Hoyme-ADP-0241-05A

This Relay Adaptor may be used as an automatic switch having a 24Vac coil and 120Vac contact points to control a line voltage circuit for up to a 5 amp draw. i.e. Exhaust Fan. Adaptor can also be used 100% for 24Vac switching (See ADP-1101). Switching 24Vac Dampers and Thermostat Circuits use 5A type only (ADP-0241-05A). For 120Vac fan control, use 10A type only (ADP-0241-10A).
