輸入接口用于接收和采集兩種類型的輸入信號(hào),一類是由按鈕、轉(zhuǎn)換開(kāi)關(guān)、行程開(kāi)關(guān)、繼電器觸頭等開(kāi)關(guān)量輸入信號(hào);另一類是由電位器、測(cè)速發(fā)電機(jī)和各種變換器提供的連續(xù)變化的模擬量輸入信號(hào)。
以圖2所示的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(hào)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(shí),光耦合器T導(dǎo)通,直流輸入信號(hào)被轉(zhuǎn)換成PLC能處理的5V標(biāo)準(zhǔn)信號(hào)電平(簡(jiǎn)稱TTL),同時(shí)LED輸入指示燈亮,表示信號(hào)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(qǐng)求邏輯電路組成,這些電路集成在一個(gè)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。
