, packaging lines, and process automation.
