Smart Relay works as a normal On/Off relay for non-dimmable loads up to 700W, suitable for 6 amp circuit.

The switched circuit can be mains powered or volts free (low voltage). Mains power can also be taken from the Relay itself to power the circuit (see wiring instructions for more information).


Switch Sense Input must be used for 230V AC mains power and must be treated as mains voltage at all times. If using the LP81 with any input below 230v, the peripheral device is at risk.
