• AC Voltage Detection: This 8 channel board detects the presence of 220V AC power, outputting a corresponding logic level signal for each channel to your plc or mcu.
• Signal Isolation: Optocouplers provide galvanic isolation between the high voltage ac input and your low voltage control circuit, enhancing system safety.
• Direct Plc Interface: The board outputs a compatible signal for plc digital inputs, allowing for simple integration into industrial automation systems.
• Compact Pcb: The module features a compact pcb layout with screw terminals for reliable connections in control cabinets or prototyping setups.
• Wide Input Voltage: The isolation board operates on a low voltage dc supply typically 3 to 5V, making it suitable for use with microcontrollers and logic circuits.
