PC817 2-Channel Optocoupler Isolation Module

The PC817 2-Channel Optocoupler Isolation Module is a compact PCB designed to provide electrical isolation between input control signals and output circuits. It features two PC817 optocouplers for dual-channel isolation, enabling safe interfacing between high-voltage or noisy circuits and sensitive microcontrollers.

This module is suitable for microcontroller interfacing, relay triggering, industrial automation, and protection of low-voltage electronics from high-voltage spikes. The dual-channel design allows independent isolation for two separate signals.
