DIY 8 Channel 12V Relay Module with Optocoupler PLC Relay Controller
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.
