The 5V single channel relay module with optocoupler is a compact electronic device used to control high-power electrical circuits using low-power signals. It consists of a relay, which serves as an electrically controlled switch, and an optocoupler for electrical isolation between the control circuit and the relay. The module operates at 5V and provides a reliable and safe means of controlling high-power loads.

The optocoupler in this module helps protect the control circuit from voltage spikes, noise, and potential damage caused by the high-power circuit. It achieves this by using an LED and a photosensitive component (usually a phototransistor) to transfer signals optically.

The control signals from a microcontroller or other low-voltage device activate the LED, which then triggers the phototransistor to activate or deactivate the relay.

This type of relay module with optocoupler is commonly used in applications where electrical isolation is crucial, such as industrial automation, home automation systems, or any scenario where the control circuit needs protection from the high-power circuit’s electrical disturbances.
