4-Channel Optocoupler Isolation Module - PC817

This is a PC817 4 Channel Optocoupler Isolation Board. Onboard with 4-Channel 817 are independent, so can achieve different voltage control at the same time. Using 4-way 817 optocoupler, to achieve the control signal and the control signal isolation, you can directly use the microcontroller or other devices IO port to achieve 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.

This is a board designed for opto-isolation, helpful for connecting digital systems (like a 5V microcontroller) to a high-voltage or noisy system.
