Description 4 channel optocoupler isolation module

The 4 Channel Optocoupler Isolation Module provides a safe and reliable way to isolate signals. This compact module protects your microcontroller or control system from voltage spikes and interference. Each channel uses an optocoupler to isolate electrical signals. This keeps your control electronics protected from unwanted electrical influences.

The module is ideal for applications with different voltage levels or interference-sensitive circuits. Think of projects with Arduino, Raspberry Pi or industrial automation. By using optical isolation, you can safely transfer signals without a direct electrical connection. This prevents damage to your main equipment and increases the reliability of the system.

Each input has an LED indicator that shows the status of the channel. This way you can see at a glance which signals are active. The module works with an input voltage of 3.6V to 24V DC. Thanks to the standard connection pins, it is easy to integrate into any circuit or breadboard.

Whether you're working on a hobby project or building a professional system, this optocoupler module gives you control and peace of mind. Compact, powerful and designed with safety as a priority.
