6SE6440-2UD25-5CA1按電源配置類型

(1) 直流輸入電路如圖1，直流輸入電路要求外部輸入信號的元件為無源的干接點(diǎn)或直流有源的無觸點(diǎn)開關(guān)接點(diǎn)，當(dāng)外部輸入元件與電源正極導(dǎo)通，電流通過R1，光電耦合器內(nèi)部LED，VD1(接口指示)到COM端形成回路，光電耦合器內(nèi)部接收管接受外部元件導(dǎo)通的信號，傳輸?shù)絻?nèi)部處理;這種由直流電提供電源的接口方式，叫直流輸入電路;

直流電可以由PLC內(nèi)部提供也可以外接直流電源提供給外部輸入信號的元件。R2在電路中的作用是旁路光電耦合器內(nèi)部LED的電流，保證光電耦合器LED不被兩線制接近開關(guān)的靜態(tài)泄漏電流導(dǎo)通。
