Key Features:
- AC Voltage Detection: Detects 220V AC presence and converts it to a TTL output signal
- Optocoupler Isolation: Provides safe electrical isolation for microcontroller and PLC systems
- Wide Power Supply Range: Operates on 3V – 5V for MCUs and 24V for PLCs
- Easy Integration:
- Green 2P terminal (5.0mm): Connects to 220V AC input
- 3P terminal: Outputs signal for microcontroller detection
- Compact Design: 73mm × 15mm, suitable for embedded applications
How It Works:
- When 220V AC is present, the output provides a TTL signal, allowing a microcontroller or PLC to detect voltage presence.
- For PLC integration, connect COM (24V) to power, OUT to PLC input, and GND to negative terminal.
