B&R Industrial Automation X20HB2880 IO Module

The X20HB2880 hub expansion module from B&R is a dedicated component of the X20 IO system that provides an integrated two-port hub for expanding an existing X20 hub network. It features two RJ45 connectors and is designed to be installed in compatible X20 hub slots, extending the PowerLink-based I/O topology without introducing a separate hub controller. As part of the X20 hub expansion family, the module supports daisy-chaining and reliable interconnection of additional X20 I/O slices and interface modules, helping to scale a control system in compact machinery, packaging lines, or automated manufacturing setups. Typical applications include enlarging an X20 IO rack to accommodate more sensors and actuators within a single PowerLink network. In practice, the X20HB2880 is used alongside other X20 components such as bus controllers and interface modules to build modular, scalable control architectures that preserve deterministic communication between devices. With its built-in two-port hub and standard RJ45 interfaces, the X20HB2880 enables straightforward expansion without additional cabling complexity.
