Below is the solution for getting this module into your Proteus workspace.
Connect one terminal of the to the COM terminal of Relay Channel 1.
: Known for producing updated Arduino-compatible module libraries. You can often find the latest Arduino Relay Modules for Proteus on their site.
: To simplify this, developers created custom library files ( ) specifically for the 4-channel relay board 4 channel relay module library for proteus new
Connect the following in Proteus:
If the relays do not turn off, verify your code logic matches the trigger type of the module library. Low-trigger modules require a logic HIGH output from the microcontroller to turn off.
While older Proteus libraries contained generic relay components (e.g., RELAY or RLY-SPST ), they lacked the integrated structure of a . A standard 4-channel relay module (commonly based on the SRD-05VDC-SL-C or JQC-3FF relays) includes: Below is the solution for getting this module
Connect digital output pins from your virtual microcontroller (like an Arduino Uno) to the IN1 , IN2 , IN3 , and IN4 pins of the relay block.
: The simulation block mirrors the exact physical pins (VCC, GND, IN1, IN2, IN3, IN4) of real-world modules.

If you prefer control, create a subcircuit in Proteus using discrete relays, optocouplers, and transistors, then save as a custom module. However, the new library eliminates this repetitive work.

Using a dedicated 4-Channel Relay Module library offers several advantages:
High-quality models often include interactive LEDs that glow when a specific relay is energized. Realistic Terminals:
: Instead of a messy web of four separate relays, you get a single, professional-looking component that saves schematic space. Realistic Simulation
