8 Channel Optocoupler Isolation Board For 220V AC Detection, PLC And MCU Interface, Voltage Level Converter, Plug And Play Isolation Module, Ideal For Industrial Control And DIY Prototyping

8-Channel Optocoupler Board for 220V AC Detection
✔️ 8-channel AC input detection with TTL outputs; 1 x board

This 8-channel optocoupler isolation board detects 220V AC presence on each channel and converts it to TTL level signals suitable for PLCs and MCUs. It provides galvanic isolation for safer, cleaner interfacing in industrial control systems and DIY prototyping.

✅ 8-channel 220V AC input detection with TTL outputs (3-5V)
✅ galvanic isolation via optocouplers for safe high/low voltage separation
✅ direct PLC interface with 24V compatible input signals
✅ compact PCB with screw terminals for reliable cabinet wiring
✅ low voltage DC supply 3-5V required for operation
✅ package: 1 x Optocoupler Isolation Board
