Product Description

Control of one fire or one smoke ring

RBCPU 2.10-LE is an intelligent master controller which controls and supplies 1 fire ring or 1 smoke ring. Up to 100 field units or 200 elements in one ring can be controlled by the RBCPU 2.10-LE, and up to 100 RBCPU 2.10-LE master controllers can be connected in a mid-tier Ethernet network with the Ringbus data server, allowing this system to be implemented even in the largest buildings. Integrated fault state relay 250VAC 2A no/nc Relay is active when no errors in system are detected


RBCPU 2.10-LE is connected to booth ends of the ring by a 4 wire cable and to the power supply by three 3 wire cables.


The ring is isolated from mains by transformer in SMPSs and all RBCPU 2.10-LE control units in the network are isolated between them selves by transformers in Ethernet connectors.
