Module Interface Description:
DC +: positive module DC power supply (positive terminal voltage trigger)
DC-: DC power supply module negative electrode (anode terminal voltage trigger)
IN: Signal triggering end (default trigger the same voltage as power supply)
JD +: positive voltage relay control terminal
JD-: relay control terminal voltage of the negative
DC + and JD + with jumpered, DC- and JD- with jumpered, the same trigger terminal and relay control terminal voltage
High and low trigger mode selection, when the jumper is connected to L side, IN terminal is low trigger connection with the H for the high end trigger
Normally closed terminal (NC): relay normally closed terminal
Common terminal (COM): relay common
Normally open (NO): normally open relay
