PC817 2 Channel Optocoupler Isolation Module | Dual Channel Signal Isolation Board 3.6-24V Input 30V Output

PC817 2 Channel Optocoupler Isolation Module | Dual Channel Signal Isolation Board 3.6-24V Input 30V Output 

The PC817 2 Channel Optocoupler Isolation Module is designed to provide electrical isolation between low-voltage control circuits and high-voltage or noisy circuits. The board uses two PC817 optocouplers, allowing safe signal transfer while protecting sensitive devices from voltage spikes, interference, and ground loop problems.

Each channel works independently, so different voltages can be controlled at the same time. The module can be connected directly to Arduino, Raspberry Pi, ESP32, PLC, microcontrollers, and industrial control boards for reliable I/O isolation.
