CBus Relays

There is no limit to the overall handling capacity of C-Bus control systems. The C-Bus relay units are C-Bus relay-switching devices designed to be DIN-rail mounted into electrical switchboards or similar enclosures. For maximum control flexibility and energy savings, individual zones are independently controlled. The most commonly specified relay controls are 10A and 20A per channel, but a C-Bus system can easily accommodate all current loads.

C-Bus DIN Rail-Mounted 10A Relays

Part Codes: L5504RVF, L5504RVFP, L5508RVF, L5508RVFP, L5512RVF, L5512RVFP
