一、繼電器的工作原理和特性   
     繼電器是一種電子控制器件，它具有控制系統(tǒng)（又稱(chēng)輸入回路）和被控制系統(tǒng)（又稱(chēng)輸出回路），通常應(yīng)用于自動(dòng)控制電路中，它實(shí)際上是用較小的電流去控制較大電流的一種“自動(dòng)開(kāi)關(guān)”。故在電路中起著自動(dòng)調(diào)節(jié)、安全保護(hù)、轉(zhuǎn)換電路等作用。
1、電磁繼電器的工作原理和特性
     電磁式繼電器一般由鐵芯、線圈、銜鐵、觸點(diǎn)簧片等組成的。只要在線圈兩端加上一定的電壓，線圈中就會(huì)流過(guò)一定的電流，從而產(chǎn)生電磁效應(yīng)，銜鐵就會(huì)在電磁力吸引的作用下克服返回彈簧的拉力吸向鐵芯，從而帶動(dòng)銜鐵的動(dòng)觸點(diǎn)與靜觸點(diǎn)（常開(kāi)觸點(diǎn)）吸合。當(dāng)線圈斷電后，電磁的吸力也隨之消失，銜鐵就會(huì)在彈簧的反作用力返回原來(lái)的位置，使動(dòng)觸點(diǎn)與原來(lái)的靜觸點(diǎn)（常閉觸點(diǎn)）吸合。這樣吸合、釋放，從而達(dá)到了在電路中的導(dǎo)通、切斷的目的。對(duì)于繼電器的“常開(kāi)、常閉”觸點(diǎn)，可以這樣來(lái)區(qū)分：繼電器線圈未通電時(shí)處于斷開(kāi)狀態(tài)的靜觸點(diǎn)，稱(chēng)為“常開(kāi)觸點(diǎn)”；處于接通狀態(tài)的靜觸點(diǎn)稱(chēng)為“常閉觸點(diǎn)”。
2、熱敏干簧繼電器的工作原理和特性
     熱敏干簧繼電器是一種利用熱敏磁性材料檢測(cè)和控制溫度的新型熱敏開(kāi)關(guān)。它由感溫磁環(huán)、恒磁環(huán)、干簧管、導(dǎo)熱安裝片、塑料襯底及其他一些附件組成。熱敏干簧繼電器不用線圈勵(lì)磁，而由恒磁環(huán)產(chǎn)生的磁力驅(qū)動(dòng)開(kāi)關(guān)動(dòng)作。恒磁環(huán)能否向干簧管提供磁力是由感溫磁環(huán)的溫控特性決定的。
3、固態(tài)繼電器（SSR）的工作原理和特性
     固態(tài)繼電器是一種兩個(gè)接線端為輸入端，另兩個(gè)接線端為輸出端的四端器件，中間采用隔離器件實(shí)現(xiàn)輸入輸出的電隔離。
固態(tài)繼電器按負(fù)載電源類(lèi)型可分為交流型和直流型。按開(kāi)關(guān)型式可分為常開(kāi)型和常閉型。按隔離型式可分為混合型、變壓器隔離型和光電隔離型，以光電隔離型為zui多。

二、繼電器主要產(chǎn)品技術(shù)參數(shù)
1、額定工作電壓
  是指繼電器正常工作時(shí)線圈所需要的電壓。根據(jù)繼電器的型號(hào)不同，可以是交流電壓，也可以是直流電壓。
2、直流電阻
  是指繼電器中線圈的直流電阻，可以通過(guò)萬(wàn)能表測(cè)量。
3、吸合電流
  是指繼電器能夠產(chǎn)生吸合動(dòng)作的zui小電流。在正常使用時(shí)，給定的電流必須略大于吸合電流，這樣繼電器才能穩(wěn)定地工作。而對(duì)于線圈所加的工作電壓，一般不要超過(guò)額定工作電壓的1.5倍，否則會(huì)產(chǎn)生較大的電流而把線圈燒毀。
4、釋放電流
         是指繼電器產(chǎn)生釋放動(dòng)作的zui大電流。當(dāng)繼電器吸合狀態(tài)的電流減小到一定程度時(shí)，繼電器就會(huì)恢復(fù)到未通電的釋放狀態(tài)。這時(shí)的電流遠(yuǎn)遠(yuǎn)小于吸合電流。
5、觸點(diǎn)切換電壓和電流
         是指繼電器允許加載的電壓和電流。它決定了繼電器能控制電壓和電流的大小，使用時(shí)不能超過(guò)此值，否則很容易損壞繼電器的觸點(diǎn)。

繼電器是一種電子控制器件，它具有控制系統(tǒng)（又稱(chēng)輸入回路）和被控制系統(tǒng)（又稱(chēng)輸出回路），通常應(yīng)用于自動(dòng)控制電路中，它實(shí)際上是用較小的電流去控制較大電流的一種“自動(dòng)開(kāi)關(guān)”。繼電器的作用是 在電路中起著自動(dòng)調(diào)節(jié)、安全保護(hù)、以弱控強(qiáng)，轉(zhuǎn)換電路等作用。

固態(tài)繼電器（solid state relay，SSR）是利用發(fā)光二極管等發(fā)光元件與一顆光晶體管等光接收元件作成之光耦合器，觸發(fā)硅控整流體或雙向硅控整流器，因此可以接受低壓（DC或AC）信號(hào)輸入，而驅(qū)動(dòng)高壓之輸出，具隔離輸出入及控制高功率輸出之效果。固態(tài)繼電器按負(fù)載電源類(lèi)型可分為交流型和直流型。按開(kāi)關(guān)型式可分為常開(kāi)型和常閉型。按隔離型式可分為混合型、變壓器隔離型和光電隔離型，以光電隔離型為zui多。 固態(tài)繼電器開(kāi)關(guān)速度快、工作頻率高、使用壽命長(zhǎng)、 噪聲低和工作可靠。可取代常規(guī)電磁式繼電器，被廣泛用于數(shù)位程控裝置。

  德國(guó)皮爾茲PILZ繼電器的種類(lèi)和原理@   磁簧繼電器是以線圈產(chǎn)生磁場(chǎng)將磁簧管作動(dòng)之繼電器，為一種線圈傳感裝置。因此磁簧繼電器之特征、小型尺寸、輕量、反應(yīng)速度快、短跳動(dòng)時(shí)間等特性。當(dāng)整塊鐵磁金屬或者其它導(dǎo)磁物質(zhì)與之靠近的時(shí)候，發(fā)生動(dòng)作，開(kāi)通或者閉合電路。由*磁鐵和干簧管組成。*磁鐵、干簧管固定在一個(gè)不導(dǎo)磁也不帶有磁性的支架上。以*磁鐵的南北極的連線為軸線，這個(gè)軸線應(yīng)該與干簧管的軸線重合或者基本重合。由遠(yuǎn)及近的調(diào)整*磁鐵與干簧管之間的距離，當(dāng)干簧管剛好發(fā)生動(dòng)作（對(duì)于常開(kāi)的干簧管，變?yōu)殚]合；對(duì)于常閉的干簧管，變?yōu)閿嚅_(kāi)）時(shí)，將磁鐵的位置固定下來(lái)。這時(shí)，當(dāng)有整塊導(dǎo)磁材料，例如鐵板同時(shí)靠近磁鐵和干簧管時(shí)，干簧管會(huì)再次發(fā)生動(dòng)作，恢復(fù)到?jīng)]有磁場(chǎng)作用時(shí)的狀態(tài)；當(dāng)該鐵板離開(kāi)時(shí)，干簧管即發(fā)生相反方向的動(dòng)作。 磁簧繼電器結(jié)構(gòu)堅(jiān)固，觸點(diǎn)為密封狀態(tài)，耐用性高，可以作為機(jī)械設(shè)備的位置限制開(kāi)關(guān)，也可以用以探測(cè)鐵制門(mén)、窗等是否在位置
