PC817 2-Channel 3.6V-30V Optocoupler Isolation Board Voltage Converter ModuleProduct Highlights

Voltage Isolation:Provides complete electrical isolation between input and output circuits, protecting your microcontrollers (like Arduino, ESP32, Raspberry Pi) from potentially damaging voltage spikes or ground loops.
Wide Voltage Range:Operates with input voltages from 3.6V to 24V and output voltages from 3.6V to 30V, making it compatible with a variety of sensors, actuators, and power supplies.
Dual Channel:Features two independent channels, allowing you to isolate and convert two separate signals simultaneously. Use different voltages on each channel!
Onboard LED Indicators:Each channel has an LED indicator that illuminates when the input signal is active, providing visual response for easy troubleshooting.
Selectable Ground Connection:Each channel includes a jumper that allows you to connect or disconnect the input and output grounds, providing flexibility for different isolation requirements. Remove the jumper for full 24V industrial sensors with 5V or 3.3V microcontrollers.
Isolating noisy signals in sensitive circuits.
Protecting microcontroller inputs from high-voltage sources.
General-purpose voltage level and protect your sensitive circuits with this versatile 2-Channel PC817 Optocoupler Isolation Module! This module provides a reliable and efficient way to convert input signals from one voltage level to another while maintaining complete electrical isolation. Perfect for a wide range of applications, from industrial automation to hobbyist electronics projects.

Important Notes:

The PC817 optocoupler has a limited output current of 50mA. If your output circuit requires more than 50mA, you will need to use a transistor or other suitable driver to provide the necessary current. Do not directly connect high-current devices like motors to the optocoupler output.

⚠️ Not a Replacement for a Mechanical Relay or Switch:

This module\'s output is an electronic (transistor) switch, not a mechanical contact. It\'s designed to isolate and level-shift an active signal between two circuits -- it is not a substitute for a mechanical or reed relay in applications that require simply connecting/shorting two wires together (for example, a radio PTT line, alarm loop, or pushbutton replacement). If your application needs a true switch-like contact closure rather than signal isolation, please choose a mechanical or reed relay module instead.
