3．輸入輸出單元（I/O單元）

I/O單元實(shí)際上是PLC與被控對(duì)象間傳遞輸入輸出信號(hào)的接口部件。I/O單元有良好的電隔離和濾波作用。接到PLC輸入接口的輸入器件是各種開(kāi)關(guān)、按鈕、傳感器等。PLC的各輸出控制器件往往是電磁閥、接觸器、繼電器，而繼電器有交流和直流型，高電壓型和低電壓型，電壓型和電流型。

4．電源

PLC電源單元包括系統(tǒng)的電源及備用電池，電源單元的作用是把外部電源轉(zhuǎn)換成內(nèi)部工作電壓。PLC內(nèi)有一個(gè)穩(wěn)壓電源用于對(duì)PLC的CPU單元和I/O單元供電。

5．編程器

編程器是PLC的最重要外圍設(shè)備。利用編程器將用戶程序送入PLC的存儲(chǔ)器，還可以用編程器檢查程序，修改程序，監(jiān)視PLC的工作狀態(tài)。除此以外，在個(gè)人計(jì)算機(jī)上添加適當(dāng)?shù)挠布涌诤蛙浖?，即可用個(gè)人計(jì)算機(jī)對(duì)PLC編程。利用微機(jī)作為編程器，可以直接編制并顯示梯形圖。
