AC 220V optocoupler detection module uses optoelectronic isolation to detect whether the 220V AC circuit is powered on. It converts the AC existence signal into TTL digital signal for MCU reading. The isolation structure protects your low-voltage control board from high-voltage surge and noise. It is widely used for AC power status monitoring, electrical equipment state feedback, automatic control and alarm systems.
