DC+: Input the positive pole of the DC power supply2.DC-: Input the negative pole ofDC power supply3.IN+: Positive signal input terminal4.IN-: negative signal input terminal5. NO: Relay normally open interface, the relay is suspended before it is closed, and shorted to COM after it is closed6.CO: common interface of relay7. NC: Normally closed interface of the relay, the relay is short-conmected with CO before it is closed, and it is suspended afterbeing closedButton trigger. (positive trigger: DC- and in- short-circuit, DC+ and IN+ are conmected to the button)Or. (Negative trigger: DC+ and in+ are short-circuited, DC- and IN- are connected to the button)
