Module Interface Specifications:

• DC+ : DC power supply positive pole
• DC- : DC power supply negative pole
• IN : Signal triggering pin
• JD+ : Relay control voltage positive
• JD- : Relay control voltage negative
• DC+ and JD+ shorted by jumper cap, DC- and JD- shorted with jumper cap, it is the same voltage between trigger terminal and relay control terminal
• High and low level trigger mode selection. Jumper and L pin connection, IN pin is low level trigger Jumper and H pin connection, IN pin is high level trigger
• Normally closed pin (NC) : relay normally closed pin
• Common pin (COM) : relay common pin
• Normally opened pin (NO) : relay normally opened pin
