Using the 4 way 817 optocoupler, to achieve the control signal and control signal isolation, you can directly use the microcontroller or other devices IO port to achieve voltage isolation, you can achieve a small voltage regulation, the control side can be an external transistor MOS tube or different voltage levels of the device interface

Driving Port Signal voltage: 3.6-24V
Output port voltage port: 3.6-30V
Jumper Cap can achieve output port is high potential or pull output down
Onboard 4-Channel 817 Are Independent: Can achieve different voltage regulation at the same time
