CATALOGUE NUMBER DESCRIPTION
*5500NB Network bridge DIN rail
The network bridge is a network support device that provides an isolated communications channel between C-Bus
units on separate networks. Both sides of the network bridge are optically isolated, providing electrical isolation between
adjacent networks.
Network bridges are required to manage networks to particular units in particular zones, or to extend the network past
system limitations of 100 passive units and 1000 metres of C-Bus cable in any one network.
