Here’s what she did (and what you can learn from her steps):
She saved it as 4CH_RELAY_MODULE.LIB and placed it in the Proteus LIBRARY folder. Then, in Proteus, she used Tools > New Component to combine the schematic, footprint, and properties (e.g., "Operating Voltage: 5V", "Logic: Active LOW"). --- 4 Channel Relay Module Library For Proteus
Maya realized she didn't need just any relay—she needed her relay. She decided to build a custom 4-Channel Relay Module Library for Proteus using the Proteus ARES and ISIS tools. Here’s what she did (and what you can
Maya passed her preliminary review. More importantly, she shared her 4CH_RELAY_MODULE.LIB file on her university’s forum. Within a week, 15 other students had used it for their projects—saving them from blown fuses, magic smoke, and late-night panic. She decided to build a custom 4-Channel Relay
The Overheated Lab
She didn't need a perfect footprint for simulation, but she added a 16-pin DIP header footprint so that later, if she designed a PCB, the layout would match a real module's pinout.
