B&R Industrial Automation X20IF2772 IO Module

The B&R X20IF2772 is a two-CAN-bus interface module for the X20 system that adds dual CAN network connectivity to a B&R CPU, delivering up to 1 Mbit/s data transfer and enabling reliable CAN communications across field devices. It provides two CAN interfaces (CAN bus 1 and CAN bus 2), each accessible via a five-pin male multipoint connector, with a maximum cable distance of 1000 meters. The module draws about 1.2 W of power and is rated IP20, with an operating range of 0 to 55°C and humidity up to 100%. It carries multiple international certifications, including CE and UL/cULus, plus hazardous-location approvals (ATEX Zone 2, II 3G Ex nA nC IIA T5 Gc IP20) and cCSAus; the B&R X20 bus ID code is 0x1F25. LED indicators provide feedback on module status, data transfer, and terminating resistor state to aid diagnostics. Typical applications include expanding a B&R X20 CPU to connect CAN-enabled devices, sensors, and actuators in machine automation, robotics, and distributed control networks.
