The simulation model typically provides three pins for each relay: (Normally Open), and (Normally Closed). Safety Isolation:

For years, Proteus users struggled to find an accurate, ready-to-use . Most default installations only offered raw relays (e.g., RELAY or RLY2 ), missing the optocouplers, transistors, and LED indicators present on real-world modules. Today, we introduce the new 4 channel relay module library for Proteus —a game-changer for simulating IoT and automation projects.

目前，最活跃、更新最及时的Proteus第三方库来源是ELECTRONICS TREE网站。该网站于2025年10月发布了，其中就包含了4路继电器模块所需的元件模型。用户可以直接在ELECTRONICS TREE网站找到下载链接，相关页面还附带了详细的安装说明和使用演示。

In this article, we will explore what this new library offers, how to download and install it, and step-by-step instructions to simulate a 4-channel relay with an Arduino. 4 channel relay module library for proteus new

The story of the 4-channel relay module library for Proteus is one of evolution in virtual prototyping. For years, engineers and students simulating home automation projects in Proteus VSM

Follow these steps to integrate the new library into your Proteus environment:

| Parameter | Value | | :--- | :--- | | Coil Voltage | 5V DC | | Max Switching Voltage | 250V AC / 30V DC | | Max Switching Current | 10A per channel | | Input Control Signal | TTL Level (0-5V) | | Isolation | Optocoupler (PC817) | | Status LEDs | 4 (One per channel) | | Power LED | 1 (Red) | Today, we introduce the new 4 channel relay

void loop() for (int i = 0; i < 4; i++) digitalWrite(relayPins[i], LOW); // Activate relay delay(1000); digitalWrite(relayPins[i], HIGH); // Deactivate relay delay(1000);

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

To illustrate, consider a project from duino4projects. An ATmega328P-based Arduino controls four 12V relays via a ULN2003 driver IC using simple two-digit serial commands (e.g., "21" to turn Relay #2 ON). This demonstrates serial control, firmware, driver electronics, and simulation, covering everything from basic code to industry-standard workflows.

To simulate switching behavior:

The official Proteus library doesn't include a ready-to-use 4-channel relay component, so you'll need to rely on third-party sources. These are the most reliable and up-to-date sources:

Upload a simple sequential sequence to your Arduino model to verify that all four channels switch independently:
