Specifications: Working voltage: DC5V/12V/24V Working current: Frequency range: 20Hz-400Hz Output mode: switching signal output Humidity: 0-95% RH Size: 4.4x3.8cm/1.73x1.5" Interfaces: VCC: Positive; GND: Negative; NO: Normally open, NO and COM are disconnected before the relay is closed, and short circuit after the relay is closed COM: common, relay common interface; NC: Normally closed, NC and COM are shorted before the relay is closed, and disconnected after the relay is closed Instructions: 5A Over-current protection Sensor moduleuses current transformer to collect the AC signal to achieve the relay over-current signal output within 0-5A. 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 connec
