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
Connection
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.
