4-Channel Optocoupler Isolation & Level Converter Module, 3.3–24V Input to 3–30V Output

4 CHANNELS. ISOLATION + LEVEL CONVERSION. ONE COMPACT MODULE.

The amiciTech 4-Channel Optocoupler Isolation & Level Conversion Module is designed for applications where you need to isolate control signals and convert between different voltage levels.

With four independent channels, the module can handle separate digital, pulse or logic signals while providing photoelectric isolation between the input and output sides.

OPTOCOUPLER-BASED ISOLATION

Each channel uses an 817 series optocoupler to provide photoelectric isolation between the input and output sides.

This helps separate the control circuit from the output circuit and provides anti-interference functionality for compatible applications.


WHY USE THIS MODULE?

If your project involves different control voltages, signal isolation or interfacing between separate control circuits, this module combines both functions in a single board.

It can be used for signal interfacing with:

MCU • PLC • Arduino • Sensors • Inverters • Motor-Control Systems
