德國圖爾克（TURCK）、德國賀德克（HYDAC）、皮爾磁(PLIZ)、美商實(shí)塊等歐美進(jìn)口品牌時(shí)間繼電器的電氣控制系統(tǒng)中是一個(gè)非常重要的元器件。一般分為通電延時(shí)和斷電延時(shí)兩種類型。    從動(dòng)作的原理上有電子式、機(jī)械式等。電子式的是采用電容充放電再配合電子元件的原理來實(shí)現(xiàn)延時(shí)動(dòng)作。機(jī)械式的樣式較多，有利用氣囊、彈簧的氣囊式；鐘表擒縱裝置的；也有使用小型罩極同步電機(jī)帶動(dòng)凸輪的，現(xiàn)在會(huì)有更多的新式的時(shí)間繼電器出現(xiàn)。    時(shí)間繼電器的用途就是配合工藝要求，執(zhí)行延時(shí)指令。繼電器    當(dāng)輸入的物理量達(dá)到規(guī)定值時(shí)，其電氣輸出電路被接通或阻斷的一種自動(dòng)電器。廣泛用于生產(chǎn)過程自動(dòng)化裝置，電力系統(tǒng)保護(hù)裝置，各類遠(yuǎn)動(dòng)、遙控和通信裝置，是現(xiàn)代自動(dòng)控制系統(tǒng)中最基礎(chǔ)的電器元件之一。  繼電器是一種當(dāng)輸入量（電、磁、聲、光、熱）達(dá)到一定值時(shí)，輸出量將發(fā)生跳躍式變化的自動(dòng)控制器件。 繼電器的輸入信號(hào)x從零連續(xù)增加達(dá)到銜鐵開始吸合時(shí)的動(dòng)作值xx，繼電器的輸出信號(hào)立刻從y=0跳躍到y(tǒng)=ym，即常開觸點(diǎn)從斷到通。一旦觸點(diǎn)閉合，輸入量x繼續(xù)增大，輸出信號(hào)y將不再起變化。當(dāng)輸入量x從某一大于xx值下降到xf，繼電器開始釋放，常開觸點(diǎn)斷開（如圖1）。我們把繼電器的這種特性叫做繼電特性，也叫繼電器的輸入-輸出特性。  釋放值xf與動(dòng)作值xx的比值叫做反饋系數(shù)，即  Kf=xf/xx  觸點(diǎn)上輸出的控制功率Pc與線圈吸收的最小功率P0之比叫做繼電器的控制系數(shù)，即Kc=PC/P0繼電器的分類。西門子3RB系列：3RB2016-2ND0
