Once the component is added to your schematic, it will typically have the following pins: Connect to +5V or +3.3V. GND: Connect to ground.

Most 5V relay modules are Active-Low , meaning the relay activates when the input signal is 0V (GND) and deactivates at 5V (VCC). For each of the four relays on the

: Copy both the .LIB and .IDX files into this folder.

Even with a perfect library, simulations fail. Here are the top 3 errors:

Because Proteus focuses heavily on discrete components, simulating the popular breakout board (often featuring Songle relays and optocouplers) requires a consolidated custom model. The custom library simplifies your schematic layout by grouping the necessary pins, optocouplers, transistors, and diodes into a single, cohesive 4-channel visual block. Step-by-Step Installation of the Relay Library

: High-quality external libraries include the exact footprint dimensions. This ensures that if you transition your simulated schematic into a physical PCB design using Proteus ARES, the component will perfectly match the physical dimensions of the module you buy online. Step-by-Step Guide: Installing the Library

: Each relay can handle loads up to 10A at 250VAC or 30VDC .

Download the package, which typically contains two essential files: *.IDX (Index file for the Proteus search database) *.LIB (The graphical and functional library model) Step 2: Locate your Proteus Directory

The downloaded library might be a "black box." To truly understand and trust your simulation, you should know what is inside a good 4 Channel Relay Module library.
