In the bustling tech hub of Neo-Delhi, Elias was a tinkerer with a deadline. He was building "The Automator," a smart home system that could control everything from coffee machines to heavy-duty fans. The heart of his project was a 4-channel relay module , but there was a snag: his simulation software, , didn’t have the specific part in its standard library.

Without a way to simulate the switching logic, Elias was stuck. He couldn’t risk frying his hardware without testing his code first. Late one night, he found an old forum thread titled

"4 Channel Relay Module Library for Proteus NEW - Updated V2." He downloaded the

files, carefully dropping them into his Proteus library folder. When he reopened the software and typed "Relay" into the component picker, there it was—a perfectly rendered 4-channel module, complete with the optocoupler pins and LED indicators.

With the new library, Elias wired his virtual Arduino to the four pins. He hit "Play." On his screen, the virtual relays clicked in a satisfying sequence, the green lights flickering just as they would in real life.

The simulation worked perfectly. Two days later, Elias built the physical version, and because he’d solved the puzzle in Proteus first, "The Automator" sprang to life on the very first try. step-by-step instructions on how to install a new library into your Proteus folders?

A new 4-channel relay module library for Proteus (often provided by developers like Electronics Tree or The Engineering Projects) allows engineers and hobbyists to simulate complex switching tasks without needing the physical hardware.

This module typically integrates four independent relays, often 5V DC operated, which can control high-voltage AC (up to 250V) or DC loads. Key Features of the New Library

Independent Control: Each of the four channels can be toggled individually via digital pins (IN1, IN2, IN3, IN4).

Visual Indicators: High-quality libraries include status LEDs for each relay that light up during simulation when a channel is active.

Optical Isolation Simulation: Many 4-channel modules use optocouplers to isolate the low-voltage control circuit from the high-voltage load; advanced Proteus models reflect this behavioral isolation.

Standardized Pinouts: The module includes VCC, GND, and the four input pins, making it easy to interface with Arduino, PIC, or Raspberry Pi in the workspace. How to Install the 4-Channel Relay Library

How to Add Arduino UNO Library to Proteus | Step-by-Step Guide

The 4 Channel Relay Module library for Proteus allows you to simulate high-voltage switching using low-voltage control signals from microcontrollers like Arduino or Raspberry Pi. This virtual module is essential for testing home automation or industrial control projects before physical assembly. How to Add the Library to Proteus

To use a new 4-channel relay module in your simulations, follow these steps to integrate the library files:

Exploring Relay Modules: Definition, Functions and Principles

Since Proteus (versions 8.6 through 8.16) does not always include a pre-made, integrated "4-Channel Relay Module" component in the default library (it usually only provides single relays), most users rely on a schematic design or a custom library file to simulate it.

Below is the solution for getting this module into your Proteus workspace.

8. Advantages of Custom Library

1. Accurate Logic Modeling

Arduino Sketch (Firmware):

Upload this code to your virtual Arduino in Proteus.

// Control 4 Channel Relay Module - Simulation Example
// Pins for the 4 relays
const int relayPins[4] = 8, 9, 10, 11;

void setup() 
// Initialize all relay pins as outputs
for (int i = 0; i < 4; i++) 
pinMode(relayPins[i], OUTPUT);
// Start with all relays OFF (For ACTIVE LOW module: HIGH = OFF)
digitalWrite(relayPins[i], HIGH);



void loop() 
// Sequence 1: Turn on Relay 1, wait, then Relay 2, etc.
for (int i = 0; i < 4; i++) 
digitalWrite(relayPins[i], LOW);  // Activate Relay (Active LOW)
delay(500);                       // Keep ON for 500ms
digitalWrite(relayPins[i], HIGH); // Deactivate Relay



// Sequence 2: All relays ON together
for (int i = 0; i < 4; i++) 
digitalWrite(relayPins[i], LOW);
delay(2000); // All ON for 2 seconds


// Sequence 3: All relays OFF
for (int i = 0; i < 4; i++) 
digitalWrite(relayPins[i], HIGH);
delay(1000);

4. Simulation Example: Arduino Controlled 4-Channel Relay

How to Use in Proteus (Step-by-step)

  1. Install the library file (.IDX/.LIB/.HEX as appropriate) into Proteus Components folder and restart Proteus.
  2. Place the 4-channel relay module component on the schematic. Choose the variant (5V/12V, opto-isolated or not).
  3. Wire VCC/JD-VCC and GND. If using separate JD-VCC, supply coil voltage to JD-VCC and MCU supply to VCC as required by your hardware.
  4. Connect IN1–IN4 to microcontroller GPIO pins (or test switches) and ensure correct active polarity (invert signals if using active-low model).
  5. Connect COM/NO/NC pins to your load and source. For AC mains load simulations, use proper AC source components and observe safety limitations — Proteus simulates behavior but is not a substitute for safe hardware practice.
  6. Run digital simulation. Observe LEDs and relay contact states. Use oscilloscope/logic analyzer probes to inspect coil drive and contact switching transients.

4. Simulation Model (SPICE / Virtual)

To simulate switching behavior:

* Subcircuit for 4-Channel Relay Module
.SUBCKT RELAY_4CH_MODULE IN1 IN2 IN3 IN4 VCC GND COM1 NC1 NO1 COM2 NC2 NO2 COM3 NC3 NO3 COM4 NC4 NO4
  * Channel 1
  R1 IN1 VCC 1K
  D1 COM1 GND 1N4148
  RLY1 COM1 NC1 NO1 RELAY_VIRTUAL
  * Repeat for channels 2-4
.ENDS

But easier: Use Proteus’s built-in RELAY model with a DEFAULT coil resistance of 100Ω and add OPTOCOUPLER for isolation visualization.

3.2 Schematic Symbol Design

Create a rectangular symbol with the following pins:

| Pin Number | Pin Name | Type | Description | |------------|----------|------|-------------| | 1 | VCC | Power | Module supply (5V/12V) | | 2 | GND | Power | Ground | | 3 | JD-VCC | Power | Relay supply (isolated) | | 4 | IN1 | Input | Channel 1 control | | 5 | IN2 | Input | Channel 2 control | | 6 | IN3 | Input | Channel 3 control | | 7 | IN4 | Input | Channel 4 control | | 8 | COM1 | Passive | Common terminal Relay 1 | | 9 | NC1 | Passive | Normally Closed Relay 1 | | 10 | NO1 | Passive | Normally Open Relay 1 | | 11 | COM2 | Passive | Common terminal Relay 2 | | 12 | NC2 | Passive | Normally Closed Relay 2 | | 13 | NO2 | Passive | Normally Open Relay 2 | | 14 | COM3 | Passive | ... (repeat for 3 & 4) | | ... | ... | ... | ... |

Note: In practice, many users create a hierarchical block instead of exposing all 14 pins to keep schematics clean.
