Description

RBFU 3.30 has 12 digital outputs. It is mountable on DIN rail. Outputs are NO relay contacts. The unit is connected to the Ringbus master controller via a 4 wire ring bus communication. Each unit has a predefined address and therefore has not to be addressed during the system commissioning. RBFU 3.30 ST unit is able to work without 230 V, but then it is only sending information about its power supply condition and is not able to turn on/off the outputs. Relay outputs will go in to preprogrammed safe state if communication is lost for more than 10s or around 1s after loss of the external power. Possible safe states are CLOSE, OPEN and STAY
