輸入/輸出滯后時間又稱系統響應時間，是指PLC部輸入信號發(fā)生變化的時刻至它控制的有關外部輸出信號發(fā)生變化的時刻之間的時間間隔，它由輸入電路濾波時間、輸出電路的滯后時間和因掃描工作方式產生的滯后時間這三部分組成。

輸入模塊的RC濾波電路用來濾除由輸入端引入的干擾噪聲，因外接輸入觸點動作時產生的抖動引起的不良影響，濾波電路的時間常數決定了輸入濾波時間的長短，其典型值為10ms左右。

輸出模塊的滯后時間與模塊的類型有關，繼電器型輸出電路的滯后時間一般在10ms左右;雙向晶閘管型輸出電路在負載通電時的滯后時間約為1ms，負載由通電到斷電時的滯后時間為10ms;晶體管型輸出電路的滯后時間一般在1ms以下。

PLC總的響應延遲時間一般只有幾十ms，對于一般的系統是無關緊要的。要求輸入輸出信號之間的滯后時間盡量短的系統，可以選用掃描速度快的PLC或采取其他措施。
