To add this module to your Proteus software, follow these steps:
If you need help for the library files or want to expand this simulation into an IoT-based control circuit , let me know! Share public link
For 90% of users, Library A (The Engineering Projects) is the most stable and visually informative. For high-voltage isolation studies, choose Library B .
Connect the remaining terminal of the AC Lamp back to the of the AC Alternator. Repeat this sequence for all four channels. Writing the Arduino Control Code
5. Simulating the Relay Module with a Microcontroller (e.g., Arduino)
A simply packages four independent relays on a single board. This allows a single microcontroller like an Arduino Uno or an ESP32 to manage four separate high-power devices simultaneously.
A standard 4-channel relay module typically supports the following:
