3-Channel 220V AC Optocoupler Isolation Detection Module
The 3-Channel 220V AC Optocoupler Isolation Detection Module is a compact interface module designed to detect the presence of 220V AC voltage and provide isolated logic-level output signals to a microcontroller, PLC, Arduino, or other control system. It uses optocoupler-based isolation to electrically separate the high-voltage AC input from the low-voltage control circuit, helping improve system safety and signal reliability.
Featuring three independent AC detection channels, the module can monitor up to three separate 220V AC signals simultaneously. Each input channel provides an isolated detection output, making it suitable for monitoring AC mains status, switches, relays, contactors, appliances, and other AC-powered equipment.
