是具有隔離功(gong)能的自動(dong)開關元件，廣泛應(ying)用于遙控、遙測(ce)、通訊、自動(dong)控制、機電一體化及電力電子(zi)設(she)備中，是最重要的控制元件之一。 德國(guo)PILZ繼(ji)電器(qi)(qi)一(yi)(yi)般(ban)都(dou)有(you)能反映一(yi)(yi)定(ding)輸入(ru)(ru)變量（如電流(liu)、電壓、功率(lv)、阻抗、頻(pin)率(lv)、溫度、壓力、速度、光等）的(de)感應機構(gou)（輸入(ru)(ru)部分）；有(you)能對(dui)(dui)被控(kong)電路實(shi)現“通"、“斷(duan)"控(kong)制的(de)執行機構(gou)（輸出部分）；在繼(ji)電器(qi)(qi)的(de)輸入(ru)(ru)部分和輸出部分之間，還有(you)對(dui)(dui)輸入(ru)(ru)量進行耦合隔離，功能處理和對(dui)(dui)輸出部分進行驅動的(de)中間機構(gou)（驅動部分）。 的作用(yong)：作為控制(zhi)元件，概括起來，繼電(dian)器有如下幾種作用(yong)： 1） 擴(kuo)大控制(zhi)范圍：例如，多觸點繼電器控制(zhi)信(xin)號達到某一定值時，可以按觸點組的(de)不同形式，同時換接、開斷、接通多路電路。 2） 放大(da)：例如，靈敏型(xing)繼電(dian)器(qi)、中間繼電(dian)器(qi)等，用一個很微小的控制量，可以(yi)控制很大(da)功率的電(dian)路。 3）綜合信號：例如，當多(duo)個控制信號按(an)規(gui)定的形(xing)式輸入多(duo)繞組繼(ji)電(dian)器時，經過比較綜合，達到預定的控制效(xiao)果。 4） 自(zi)動、遙控、監測：例(li)如(ru)，自(zi)動裝置上的繼(ji)電器與其他(ta)電器一起(qi)，可(ke)以組成程(cheng)序控制線(xian)路，從(cong)而實現(xian)自(zi)動化(hua)運行。
