如果验证成功，恭喜你——4路继电器模块库已经就绪。
Connect the components according to this standard automation schematic:
Which are you planning to simulate (Arduino, PIC, 8051)?
Several reputable hobbyist sites provide updated Proteus libraries for these modules: 4 channel relay module library for proteus new

Place an ALTERNATOR component to mimic a 220V AC wall outlet.

To develop a complete, reusable Proteus library component named RELAY_4CH that accurately models:
Place a LAMP component to act as your high-voltage appliance. Wire the Loop:
void loop() // Sequence 1: Turn on Relay 1, wait, then Relay 2, etc. for (int i = 0; i < 4; i++) digitalWrite(relayPins[i], LOW); // Activate Relay (Active LOW) delay(500); // Keep ON for 500ms digitalWrite(relayPins[i], HIGH); // Deactivate Relay This is often more reliable than third-party libraries
If you cannot find a specific "Module" part, the standard engineering practice in Proteus is to build the sub-circuit. This is often more reliable than third-party libraries.
, feature better visual animations and improved logic for "low-level effective" triggering, which is common in real relay modules. How the Modern Simulation Works In a typical Proteus project using this new library:
Your code assumes Active-High logic, but the library module simulates an Active-Low physical board.
如果每次仿真都手工搭建这四路电路，不仅耗时、易出错，而且原理图会变得繁杂臃肿。而使用专门设计的4路继电器模块库，只需一次拖放，即可在Proteus原理图中获得一个“开箱即用”的完整模块，其背后已经内置了正确的电气模型、引脚定义和仿真行为，极大提升了设计效率。
