B&R X20HB1882

Hub expansion module 1-port hub, 100BASE-FX Single-mode glass fiber cables Range up to 50 km Hot-swappable The POWERLINK bus controllers X20BC8083, X20BC8084 (starting with revision D0) and the standalone hub X20HB8880 are equipped with a modular hub extension. 1 or 2 additional slots are available depending on the bus base. The X20HB1882 hub expansion module can be operated in these slots. Please note that the hardware revision of the X20BC8083 and X20HB8880 must be ≥F0. The hub expansion module is designed as a 1-port hub. The Ethernet connection is made using 9/125 µm single-mode glass fiber cables with a duplex LC connector. The module state and network status are indicated using LEDs.
