Description
Hub expansion module2x Hub 100 BASE-FX
The POWERLINK bus controller X20BC8083 and the stand-alone hubs X20HB8880 and X20HB8815 are equipped with a modular hub expansion. An additional 1 or 2 slots are available, depending on the bus base used. The X20HB2881 hub expansion module can be operated in these slots. Note that the hardware revision of the X20BC8083 and the X20HB8880 must be ≥F0.The hub expansion module is a 2x hub. The Ethernet connection is made using 62.5/125 μm or 50/125 µm fiber optic multimode cable with a duplex LC connection. The status of the module and network are indicated by LEDs.
