在PLC內(nèi)部存儲(chǔ)器中有專用于輸入狀態(tài)存儲(chǔ)的輸入繼電器區(qū)，各輸入設(shè)備（開關(guān)、按鈕、行程開關(guān)或傳感器信號(hào)）的狀態(tài)經(jīng)由輸入接口電路存儲(chǔ)在該區(qū)域內(nèi)，每個(gè)輸入繼電器可存儲(chǔ)一個(gè)輸入設(shè)備狀態(tài)。PLC中使用的"繼電器"并非實(shí)體繼電器，而是"軟繼電器"，可提供無數(shù)個(gè)常開、常閉觸點(diǎn)用于編程。每個(gè)"軟繼電器"僅對(duì)應(yīng)PLC存儲(chǔ)單元中的一位（bit），該位狀態(tài)為"1"，表示該"軟繼電器線圈"通電，則程序中所有該繼電器的觸點(diǎn)都動(dòng)作。輸入繼電器作為PLC接收外部主令信號(hào)的器件，通過接線與外部輸入設(shè)備相聯(lián)系，其"線圈"狀態(tài)只能由外部輸入信號(hào)驅(qū)動(dòng)。
