Allen-Bradley 1492-IFM40F Fiber Optic Interface Module

Allen-Bradley 1492-IFM40F is a 40-point digital interface module (IFM) used in the 1492 wiring system to connect multiple digital sensors and switches to Rockwell Automation controls. The 40F family includes variants such as F24AD-4 (40-point fusible digital IFM with 24 V inputs, 5 x 20 mm fuse clips and 4 terminals per input) and FS120-4 (40-point isolated fusible digital IFM with 120 V AC/DC indicators, 5 x 20 mm fuse clips and 4 terminals per input), reflecting options for different supply voltages and protective configurations. Other versions describe 40-point configurations with extra output terminals or feed-through arrangements, such as 1492-IFM40F-F-2 and 1492-IFM40F-F-3, each catering to specific input wiring schemas and sensor types while maintaining the same 40-point footprint.
