描述
可編程控制器利用I/O擴(kuò)展接口使I/O擴(kuò)展單元與PLC的基本單元實(shí)現(xiàn)連接,當(dāng)基本I/O單元的輸入或輸出點(diǎn)數(shù)不夠使用時(shí),可以用I/O擴(kuò)展單元來擴(kuò)充開關(guān)量I/O點(diǎn)數(shù)和增加模擬量的I/O端子。
3.外設(shè)接口
外設(shè)接口電路用于連接手持編程器或其他圖形編程器、文本顯示器,并能通過外設(shè)接口組成PLC的控制網(wǎng)絡(luò)。PLC通過PC/PPI電纜或使用MPI卡通過RS-485接口與計(jì)算機(jī)連接,可以實(shí)現(xiàn)編程、監(jiān)控、連網(wǎng)等功能。
4.電源
電源單元的作用是把外部電源(220V的交流電源)轉(zhuǎn)換成內(nèi)部工作電壓。外部連接的電源,通過PLC內(nèi)部配有的一個(gè)專用開關(guān)式穩(wěn)壓電源,將交流/直流供電電源轉(zhuǎn)化為PLC內(nèi)部電路需要的工作電源(直流5伏、正負(fù)12伏、24伏),并為外部輸入元件(如接近開關(guān))提供24V直流電源(僅供輸入端點(diǎn)使用),而驅(qū)動(dòng)PLC負(fù)載的電源由用戶提供。
