B&R X20 System distributed control and I/O topology. Built on a unique 3-part modular architecture (terminal block, electronic module, and bus module), the X20 series enables toolless pre-wiring and full hot-swapping under power to minimize machinery downtime. It delivers dense packaging with up to 12 channels per 12.5 mm slice, drastically reducing control cabinet footprint. Operating over deterministic networks including POWERLINK, EtherCAT, and Modbus TCP, the system yields microsecond-level synchronization while seamlessly integrating standard I/O, specialized motion technology, and functional safety via openSAFETY into a unified automation platform.
