3．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)。
