RBFU 1.02 Field Unit

Retrofit field unit for 1 fire damper
connects 1 fire damper to the Bustec Ringbus
provides a terminal connection for the Belimo BF230.., BFG230.. and BLF230.. actuators
has a predefined address (no addressing required during system commissioning)
AC 230 V mains power

Description

RBFU 1.02 Field Unit is used for controlling one Belimo 230 V fire damper actuator (BF230.., BFG230.., BLF230..). The unit is connected to the ringbus master controller module 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 1.02 Field Unit is able to work without 230 V, but then it is only sending data about actuator position to Ringbus master controller and is not able to turn on/off the actuators.
