4 Channel Relay Module Library For Proteus New Jun 2026
In the Arduino IDE, go to and check the box for Show verbose output during: compilation . Click Verify/Compile .
While Proteus has a library of generic relays, it lacks a dedicated "module" that includes the required peripheral components—such as diodes, optocouplers, and transistors—that make it work immediately in a simulation.
True module libraries provide standard VCC, GND, and input pins (IN1, IN2, IN3, IN4) that match physical board layouts.

Recheck that you copied the files into the correct LIBRARY folder and restarted Proteus.
Pins are clearly labeled for VCC, GND, and IN1-IN4, reducing wiring errors.
On the output side of each relay, you can hook up simulated AC or DC loads. For a visual confirmation during simulation, wire an and an alternating current source (ALTERNATER) across the Normally Open (NO) and Common (COM) terminals of the relay channels. Sample Arduino Testing Code In the Arduino IDE, go to and check
Verify that you have attached an active power source terminal to VCC. A digital logic pin alone cannot drive the simulation module without a defined VCC power rail.
void setup() // Initialize pins as outputs pinMode(RELAY1, OUTPUT); pinMode(RELAY2, OUTPUT); pinMode(RELAY3, OUTPUT); pinMode(RELAY4, OUTPUT);
Connect the remaining terminal of all four lamps back to the second side of the AC ALTERNATOR to complete the loop. Arduino Sample Code for Testing True module libraries provide standard VCC, GND, and
Change digitalWrite(pin, HIGH) to LOW to activate the relay, and vice versa.
