產品資料:

安(an)(an)(an)全(quan)繼(ji)電(dian)(dian)器(qi)是一(yi)個安(an)(an)(an)全(quan)回(hui)路(lu)中所必須的(de)控制(zhi)部(bu)分，它接受安(an)(an)(an)全(quan)輸(shu)入，通(tong)(tong)過對(dui)內部(bu)回(hui)路(lu)的(de)判斷(duan)，輸(shu)出(chu)開關信號(hao)(hao)到設(she)備的(de)控制(zhi)回(hui)路(lu)里(li)。簡單地(di)說，安(an)(an)(an)全(quan)繼(ji)電(dian)(dian)器(qi)都是雙(shuang)通(tong)(tong)道(dao)(dao)(dao)(dao)信號(hao)(hao)型，只有兩個通(tong)(tong)道(dao)(dao)(dao)(dao)信號(hao)(hao)都正(zheng)常時，安(an)(an)(an)全(quan)繼(ji)電(dian)(dian)器(qi)才(cai)能(neng)正(zheng)常工(gong)作;在工(gong)作過程中，只要其中任一(yi)通(tong)(tong)道(dao)(dao)(dao)(dao)信號(hao)(hao)斷(duan)開，安(an)(an)(an)全(quan)繼(ji)電(dian)(dian)器(qi)都會停止輸(shu)出(chu)，直到兩個通(tong)(tong)道(dao)(dao)(dao)(dao)信號(hao)(hao)都正(zheng)常且復(fu)位后才(cai)能(neng)正(zheng)常工(gong)作。

實(shi)際(ji)上，為(wei)了(le)方(fang)便(bian)安全(quan)電(dian)(dian)路(lu)的(de)構成，將安全(quan)繼電(dian)(dian)器和其他(ta)組(zu)件組(zu)合配套，把基(ji)本的(de)緊急停(ting)止電(dian)(dian)路(lu)、安全(quan)電(dian)(dian)路(lu)組(zu)成電(dian)(dian)路(lu)模(mo)塊(kuai)的(de)產品稱為(wei)安全(quan)繼電(dian)(dian)器模(mo)塊(kuai)。

外部電源電壓的允許公差DC 半導體-20 %/+20 %  

電(dian)(dian)磁(ci)式(shi)繼(ji)電(dian)(dian)器(qi)一(yi)般由鐵芯、線圈、銜(xian)鐵、觸(chu)點(dian)(dian)(dian)簧(huang)片等組成(cheng)的(de)(de)。只要(yao)圈兩端加上一(yi)定的(de)(de)電(dian)(dian)壓，線圈中就(jiu)會(hui)流過一(yi)定的(de)(de)電(dian)(dian)流，從而產生電(dian)(dian)磁(ci)效應，銜(xian)鐵就(jiu)會(hui)在電(dian)(dian)磁(ci)力(li)吸(xi)引的(de)(de)作(zuo)用下克服(fu)返回彈(dan)簧(huang)的(de)(de)拉(la)力(li)吸(xi)向鐵芯，從而帶(dai)動(dong)銜(xian)鐵的(de)(de)動(dong)觸(chu)點(dian)(dian)(dian)(常開觸(chu)點(dian)(dian)(dian))與靜觸(chu)點(dian)(dian)(dian)(常閉觸(chu)點(dian)(dian)(dian))吸(xi)合。當線圈斷電(dian)(dian)后，電(dian)(dian)磁(ci)的(de)(de)吸(xi)力(li)也隨之消失(shi)，銜(xian)鐵就(jiu)會(hui)在彈(dan)簧(huang)的(de)(de)反作(zuo)用力(li)返回原(yuan)來(lai)的(de)(de)位(wei)置，使動(dong)觸(chu)點(dian)(dian)(dian)與原(yuan)來(lai)的(de)(de)靜觸(chu)點(dian)(dian)(dian)釋放。這樣吸(xi)合、釋放，從而達到了在電(dian)(dian)路中的(de)(de)導通、切斷的(de)(de)目的(de)(de)

雙重(zhong)(zhong)化(hua)(hua)是必(bi)要(yao)的(de)(de)，但是除此之外(wai)，比如如下(xia)幾個條件，雙重(zhong)(zhong)化(hua)(hua)電(dian)路(lu)的(de)(de)互相檢查，確認所有(you)安全電(dian)路(lu)已經斷開一次(ci)，必(bi)要(yao)時(shi)由(you)作業(ye)者操作便可以啟動(dong)等(deng)條件。還有(you)從另一個角度來說，輸入的(de)(de)開關接線短路(lu)或電(dian)線外(wai)皮(pi)破損而(er)引起的(de)(de)接地的(de)(de)可能性時(shi)，必(bi)須(xu)預防因此而(er)引起的(de)(de)機器突然啟動(dong)。
