．輸入/輸出接口
（1）輸入接口：
光電耦合器由兩個(gè)發(fā)光二極度管和光電三極管組成。
發(fā)光二級(jí)管：在光電耦合器的輸入端加上變化的電信號(hào)，發(fā)光二極管就產(chǎn)生與輸入信號(hào)變化規(guī)律相同的光信號(hào)。
光電三級(jí)管：在光信號(hào)的照射下導(dǎo)通，導(dǎo)通程度與光信號(hào)的強(qiáng)弱有關(guān)。在光電耦合器的線性工作區(qū)內(nèi)，輸出信號(hào)與輸入信號(hào)有線性關(guān)系。
輸入接口電路工作過(guò)程：當(dāng)開(kāi)關(guān)合上，二極管發(fā)光，然后三極管在光的照射下導(dǎo)通，向內(nèi)部電路輸入信號(hào)。當(dāng)開(kāi)關(guān)斷開(kāi)，二極管不發(fā)光，三極管不導(dǎo)通。向內(nèi)部電路輸入信號(hào)。也就是通過(guò)輸入接口電路把外部的開(kāi)關(guān)信號(hào)轉(zhuǎn)化成PLC內(nèi)部所能接受的數(shù)字信號(hào)。
（2）輸出接口
PLC的繼電器輸出接口電路
工作過(guò)程：當(dāng)內(nèi)部電路輸出數(shù)字信號(hào)1，有電流流過(guò)，繼電器線圈有電流，然后常開(kāi)觸點(diǎn)閉合，提供負(fù)載導(dǎo)通的電流和電壓。當(dāng)內(nèi)部電路輸出數(shù)字信號(hào)0，則沒(méi)有電流流過(guò)，繼電器線圈沒(méi)有電流，然后常開(kāi)觸點(diǎn)斷開(kāi)，斷開(kāi)負(fù)載的電流或電壓。也就是通過(guò)輸出接口電路把內(nèi)部的數(shù)字電路化成一種信號(hào)使負(fù)載動(dòng)作或不動(dòng)作。
三種類型：
繼電器輸出：有觸點(diǎn)、壽命短、頻率低、交直流負(fù)載
晶體管輸出：無(wú)觸點(diǎn)、壽命長(zhǎng)、直流負(fù)載
晶閘管輸出：無(wú)觸點(diǎn)、壽命長(zhǎng)、交流負(fù)載
