Allen-Bradley 1492-IFM20D120-2 Interface Module

The Allen-Bradley 1492-IFM20D120-2 Interface Module is a 20-point digital interface module (IFM) in Rockwell Automation’s 1492 family, designed to connect 120 V AC digital field devices to a control system. It provides 20 digital I/O channels with built-in 120 V AC LED indicators for per-channel status and includes extra terminals for outputs to simplify field wiring in compact control panels. The -2 variant is configured for 120 VAC operation and is designed for easy DIN-rail mounting, enabling straightforward integration into standard industrial enclosures. Typical applications include wiring for sensors, limit switches, pushbuttons, and other 120 VAC industrial devices that require reliable digital signaling and visible channel status to aid commissioning and troubleshooting. With its 20-channel footprint and readily accessible indicators, the 1492-IFM20D120-2 offers a compact, package-friendly solution for expanding a Rockwell Automation control system’s digital I/O in environments where 120 VAC devices are prevalent.
