Relay pull while over-current, relay released while not over-current. Users can use the relay COM, NC, NO three ports to control the external circuit on and off, in order to achieve over-current protection. Use the potentiometer to set the overcurrent protection point, the clockwise adjustment reduces the detection current. 1. Measured the wire through the current transformer, connect VCC and GND to DC12V power supply. 2. Adjust the potentiometer, when you hear the sound of the relay pull (can be measured with a multimeter COM and NO whether was turned on, if connected to the relay means activated), then reduce or cut off the current flowing that through the tested wire , if the relay release at this time that over-current protection point has been identified (available to multimeter COM and NC measurement whether is connected, if connected to the relay means been released). 3. When reduce or cut off the current flowing through the wire , the relay is not released, will still need to continue to adjust the potentiometer to find the over-current protection point. Package included: 2 x AC Current Sensor Relay Modules (5V 12V 24V Optional, you will get the two SAME ones, not mixed types.)
