4 Channel 5V Relay Module info
4 Channel 5V Relay Module can control DC and AC signals including 220V AC load. There is one normally open and one normally closed contact.
4 Channel 5V Relay Module has triode drive which increases relay coil and high impedance controller pins. The module’s pull down circuit avoids malfunction and there are power supply and control indicator LEDs on the board.
