Description
2x / 4x / 6x Fast Ethernet hubModular constructionEasily 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.
