詳細(xì)介紹
PILZ皮爾茲安全繼電器是由數(shù)個(gè)繼電器與電路組合而成,為的是要能互補(bǔ)相互的反常缺點(diǎn),達(dá)到準(zhǔn)確且低誤動(dòng)作的繼電器完整功用,使其失誤和失效值愈低,安全要素則愈高,因而需規(guī)劃出多種安全繼電器以維護(hù)不一樣等級(jí)機(jī)械,首要方針在維護(hù)露出於不一樣等級(jí)之危險(xiǎn)性的機(jī)械操作人員。

安全繼電器與通常繼電器的首要不一樣在哪里?
所謂“安全繼電器”并不是“沒(méi)有毛病的繼電器”,而是發(fā)作毛病時(shí)做出有規(guī)則的動(dòng)作,它具有強(qiáng)行導(dǎo)向接點(diǎn)構(gòu)造,如果發(fā)作接點(diǎn)熔結(jié)景象時(shí)也能確保安全,這一點(diǎn)同通常繼電器*不一樣。
安全繼電器用在何處呢?
用在帶有承認(rèn)機(jī)器安全的輸入,承認(rèn)安全后,給接觸器等的輸入進(jìn)行操控的安全電路的規(guī)劃上。
Q:對(duì)安全電路的請(qǐng)求
1、在緊迫中止免除時(shí),機(jī)器不能出現(xiàn)俄然再發(fā)動(dòng)
2、如果機(jī)器安全電路發(fā)作毛病時(shí),能夠中止機(jī)器動(dòng)力電源
3、安全電路發(fā)作毛病時(shí),機(jī)器不能再發(fā)動(dòng)
像安全開(kāi)關(guān)、光幕等承認(rèn)安全的輸入,無(wú)法做到上述功用,那么,怎樣才能做到安全電路呢?時(shí)分兩層電路就能夠了?
A:單靠?jī)蓪踊遣豢傻摹?/span>
兩層化是必要的,可是除此之外,比備如下幾個(gè)條件,兩層化電路的相互檢查,承認(rèn)一切安全電路現(xiàn)已斷開(kāi)一次,必要時(shí)由作業(yè)者操作便能夠發(fā)動(dòng)等條件。還有從另一個(gè)角度來(lái)說(shuō),輸入的開(kāi)關(guān)接線短路或電線外皮破損而導(dǎo)致的接地的可能性時(shí),有必要防止因而而導(dǎo)致的機(jī)器俄然發(fā)動(dòng)。
實(shí)際上,為了便利安全電路的構(gòu)成,將安全繼電器和其他組件組合配套,把根本的緊迫中止電路、安全電路構(gòu)成電路模塊的商品稱為安全繼電器模塊。
皮爾茲安全繼電器PNOZX124VDC工作原理
安全繼電器望文生義要安全,它是一個(gè)安全回路中所有必要的操控有些(安全回路包含安全輸入,操控器,安全輸出),安全繼電器接受了安全輸入(比方說(shuō)安全光幕、安全門鎖)經(jīng)過(guò)內(nèi)部回路的判別,確定性的輸出開(kāi)關(guān)信號(hào)到設(shè)備的操控回路里。它的輸入輸出通常都是冗余的,并且觸點(diǎn)都是強(qiáng)行導(dǎo)向的開(kāi)關(guān)。
本來(lái)安全繼電器說(shuō)白了就是把2-4個(gè)繼電器混在了一同,各自的觸點(diǎn)很多是互鎖的,這么就能夠有效地監(jiān)控外部回路的觸點(diǎn)是不是熔接,或許有沒(méi)有短路等景象。
