12V 8 Channel Relay Module with OptocouplerThis is an 8 channel relay board that runs on 12 volts. Any microcontroller or other control system circuits can be used to control loads rated up to 250V 10A AC directly. Each relay has three connections: Common (C), Normally Open (NO), and Normally Closed (NC), all of which are connected to three pin screw terminals, making it simple to connect and disconnect. To make debugging easier, the board incorporates a power indicator and a relay status LED.

Each relay or channel in a four-channel relay module requires a driving current of 15-20 mA and a 24 volt supply
