Follow these instructions carefully. The process differs slightly based on your Windows version.

: Each relay can switch a separate circuit (AC or DC) independently using a control signal. Operating Voltage : Modules are typically available in 5V, 12V, or 24V versions to match your control logic. Trigger Modes : Often features a jumper to select between high-level trigger modes.

(Even though it's simulation, you need to compile a HEX file or use the Arduino source code in Proteus)

the files and locate your Proteus library folder. For Proteus 8 , this is typically: C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\DATA\LIBRARY .
