VCC: pick the anode of 12 v power supply.
GND: connect the cathode of 12 v power supply.
IN1 – IN8: signal trigger side, low level effectively.
COM1- COM8: relay public interface.
NC1 – NC8: relay normally closed interface, relay connect the COM sub before and off, dangling after and off.
NO1 – NO8: relay normally open interface, relay dangling before and off,connect the COM sub after and off.
