Proteus Design Suite (specifically ISIS) is a leading EDA software for schematic capture and simulation. While it has an extensive component library, pre-assembled modules (like the 4-channel relay board) are often missing or represented as generic switches.
The 4-channel relay module library for Proteus offers several advantages, including: --- 4 Channel Relay Module Library For Proteus
A library includes these SPICE models internally: Proteus Design Suite (specifically ISIS) is a leading
