現(xiàn)場控制或檢測元件輸入給PLC各種控制信號，如限位開關(guān)、操作按鈕、選擇開關(guān)以及其他一些傳感器輸出的開關(guān)量或模擬量等，通過輸入接口電路將這些信號轉(zhuǎn)換成CPU能夠接收和處理的信號。輸出接口電路將CPU送出的弱電控制信號轉(zhuǎn)換成現(xiàn)場需要的強電信號輸出，以驅(qū)動電磁閥、接觸器等被控設(shè)備的執(zhí)行元件。輸入接口用于接收和采集兩種類型的輸入信號，一類是由按鈕、轉(zhuǎn)換開關(guān)、行程開關(guān)、繼電器觸頭等開關(guān)量輸入信號；另一類是由電位器、測速發(fā)電機和各種變換器提供的連續(xù)變化的模擬量輸入信號。直流輸入接口電路為例，R1是限流與分壓電阻，R2與C構(gòu)成濾波電路，濾波后的輸入信號經(jīng)光耦合器T與內(nèi)部電路耦合。當(dāng)輸入端的按鈕SB接通時，光耦合器T導(dǎo)通，直流輸入信號被轉(zhuǎn)換成PLC能處理的5V標(biāo)準(zhǔn)信號電平(簡稱TTL)，同時LED輸入指示燈亮，表示信號接通。微電腦輸入接口電路一般由寄存器、選通電路和中斷請求邏輯電路組成，這些電路集成在一個芯片上。交流輸入與交直流輸入接口電路與直流輸入接口電路類似。

可編程控制器（PLC）具有結(jié)構(gòu)靈巧，硬件配置靈活方便、可靠性高、抗干擾能力強，易學(xué)易用的特點，已作為普遍的自動化控制器件廣泛應(yīng)用于各行各業(yè)?！禤LC原理及應(yīng)用》課程已成為工科院校一門覆蓋面較廣的專業(yè)課，作為學(xué)校如何培養(yǎng)出高素質(zhì)應(yīng)用型PLC人才，這成為社會、學(xué)校、教師與家長關(guān)注的焦點。根據(jù)多年的教學(xué)實踐，就影響PLC人才培養(yǎng)的各個因素的提高與協(xié)同
