The 3 Channels AC 220V Optocoupler Isolation Test Board Module from Riuulity is designed for secure signal transmission and voltage detection in industrial control systems. It isolates high-voltage AC signals (220V) using optocouplers, converting them into safe TTL signals (3–5V) readable by microcontrollers or PLCs. With stable NPN output and indicator LEDs for real-time status monitoring, it ensures safe, accurate signal detection and reliable performance. Compatible with 24V PLCs and microcontrollers, it simplifies integration across various automation systems. Made with high-quality PCB materials, it ensures durability and long-term stability in harsh environments. Ideal for safety-critical AC power detection tasks.
