is the game-changer your workspace needs. This library provides a pre-configured, "all-in-one" module that mimics the popular physical 4-channel relay boards used with Arduino and Raspberry Pi Why Use the 4-Channel Module Library? 4 channel relay module library for proteus new

The 4-channel relay module is a ubiquitous component in embedded systems, enabling low-voltage microcontrollers (3.3V/5V) to control high-voltage appliances (110V/250V AC). However, Proteus’s default library does not include a packaged 4-channel variant with opto-isolators, transistors, LEDs, and screw terminals. Engineers often resort to using four individual relays, which clutters schematics and fails to simulate the driver circuitry (e.g., ULN2803 or individual transistors). To add a new 4-channel relay module to

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. The 4-channel relay module is a ubiquitous component
