    Our Verdict: For 90% of users, Library A (The Engineering Projects) is the most stable and visually informative. For high-voltage isolation studies, choose Library B. Define Properties:

    Proteus supports VSM (Virtual System Modelling). You can embed a behavioral model:

    .MODEL RelayChannel (SWITCH)
+ RON=0.1
+ ROFF=1e6
+ VT=2.5   ; Threshold voltage for activation
+ VH=0.5   ; Hysteresis

    However, a simpler method: Use the built-in RELAY component already modeled with coil inductance and contact resistance. For the 4-channel module, replicate this four times inside a subcircuit.
