The active relay control has its own red LED. A green LED indicates the status of the VCC operating voltage. The control transistor (PNP) has a one kilo-ohm base resistor. Relay is with 10A rating. Relay coil operating voltage 5VDC. Control is by connecting the INx pin to the GND pin. The relay switches its state and the red LED lights up. The total current flowing through the pin is about 4mA. The total current when the relay is energised is about 80mA@5V.
Note! Not for professional use. Do not use this device to operate mains voltage devices. Only for voltages under 50VAC/DC.
