FC – RB
Three speed fan and valve actuator driver

D E S C R I P T I O N
The FC-RB is a three speed fan and thermic valve actuator driver. It accepts 0 – 10 V signals for control of 230 V AC fans through its electromechanical relays and valves through its solid state relays. It was designed as Codis 35 FC expansion module but it can be used as a stand alone device.

FC – RB
FC-RB is used in fan coils and floor convectors which have three speed 230 V AC fans and thermic valve actuators. Its small size makes it ideal for space limited apllications and it offers two differnet possibilities for mounting: DIN rail clip and direct screw mounting.
