--- 4 Channel Relay Module Library For Proteus 2021 【2026】

Usually, he saw the primitive 'RELAY-SPST' symbols. But today, the list had shifted. At the top, highlighted in bold, was a new component: .

If you are looking to simulate a circuit that controls multiple AC appliances, motors, or lights, you need this specific component. Below is a guide on how to get it, install it, and use it effectively.

void setup() pinMode(2, OUTPUT); pinMode(3, OUTPUT); pinMode(4, OUTPUT); pinMode(5, OUTPUT);

: Supports simulation of high-power AC (up to 250V) or DC (up to 30V) loads through its contacts, even though the control side operates on 5V. Component Pinout Power supply for the module (typically 5V in simulation). Common ground connection. Control signal inputs for each respective relay channel. NO / NC / COM

Here’s a helpful write-up you can use for documentation, a blog post, or a project report.

On the screen, the simulation bar turned red. Timestep too small. Another crash.
