Allen-Bradley 1492-IFM40F Limit Switch Snap Action

Allen-Bradley 1492-IFM40F is a 40-point digital interface module (IFM) in the 1492 wiring system. It provides a fixed 40-pin terminal block for I/O connections and four field-side terminals per I/O connection, enabling straightforward wiring of digital sensors, switches, and actuators to Allen-Bradley PLCs via pre-wired digital interface cables. This module is categorized as a digital interface module with a fixed terminal block and is part of the 1492 connection devices family (Bulletin 1492-connection devices). The 1492-IFM40F family includes variants such as 1492-IFM40F-F24AD-4 (24V AC/DC) and 1492-IFM40F-FS120-4 (120V AC/DC), preserving the 40-point interface while accommodating different supply voltages and fuse configurations. The cable connector pin type is designed for interfacing to digital I/O from 16 to 32 points, and four field-side terminals are provided per I/O connection to simplify field wiring.
