Module Interface
Input part
The positive (VCC:connect 5 v power supply according to the relay voltage power supply)
GND:5 v power supply cathode
IN:relay module (effective) low level trigger signal trigger end
High Level and Low Level Meaning
High level trigger refers to using the anode voltage at the VCC connection way of a trigger and trigger the end, when the trigger side has the positive voltage or to trigger voltage when the relay is off.
Low level trigger refers to using the negative voltage at the GND connection way of a trigger and trigger the end, when the trigger side has 0 v low voltage or voltage to can trigger, the relay is off.
