Allen-Bradley 1492-IFM20F A Digital Interface Module

Allen-Bradley 1492-IFM20F A Digital Interface Module is a 20-point feed-through digital interface module in the 1492 Programmable Controller Wiring Systems. This standard-terminal IFM provides a direct interface for digital field devices such as sensors and switches, enabling 20 discrete signals to be wired through the unit to the 1492 I/O system. The 'IFM' designation identifies it as a Digital Interface Module used to connect field devices to the 1492 wiring architecture, and the '20F' indicates twenty field terminals configured for feed-through wiring. The product line includes variant models to support different sensor types and voltages, such as 1492-IFM20F-F24-2 (a 24V variant) and 1492-IFM20F-2, as well as 1492-IFM20F-3 for 3-wire sensor inputs, reflecting the range of wiring options available for digital input configurations. As part of Allen-Bradley's Rockwell Automation ecosystem, this module is designed to integrate with the 1492 family’s standard terminal approach and is intended for use in industrial automation applications where a compact digital interface for multiple sensors or switches is required, enabling straightforward field wiring and compatibility with existing 1492 wiring system components.
