This audio frequency switched relay board will activate the onboard relay when the module detects the pre-selected input frequency from 150Hz to 2KHz.
The trigger frequency can be adjusted from 150Hz to 2KHz using the onboard trimmer. The input voltage range is 100mV to 3V peak to peak.
An LED indicates that the relay is in operation. The board is reverse polarity protected. Screw terminal blocks for all connections.
