輸入/輸出（I/O）接口 I/O接口是PLC與輸入/輸出設(shè)備連接的部件。輸入接口接受輸入設(shè)備（如按鈕、傳感器、觸點(diǎn)、行程開關(guān)等）的控制信號(hào)。輸出接口是將主機(jī)經(jīng)處理后的結(jié)果通過功放電路去驅(qū)動(dòng)輸出設(shè)備（如接觸器、電磁閥、指示燈等）。I/O接口一般采用光電耦合電路，以減少電磁干擾，從而提高了可靠性。I/O點(diǎn)數(shù)即輸入/輸出端子數(shù)是PLC的一項(xiàng)主要技術(shù)指標(biāo)，通常小型機(jī)有幾十個(gè)點(diǎn)，中型機(jī)有幾百個(gè)點(diǎn)，大型機(jī)將超過千點(diǎn)。
