B&R Industrial Automation X20BB82 Bus Base With End Covers Included

X20BB82 is a B&R X20 bus base for the X20 System that provides a backplane with two expansion slots to host two X20 add-on modules, enabling flexible growth of I/O and control within a single chassis. It is designed to sit behind a base module (BC, HB, etc.) and an X20 power supply module, with two expansion slots ready to accommodate two X20 add-on modules (for example IF and HB). The delivery includes left and right end cover plates to finish the enclosure, specifically X20AC0SL1 and X20AC0SR1. This backplane configuration supports a compact, modular approach to expanding an X20 installation without duplicating primary power or base components, aligning with B&R’s modular automation philosophy and the broader X20 System architecture.
