4 Channel Relay Module Library For Proteus New Updated

继电器是一种通过电磁原理控制电路通断的电子开关，常用于单片机控制大功率设备。在Proteus自带的元件库中，虽然可以找到通用的 RELAY 符号，但它往往只是一个抽象的单通道模型，默认参数可能与实际模块不匹配，且仿真时需手动搭建驱动电路和线圈模型。

If the relay armature does not visibly move during operation, ensure you are using the active model component ( RELAY-SPDT ) rather than a passive, text-only library symbol. If you would like to expand this setup, tell me: Which microcontroller model you plan to use? 4 channel relay module library for proteus new

From the Proteus component library, place the following for one relay channel:

digitalWrite(RELAY1, HIGH); delay(1000);
