PC817 4 Channel Optocoupler Isolation Module | 4-Channel Signal Isolation Board 3.6-24V Input 30V Output

PC817 4 Channel Optocoupler Isolation Module | 4-Channel Signal Isolation Board 3.6-24V Input 30V Output 

The PC817 4 Channel Optocoupler Isolation Module is designed to provide electrical isolation between control circuits and high-power circuits. This module uses four PC817 optocouplers, allowing safe signal transmission while protecting sensitive devices from voltage spikes and electrical noise.

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