特點一覽:

繼(ji)電(dian)(dian)(dian)器(qi)(qi)(qi)線(xian)圈(quan)在(zai)(zai)電(dian)(dian)(dian)路中用一(yi)個(ge)(ge)長(chang)方(fang)框(kuang)符號表(biao)示(shi)(shi)，如果繼(ji)電(dian)(dian)(dian)器(qi)(qi)(qi)有兩(liang)個(ge)(ge)線(xian)圈(quan)，就畫(hua)兩(liang)個(ge)(ge)并列(lie)的(de)長(chang)方(fang)框(kuang)。同(tong)(tong)時在(zai)(zai)長(chang)方(fang)框(kuang)內或長(chang)方(fang)框(kuang)旁標(biao)上(shang)繼(ji)電(dian)(dian)(dian)器(qi)(qi)(qi)的(de)文(wen)字(zi)符號“J"。繼(ji)電(dian)(dian)(dian)器(qi)(qi)(qi)的(de)觸(chu)點(dian)有兩(liang)種表(biao)示(shi)(shi)方(fang)法：一(yi)種是把它們直接畫(hua)在(zai)(zai)長(chang)方(fang)框(kuang)一(yi)側，這種表(biao)示(shi)(shi)法較(jiao)為直觀。另一(yi)種是按照電(dian)(dian)(dian)路連(lian)接的(de)需要，把各個(ge)(ge)觸(chu)點(dian)分別(bie)畫(hua)到各自的(de)控制電(dian)(dian)(dian)路中，通常在(zai)(zai)同(tong)(tong)一(yi)繼(ji)電(dian)(dian)(dian)器(qi)(qi)(qi)的(de)觸(chu)點(dian)與線(xian)圈(quan)旁分別(bie)標(biao)注上(shang)相(xiang)同(tong)(tong)的(de)文(wen)字(zi)符號，并將觸(chu)點(dian)組編上(shang)號碼，以示(shi)(shi)區別(bie)。

PNOZ X 安(an)全(quan)(quan)繼電(dian)器(qi)的可靠性(xing)(xing)和(he)穩健性(xing)(xing)久經考驗。它們應(ying)用(yong)范(fan)圍廣泛用(yong)，且適應(ying)多樣(yang)化的安(an)全(quan)(quan)應(ying)用(yong)。每項安(an)全(quan)(quan)功能(neng)使(shi)用(yong)一個(ge) PNOZ X 安(an)全(quan)(quan)繼電(dian)器(qi)。它的技術(shu)特性(xing)(xing)是采用(yong)無(wu)源和(he)使(shi)用(yong)雙繼電(dian)器(qi)技術(shu)的機電(dian)式(shi)觸點(dian)。尺寸范(fan)圍為 22.5 至 90 mm，觸點(dian)數量從兩個(ge)到八個(ge)不等。

安全繼(ji)電器（獨立式），輸(shu)入：帶(dai)/不帶(dai)觸點間(jian)短路檢測功能(neng) 的1/2通(tong)道接(jie)線，輸(shu)出：3 N/O, 1 N/C, 自(zi)動(dong)/手動(dong)啟動(dong)，UB=24 V AC/DC，寬(kuan)度：22.5 mm，可插拔 螺絲式端(duan)子，監控(kong)急(ji)停裝置和安全門。

是一(yi)種(zhong)(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)子控(kong)(kong)制(zhi)(zhi)器(qi)(qi)件(jian)，它(ta)具有控(kong)(kong)制(zhi)(zhi)系(xi)統（又(you)稱輸入(ru)回路(lu)(lu)）和被控(kong)(kong)制(zhi)(zhi)系(xi)統（又(you)稱輸出回路(lu)(lu)），通常(chang)應用于自動(dong)(dong)控(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)中，它(ta)實際上是用較小的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)去控(kong)(kong)制(zhi)(zhi)較大電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)一(yi)種(zhong)(zhong)“自動(dong)(dong)開關"。故在電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)中起著(zhu)自動(dong)(dong)調節、安(an)全保護、轉換電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)等作用。繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)線圈在電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)中用一(yi)個(ge)長方框符號(hao)(hao)表示(shi)，如(ru)果(guo)繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)有兩個(ge)線圈，就(jiu)畫兩個(ge)并列的(de)(de)(de)長方框。同(tong)時在長方框內或長方框旁標(biao)上繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)(de)(de)文字符號(hao)(hao)“J"。繼(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)(de)(de)觸點(dian)有兩種(zhong)(zhong)表示(shi)方法(fa)：一(yi)種(zhong)(zhong)是把它(ta)們(men)直接畫在長方框一(yi)側，這種(zhong)(zhong)表示(shi)法(fa)較為直觀。

電(dian)(dian)(dian)磁(ci)繼電(dian)(dian)(dian)器一般由鐵(tie)芯、線(xian)(xian)圈、銜鐵(tie)、觸(chu)點(dian)(dian)等(deng)組成的(de)(de)(de)(de)。只要在線(xian)(xian)圈兩端加(jia)上一定的(de)(de)(de)(de)電(dian)(dian)(dian)壓(ya)，線(xian)(xian)圈中就(jiu)會流過(guo)一定的(de)(de)(de)(de)電(dian)(dian)(dian)流，從(cong)而(er)(er)產(chan)生(sheng)電(dian)(dian)(dian)磁(ci)效(xiao)應，銜鐵(tie)就(jiu)會在電(dian)(dian)(dian)磁(ci)力(li)吸(xi)引(yin)的(de)(de)(de)(de)作用(yong)下克服返(fan)回(hui)彈(dan)簧(huang)的(de)(de)(de)(de)拉力(li)吸(xi)向鐵(tie)芯，從(cong)而(er)(er)帶動銜鐵(tie)的(de)(de)(de)(de)動觸(chu)點(dian)(dian)與(yu)靜(jing)(jing)觸(chu)點(dian)(dian)（常開(kai)(kai)觸(chu)點(dian)(dian)）吸(xi)合(he)。當線(xian)(xian)圈斷(duan)電(dian)(dian)(dian)后，電(dian)(dian)(dian)磁(ci)的(de)(de)(de)(de)吸(xi)力(li)也隨之消失，銜鐵(tie)就(jiu)會在彈(dan)簧(huang)的(de)(de)(de)(de)反作用(yong)力(li)返(fan)回(hui)原來的(de)(de)(de)(de)位置(zhi)，使(shi)動觸(chu)點(dian)(dian)與(yu)原來的(de)(de)(de)(de)靜(jing)(jing)觸(chu)點(dian)(dian)（常閉觸(chu)點(dian)(dian)）釋(shi)放。這樣(yang)吸(xi)合(he)、釋(shi)放，從(cong)而(er)(er)達(da)到了在電(dian)(dian)(dian)路中的(de)(de)(de)(de)導通、切(qie)斷(duan)的(de)(de)(de)(de)目的(de)(de)(de)(de)。對(dui)于繼電(dian)(dian)(dian)器的(de)(de)(de)(de)“常開(kai)(kai)、常閉"觸(chu)點(dian)(dian)，可以這樣(yang)來區分(fen)：繼電(dian)(dian)(dian)器線(xian)(xian)圈未通電(dian)(dian)(dian)時(shi)處(chu)于斷(duan)開(kai)(kai)狀(zhuang)態的(de)(de)(de)(de)靜(jing)(jing)觸(chu)點(dian)(dian)，稱為“常開(kai)(kai)觸(chu)點(dian)(dian)"；處(chu)于接通狀(zhuang)態的(de)(de)(de)(de)靜(jing)(jing)觸(chu)點(dian)(dian)稱為“常閉觸(chu)點(dian)(dian)"。繼電(dian)(dian)(dian)器一般有兩股電(dian)(dian)(dian)路，為低壓(ya)控制電(dian)(dian)(dian)路和高壓(ya)工(gong)作電(dian)(dian)(dian)路。
