The X20BC0143-10 is a B&R X20 bus controller that connects CANopen networks to up to 253 X2X Link I/O modules, enabling scalable remote I/O within cabinet installations. It provides a single CANopen interface over a 9‑pin DSUB connector and is designed for the X20 system’s cabinet I/O topology, with expansion achieved by adding X2X Link I/O modules. For cabling, order the DSUB CANopen connector (7AC911.9) separately, and use B&R Automation Studio for configuration and diagnostics of the bus parameters and I/O mapping.
