A relay is an electrically operated switch. It uses a small, low-power signal from a microcontroller to control a much larger electrical load, effectively acting as a bridge between the logic world and the real world. Modern relay modules often include , which provides electrical separation, protecting your delicate microcontroller from potentially damaging voltage spikes.

A is a specialized simulation tool that allows engineers and hobbyists to test multi-load control systems before physical assembly. By integrating this library, you can simulate an Arduino or other microcontroller switching four independent high-voltage circuits using a single virtual module. What is a 4-Channel Relay Module?

Repeat COM2/NO2/NC2 for channels 2,3,4.

Place your components onto the workspace and make the following connections:

Contains the cataloging indexes for the component search tool.

In simulation, we often ignore the heavy AC load but must accurately model the switching behavior and the inverted logic.

Often supports both High-Level (5V) and Low-Level (0V) logic triggers via onboard jumpers. : Each relay can handle loads up to 10A at 250VAC or 30VDC

Functional Description A typical 4-channel relay module integrates four identical relay circuits, each containing:

Many modules feature optical isolation to protect the microcontroller from back EMF.

Connects to the common terminal by default when the relay is off.
