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 eight channels. Great for use in noisy circuits where signal lines require electrical isolation
- Input voltage 3.6V to 24V
- Output voltage 3.6V to 30V
- Jumper switches output from high to low
- Both channels are independent and can be used with different voltages at the same time
