VCC: Connect the positive pole of the power supply (supply by relay voltage)
GND: Connect power supply negative pole
IN: Relay Module Signal Trigger (High Level Trigger is Effective)
Meaning of high level and low level:
High-level trigger refers to a trigger mode connected with the trigger terminal by the positive voltage of the VCC terminal. When the trigger terminal has a positive voltage or reaches the trigger voltage, the relay sucks.
Low-level trigger refers to a trigger mode connected with the trigger terminal by the negative voltage of the GND terminal. When the trigger terminal has a voltage of 0V or a voltage low enough to trigger, the relay sucks.
Relay contact capacity: 250V 10A (AC) or 30V 10A (DC) (theoretical maximum load capacity)
It is recommended that the AC power be less than 1500W and the DC power be less than 200W.
