Description:
-8 road relay output module, a maximum relay contact output is 250V / 10A.
-Input IN1 and IN2, IN3, IN4, IN5, IN6, IN7, IN8 signal low level effectively.
-VCC, GND power input end, relay can power input end JD - VCC alone.
Module interface:
-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.
Relay output: there are 12 line interface, all interface can be directly wired to derivation, convenience for the user
-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.
