The triode drive increases the relay coil and controls the high impedance of the foot. The control pin has a pull-down circuit to prevent the floating relay from malfunctioning. How to use it: Just connect a digital output of your arduino to your relay module, and you can control a power-demanding appliance with the digital signal provided by your arduino.
