Description

RBFU 1.10 LE Field Unit is used for controlling up to two Belimo 230 V fire damper actuators (BF230.., BLF230..). RBFU 1.10 LE Field Unit is connected to RingBus master controller via the 4 wire Ringbus communication. Each unit has a predefined address and therefore has not to be addressed during the system commissioning. RBFU 1.10 LE Field Unit is able to work without 230 V, but then it is only sending data about actuator position to the Ringbus master controller and is not able to turn on/off the actuators.
