B&R Industrial Automation (a Business Unit of ABB) X20CHB8880
X20cHB8880: 2x / 4x / 6x Fast Ethernet hub; Modular construction; Easily expandable; The X20 hub is a device that can be used universally in standard Ethernet networks or POWERLINK networks. It is suitable for 100 Mbit/s (Fast Ethernet) networks.; The bus modules expanded to the left allow connection of up to 2 hub expansion modules in addition to the hub base module. This means that a single base device provides up to 6 hub interfaces.
