Proteus Library : Arduino Relay Modules for Proteus

A relay module is an electronic device that consists of a relay, which is an electrically operated switch, and additional components such as a control circuit, driver circuit, and sometimes an optocoupler. The main purpose of a relay module is to control high-voltage electrical devices or systems using a low-voltage microcontroller, Arduino, Raspberry Pi, or other similar control circuits.


Relay modules are widely used in various electronic projects, automation systems, and IoT (Internet of Things) applications. They provide a safe and efficient way to control high-power devices without exposing the low-voltage control circuit to the risks associated with high voltages.
Common applications of relay modules include controlling lights, motors, heaters, and other electrical appliances in home automation, industrial automation, and robotics projects. They are valued for their ability to interface between microcontrollers and high-power electrical devices, providing a level of electrical isolation for added safety.

Introducing the Relay Modules Library

The Relay Modules Library for Proteus is a comprehensive collection of relay modules designed to seamlessly integrate with various microcontrollers available in Proteus. This library simplifies the simulation of circuits involving relays, making it easier for developers to validate their designs in a virtual environment.

What is Proteus?

Proteus is a popular simulation software that aids engineers and developers in designing, testing, and debugging electronic circuits. With its user-friendly interface and extensive component library, Proteus is widely used for simulating microcontroller-based projects.

The Need for Relay Modules in Simulation

Relays are crucial in control circuits, enabling the control of high-power devices through low-power microcontrollers. In real-world applications, relays play a vital role in automating processes, and their simulation is essential for accurate testing and debugging.

How to Get Started

Simply download and install it to start using the relay modules in your simulations. The download link is provided in the post below. Integrating the Relay Modules Library into your Proteus projects is a straightforward process. With just a few clicks, you can add relay modules to your circuit and simulate their interactions with other components.

Open the Relay Modules Library .zip file, and you will find two folders inside:

1. LIB
2. MODELS

Identify the Proteus library folder on your computer. The default location for the library folder depends on your Proteus software version. For instance, in Proteus 8 Professional, the library folder is typically located at:
C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\DATA\LIBRARY



Once you are in the Proteus Library Folder, paste the files from the LIB Folder (which is from the Relay Modules Library Zip file) into this folder.
Now, go to the Proteus Model folder, which you can locate in the same place as the Library Folder:
C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\DATA\MODELS




Once you are in the Proteus Model Folder, paste the files from the MODELS folder (which is also from the Relay Modules Library Zip file) into this folder.
After adding these files, restart Proteus, and you will find all Relay Modules in the Pick Device Window.
