1. digital input port, you can connect with GND or 12V, actually, you just let input port short with GND or not short with GND. Not need input any voltage. if you want to input voltage, MAX support dc12v.
2. 5v can be used, if <4v , means logical "0", if you use 5V means logical "1".
3. input MAX is 12v, if use 15v will be not good for long time, suggest connect a resistor in series to reduce voltage.
