B&R Industrial Automation X20IF2772 Communication Interface Module

The X20IF2772 is a two‑CAN bus communication interface module for B&R’s X20 fieldbus I/O system, designed to extend an X20 CPU with robust CAN networks and data transfer rates up to 1 Mbit/s. It provides two CAN bus interfaces via a 5‑pin male multipoint connector for IF1, supports terminating resistors, and includes status indicators for module activity and data transfer. The module carries B&R ID code 0x1F25, consumes about 1.2 W of power, and is rated for hazardous locations (ATEX Ex nA nC IIA T5, Zone 2 II 3G) with an IP20 enclosure. Operating temperature ranges from 0 to 55°C and humidity up to 100%, with vibration tolerance at 4 g. Max CAN bus distance is listed up to 1000 m, enabling long‑reach CAN networks in industrial environments. As part of the X20 family, X20IF2772 integrates with Automation Studio projects to connect CAN devices and subsystems to a B&R controller, supporting ongoing diagnostics and module status monitoring to help identify bus faults quickly. This interface module is suitable for applications requiring reliable CAN connectivity in automation systems, including CANopen‑type or CAN‑based subsystems, where compact form factor and certified safety enclosures are important.
