Mechanical properties
Slot Hub expansion for X20BC8084 and X20HB8884
Material number:
  • Active hub expansion module
  • 2x Fast Ethernet hub for redundant wiring
  • Hot-swap-capable

The X20BC8084 POWERLINK bus controller and the X20HB8884 module are equipped with an integrated link selector function. An additional 1 or 2 slots are available, depending on the bus base used. The active X20HB2885 hub expansion module can be operated in these slots.

The active hub expansion module is equipped with one integrated 2x hub and allows redundant wiring. This means that the connection between the two ports remains intact if there is a failure in the bus controller or Compact Link Selector. The status of the module and network are indicated by LEDs.
