In the keywords search box, type 4 Channel Relay or the specific keyword provided by your downloaded library documentation. Double-click the module to add it to your devices list. Wiring Diagram and Interfacing
int relayPins[] = 2, 3, 4, 5; // Arduino pins connected to IN1 to IN4
Installing the libraries needed for your 4-channel relay module or for the Arduino model follows a standard process. 4 channel relay module library for proteus new
. This new library provides a single component with four input pins (IN1-IN4) and power pins (VCC, GND), drastically reducing circuit clutter. The 2025 Updates : Recent versions of the library, showcased in New Arduino Relay Modules (2025)
The following system requirements are recommended for using the 4-channel relay module library:
Place an ALTERNATOR component to mimic a 220V AC wall outlet.
Using a dedicated 4-Channel Relay Module library offers several advantages: In your simulated circuit, replace the logic toggles

Proteus is a popular software tool used for designing and simulating electronic circuits. It is widely used by engineers, students, and hobbyists to design, test, and validate their circuit designs before building a physical prototype. One of the key features of Proteus is its ability to simulate a wide range of electronic components, including relay modules. In this article, we will discuss the 4-channel relay module library for Proteus and provide a step-by-step guide on how to use it.
