Module Interface Description:
1.DC +: Module DC power supply positive (positive voltage of trigger terminal)
2.DC-: Module DC power supply negative (trigger terminal voltage negative pole)
3.IN: trigger terminal (default trigger voltage is the same as power supply)
4. High / low level trigger mode selection, as shown in the figure, when the jumper is connected to the L terminal, the IN terminal is a low level trigger, and when it is connected to the H terminal, the high level trigger
5. Normally closed end (NC): normally closed end of relay 6. Common terminal (COM): relay common terminal 7. Normally open (NO): relay normally open
