Product Introduction:
1. Driving Port Signal Voltage:3.6-24V
2. Output Port Voltage Port:3.6-30V
3. Jumper Cap Can Achieve Output Port Is High POtential Or Pull Down Output
4. Onboard 4-Channel 817 Are Independent:can achieve different voltage control at then same time

NOTE:
The input port is shared with GND;
The output ports are independent of each other.
