B&R Industrial Automation X20HB 2880 IO Module

X20HB2880 is a B&R hub expansion module for the X20 hub system. It provides an integrated two-port hub and two RJ45 connectors, enabling the X20 network to be extended across multiple hubs within a single X20 backplane. As a hub expansion, the X20HB2880 interconnects X20 hubs and I/O segments to support modular, scalable layouts in automation installations, typically managed through Automation Studio. This copper-port variant is identified by the part number X20HB2880 and is part of the family that includes a fiber-port option (for example, X20HB2881 with two fiber connectors), making it possible to tailor the topology to copper or fiber infrastructure. The module is designed to fit standard X20 system slots and works alongside other X20 modules and bus controllers to form a cohesive fieldbus network for distributed I/O in industrial environments. Common applications include expanding the reach of a B&R X20 fieldbus network in manufacturing cells, enabling more devices to be controlled with a compact, integrated hub, and organizing larger IO topologies in machines where space and cabling are critical.
