4 Channel Relay Module Library for Proteus

A allows you to simulate high-voltage switching circuits using microcontrollers like Arduino, PIC, or Raspberry Pi. Standard Proteus installations often lack pre-built modules, requiring the manual addition of external library files to visualize the module as a single unit rather than separate individual relays. 1.

Introduction

• Expose all functional pins: IN1–IN4 (control inputs), VCC (logic), JD-VCC or VCC_RELAY (relay coil supply), GND, and for each channel the contacts: NO (Normally Open), NC (Normally Closed), and COM (Common).
• Include optional pins for indicator LEDs (usually internal, not required externally) only if the simulation will model LED behavior.
• Clearly annotate active polarity (e.g., “INx — active LOW”).

Independent Control

: Features 4 individual channels that can be controlled separately via digital input pins (IN1–IN4). --- 4 Channel Relay Module Library For Proteus

Scenario:

Control 4 bulbs from an Arduino Uno.

• Rapid prototyping: A packaged module symbol accelerates schematic capture when multiple relays are required.
• Hardware/software co-simulation: In Proteus, modules can be driven by simulated microcontrollers (Arduino, PIC, AVR), enabling verification of control logic, timing, and interactions with loads.
• Documentation and teaching: A single labeled component is easier to explain in tutorials and classroom projects.
• Safety and isolation studies: Simulating relays helps illustrate contact behavior, flyback protection, and isolation between control and load circuits.
