✅ Product introduction
◉The module collects AC signals by current transformer to realize the output of relay signals after overcurrent within the range of 0-5A.
◉When the relay is over current, it closes, and when the relay is not over current, it is released.
◉Users can use the three ports of the relay, COM, NC and NO, to control the connection and disconnection of the external circuit, so as to realize the over-current protection.
✅ Product Parameters

◉Working environment: -40°C~+85°C. 0-95%RH
◉Current detection range: AC0.3-5A
◉VCC: positive pole of working voltage;
◉GND: Working voltage negative;
◉and short connect after the relay is pulled out; ON: Normal start, NO and COM are disconnected before the relay is pulled out,
◉COM: Common end, relay public connection;
◉NC: Normally closed end, NC and COM are short connected before the relay is pulled in, and then disconnected;
✅ Method of use
◉The overcurrent protection point is set by adjusting the potentiometer, in which the detection current is reduced by clockwise adjustment.
✅ Here's how:
◉Connect the measured conductor through the current transformer, VCC and GN D to the DC5V power supply;
◉Adjust potentiometer, when heard the sound of the relay and (available multim eter measuring whether COM and NO get through, if connected to relay has been attracting), to reduce the current through the conductor being tested or cut off, if the relay over-current protection point has released specifications for (use multimeter measure COM and NC is switched on, if through to relay has released).
◉If the relay is not released while reducing or cutting off the current flowing t hrough the measured wire, it is necessary to continue to adjust the potentiometer to find the overcurrent protection point.
