Isolation Module PC817 – 2 Channel Optocoupler

Description

ADIY PC817 2 Channel Optocoupler Isolation Board. Onboard with 4-Channel PC817 are independent, so they can achieve different voltage control at the same time. Using 4-way PC817 optocoupler, to achieve the control signal and the control signal isolation, you can directly use the microcontroller or other devices IO port to achieve the voltage isolation control, you can achieve a small voltage control, the control side can be an external transistor MOS tube or different voltage levels of the device interface.
