產品資(zi)料:

安(an)全繼(ji)電器(qi)是(shi)一個安(an)全回(hui)路(lu)(lu)中所必須(xu)的(de)控制部分，它接受安(an)全輸(shu)入，通(tong)(tong)(tong)過(guo)對內部回(hui)路(lu)(lu)的(de)判(pan)斷，輸(shu)出開(kai)關信號(hao)到(dao)設備的(de)控制回(hui)路(lu)(lu)里。簡(jian)單地說，安(an)全繼(ji)電器(qi)都(dou)是(shi)雙(shuang)通(tong)(tong)(tong)道(dao)信號(hao)型(xing)，只(zhi)有(you)兩個通(tong)(tong)(tong)道(dao)信號(hao)都(dou)正常(chang)時，安(an)全繼(ji)電器(qi)才(cai)能正常(chang)工作(zuo);在工作(zuo)過(guo)程(cheng)中，只(zhi)要其(qi)中任一通(tong)(tong)(tong)道(dao)信號(hao)斷開(kai)，安(an)全繼(ji)電器(qi)都(dou)會停止(zhi)輸(shu)出，直到(dao)兩個通(tong)(tong)(tong)道(dao)信號(hao)都(dou)正常(chang)且復(fu)位后(hou)才(cai)能正常(chang)工作(zuo)。

實際上，為(wei)了(le)方便安全(quan)電(dian)(dian)(dian)(dian)路(lu)的(de)構成，將安全(quan)繼電(dian)(dian)(dian)(dian)器(qi)(qi)和(he)其他(ta)組件組合配套，把基本的(de)緊急停止(zhi)電(dian)(dian)(dian)(dian)路(lu)、安全(quan)電(dian)(dian)(dian)(dian)路(lu)組成電(dian)(dian)(dian)(dian)路(lu)模塊的(de)產品稱為(wei)安全(quan)繼電(dian)(dian)(dian)(dian)器(qi)(qi)模塊。

外部電源電壓的允許公差DC 半導體-20 %/+20 %  

電(dian)(dian)(dian)磁(ci)(ci)式繼(ji)電(dian)(dian)(dian)器一般由鐵芯(xin)、線圈(quan)、銜(xian)鐵、觸(chu)(chu)點簧(huang)片等(deng)組成(cheng)的(de)。只要圈(quan)兩端加上一定的(de)電(dian)(dian)(dian)壓，線圈(quan)中(zhong)就(jiu)會(hui)流過一定的(de)電(dian)(dian)(dian)流，從而產生電(dian)(dian)(dian)磁(ci)(ci)效應，銜(xian)鐵就(jiu)會(hui)在電(dian)(dian)(dian)磁(ci)(ci)力(li)(li)(li)吸(xi)引的(de)作用下克服返(fan)回彈(dan)簧(huang)的(de)拉力(li)(li)(li)吸(xi)向鐵芯(xin)，從而帶動(dong)銜(xian)鐵的(de)動(dong)觸(chu)(chu)點(常(chang)開(kai)觸(chu)(chu)點)與靜(jing)觸(chu)(chu)點(常(chang)閉(bi)觸(chu)(chu)點)吸(xi)合。當(dang)線圈(quan)斷(duan)電(dian)(dian)(dian)后，電(dian)(dian)(dian)磁(ci)(ci)的(de)吸(xi)力(li)(li)(li)也隨之消失，銜(xian)鐵就(jiu)會(hui)在彈(dan)簧(huang)的(de)反作用力(li)(li)(li)返(fan)回原來的(de)位(wei)置，使動(dong)觸(chu)(chu)點與原來的(de)靜(jing)觸(chu)(chu)點釋放(fang)(fang)。這(zhe)樣吸(xi)合、釋放(fang)(fang)，從而達(da)到了在電(dian)(dian)(dian)路中(zhong)的(de)導通、切(qie)斷(duan)的(de)目的(de)

雙重化是(shi)(shi)必要(yao)的(de)，但是(shi)(shi)除此之外，比(bi)如如下幾(ji)個條件(jian)，雙重化電(dian)路的(de)互相(xiang)檢查(cha)，確認所(suo)有安(an)全電(dian)路已(yi)經(jing)斷開一次，必要(yao)時(shi)由作業者操(cao)作便可(ke)以啟動(dong)等(deng)條件(jian)。還有從另一個角度(du)來說，輸(shu)入的(de)開關接線短路或電(dian)線外皮(pi)破損而引起的(de)接地(di)的(de)可(ke)能(neng)性時(shi)，必須預防因此而引起的(de)機器突(tu)然(ran)啟動(dong)。
