PC817, 4 channel opto-isolator breakout for Arduino optoisolato, optocoupler ST

This module allows you to use low-level signal to control a higher level voltage, for example, 3V or 5V voltage controlling 9V or 12V voltage. It uses the PC817 optoisolator. Comes with four channels. Great for use in noisy circuits where signal lines require electrical isolation

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

5.Features :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
