Relays are suitable for driving high power electronic devices such as lights, electric fan and air condition. This relay module can be used to control high voltages with a low voltage by connecting to an MCU Controls DC or AC signals – 220V AC load Working voltage: 5v; PCB size: 2.0 x 4.3 cm With power indicator and signal output indicator Working principle: when a high level is given to SIG, the PNP transistor is energized, coil of the relay electrified, and the indicator LED lights up; when a low level is given, PNP will be de-energized, the original state is restored and the indicator LED goes out then
