--- 4: Channel Relay Module Library For Proteus !!link!!

It provides a realistic 3D and 2D footprint matching popular commercial modules (like Songle relays).

With the wiring completed, you can run the simulation using two different approaches: Method A: Manual Testing (LogicState)

EEWorld and other simulation forums sometimes share models.

: Typically operates on 5V DC (range: 3.75V to 6V).

Using the pre-built module in simulation saves you the time of wiring these individual components every time you start a new project. --- 4 Channel Relay Module Library For Proteus

Once installed, you can build a complete interactive simulation. Follow these steps to set up a basic testing environment using an Arduino UNO. 1. Component Selection

4-Channel Relay Module library for Proteus a third-party add-on that allows you to simulate high-voltage switching circuits using microcontrollers like Arduino, PIC, or ESP32 within the Proteus VSM environment

| Pin Name | Proteus Net Label | Description | |----------|-------------------|-------------| | VCC | +5V | Power for optocoupler/transistor side | | GND | GND | Ground | | IN1 | GPIO_PIN1 | Active High control from MCU | | IN2 | GPIO_PIN2 | Active High control from MCU | | IN3 | GPIO_PIN3 | Active High control from MCU | | IN4 | GPIO_PIN4 | Active High control from MCU | | JD-VCC | +5V_Relay | Optional isolated supply (jumper to VCC in sim) | | COM1 | Load_Return | Common (connect to AC/DC source) | | NO1 | Load_Hot | Normally Open (connect to device) | | NC1 | - | Normally Closed (leave open unless needed) |

Paste them directly into the folder identified in Step 2. It provides a realistic 3D and 2D footprint

He compiled the .hex file and loaded it into the microcontroller properties in Proteus.

PCB Footprint and 3D Model

Once installed, you can build a complete automation circuit. This example demonstrates how to control four separate AC appliances using an Arduino Uno and the 4-channel relay library. 1. Gather Components from the Device Library

When Proteus rebooted, Omar opened the component picker (the 'P' button). He typed "RELAY" into the search bar. Using the pre-built module in simulation saves you

Once installed, you can build a complete automation circuit. 1. Component Selection

Each channel includes Common (COM) , Normally Open (NO) , and Normally Closed (NC) terminals.
