Fan Speed Relay Module – 24Vac




The IO-FRM3 is an interlocked, three relay module. Intended for use as a fan speed switch, the unit can be used to change fan speeds on fan motors with multi-tapped windings and also transformer speed controlled motors. The ‘change-over’ design of the relay contact configuration and common switching point ensure that only one set of contacts is active at any one time, thus preventing short circuits. Versions are available with 230Vac or 24Vac coils,  DIN rail mounting.
