When do you need it?
You will use this module when you need isolation control and voltage converter.
1.Driving Port Signal Voltage:3.6-24V
2.Output Port Voltage range: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 the same time
4, 4 channel 817 onboard is independent, which can realize the simultaneous control of different voltages.
The input port is shared with GND;
The output ports are independent of each other;
It is optocoupler output.
V and G will be connected after input valid signa in input port.
