This comprehensive guide covers the importance of this library, step-by-step installation instructions, and a complete simulation walkthrough using an Arduino Uno. Why Use a Dedicated 4-Channel Relay Library?
Simulating four separate AC loads alongside a microcontroller can overtax your computer's CPU. If Proteus displays a "Simulation is not running in real-time" warning, try reducing the frequency of the AC alternators or closing background applications.
Connect the of your AC Alternator to the Common (COM) terminal of the relay.
Next, search for and place the other components. If using an Arduino, place the ARDUINO-UNO or ATMEGA328P model. Add a from the Optoelectronics or Simulator Primitives category to send commands. Then, add loads that will be controlled by the relays, such as LAMP or MOTOR-DC components, which can be found by searching LAMP or MOTOR in the Pick Devices window.
Open Proteus, click on the (Pick Device) button, and search for the following keywords: ARDUINO UNO (Requires Arduino Proteus library) 4 CHANNEL RELAY (Your newly installed library component) VSOURCE or ALTERNATOR (To represent 220V AC mains power) LAMP (To represent the loads/appliances) LOGICSTATE (Optional, for manual testing inputs) 2.

Creating a Proteus Library Component: Key Considerations
First, unzip the downloaded file. Inside, you should find two key folders: LIB and MODELS .
: Obtain the library zip file from trusted repositories like Electronics Tree The Engineering Projects Extract Files : Open the file and locate the Copy to Proteus Folder Library Files : Copy files with extensions to the Proteus folder (usually located at
To test the relay module, you can simulate an Arduino driving it. Schematic Setup: This comprehensive guide covers the importance of this
Paste them directly into the folder located in step 2.
Wire the input pins () to digital output pins on the Arduino (e.g., Pins 2, 3, 4, and 5) or link them to individual Logic State toggles for quick testing. Step 3: Wiring the Load Side For each of the four relay channels:
A standard 4-channel relay module typically supports the following:
A 4-channel relay module contains four independent electronic switches. Each switch can control high-voltage, high-current AC or DC loads using low-voltage logic signals from microcontrollers like Arduino, PIC, or STM32. Key Features and Specifications If Proteus displays a "Simulation is not running
📌 This is a simulation model – for real hardware, use an external 5V supply if the load is high.
A quick web search for "4 channel relay module library for Proteus download" will bring up a variety of these results, including direct links from posts that provide the necessary files.

Enhances security by separating the control circuit (low voltage) from the load circuit (high voltage).
Check that your microcontroller pins are explicitly set as outputs in your source code.
