開關量
開關量主要指開入量和開出量,是指一個裝置所帶的輔助點,譬如變壓器的溫控器所帶的繼電器的輔助點(變壓器超溫后變位)、閥門凸輪開關所帶的輔助點(閥門開關后變位),接觸器所帶的輔助點(接觸器動作后變位)、熱繼電器(熱繼電器動作后變位),這些點一般都傳給PLC或綜保裝置,電源一般是由PLC或綜保裝置提供的,自己本身不帶電源,所以叫無源接點,也叫PLC或綜保裝置的開入量。
1、數(shù)字量
在時間上和數(shù)量上都是離散的物理量稱為數(shù)字量。把表示數(shù)字量的信號叫數(shù)字信號。把工作在數(shù)字信號下的電子電路叫數(shù)字電路。
例如:
用電子電路記錄從自動生產(chǎn)線上輸出的零件數(shù)目時,每送出一個零件便給電子電路一個信號,使之記1,而平時沒有零件送出時加給電子電路的信號是0,所在為記數(shù)??梢?,零件數(shù)目這個信號無論在時間上還是在數(shù)量上都是不連續(xù)的,因此他是一個數(shù)字信號。小的數(shù)量單位就是1個。
