Allen-Bradley 1492-IFM20F-2 Interface Module

Allen-Bradley 1492-IFM20F-2 Interface Module is a DIN-rail mounted digital interface module in the 1492 wiring system, acting as the bridge between a PLC I/O module and field wiring via pre-wired cables. The 20F designation indicates a 20-terminal female interface with Standard Terminal connections, and the unit is designed for DIN-rail mounting to simplify panel layouts. It is rated for up to 12 A and supports direct connection through 1492-CAB pre-wired cables that plug into the IFM and I/O modules, eliminating most point-to-point field wiring. As part of the 1492 family, the IFM supports integration with a range of controllers, including ControlLogix, CompactLogix, SLC 500, MicroLogix, and Flex I/O systems, when used with the appropriate 1492 cables and interface modules. This approach—a dedicated interface module plus pre-wired cables—reduces installation time and simplifies maintenance in industrial control panels, while keeping the field connections organized and reliable. The 1492-IFM20F-2 is documented in Allen-Bradley literature as the Standard Terminal variant of the 1492 digital interface modules.
