This audio frequency switched relay board will activate the onboard relay when the module detects the user-set input frequency from 2 KHz -15 KHz.

The trigger frequency can be adjusted from 2 KHz -15 KHz using the onboard trimmer. The input voltage range is 100mV to 3V peak to peak.

The oscillator is very stable and has a maximum detection frquency deviation of just ±150 Hz when used with a high quality stable power supply. Switch mode supplies are not recommended.

An LED indicates that the relay is in operation. The board is reverse polarity protected. Screw terminal blocks for all connections.
