德國(guó)PILZ安全繼電器，安全開關(guān)，技術(shù)參數(shù)

皮爾茲安全繼電器主要有兩個(gè)作用:一是隔離作用;二是增加輔助接點(diǎn).在實(shí)際應(yīng)用中增加接點(diǎn)比較少,因?yàn)楝F(xiàn)在的接觸器可以另加很多對(duì)輔助接點(diǎn),而且動(dòng)作也可靠,所以沒有必要在一般控制日路中增加輔助繼電器.而隔離作用在目前的控制中用得是比較多的.筆者以為主要有兩個(gè)方面的隔離:一是將一個(gè)控制回路分隔為兩個(gè)甚至更多的相對(duì)獨(dú)立的回路;二是將強(qiáng)電量的模擬信號(hào)通過(guò)中間繼電器轉(zhuǎn)化為開關(guān)量侑源或無(wú)源).這里強(qiáng)調(diào)的不是這些繼電器的作用,而是要通過(guò)工程實(shí)例,對(duì)中間繼電器應(yīng)用中的技術(shù)問(wèn)題做出分析及提出解決的對(duì)策.
安全繼電器顧名思義要安全,它是一個(gè)安全回路中所必須的控制部分(安全回路包括安全輸入,控制器,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)通過(guò)內(nèi)部回路的判斷,確定性的輸出開關(guān)信號(hào)到設(shè)備的控制回路里.它的輸入輸出一般都是冗余的,并且觸點(diǎn)都是強(qiáng)制導(dǎo)向的開關(guān).
其實(shí)安全繼電器說(shuō)白了就是把2-4個(gè)繼電器混在了一起,各自的觸點(diǎn)很多是互鎖的,這樣就可以有效地監(jiān)控外部回路的觸點(diǎn)是否熔接,或者有沒有短路等現(xiàn)象.
而PILZ安全繼電器可以監(jiān)控功率、電流、電壓、接地故障、相位序列;同時(shí)也可以用來(lái)控制急停、安全門、光柵、安全地毯、雙手控制等,而且PILZ安全繼電器操作簡(jiǎn)便、產(chǎn)品部件符合標(biāo)準(zhǔn)與規(guī)范(如EN954-1)而且通過(guò)zui少一家以上的機(jī)構(gòu)測(cè)試,并予以認(rèn)證.帶有插入終端的單元,可確保更快的試運(yùn)行,有zui小的空間,有zui高的安全等級(jí),*的性價(jià)比,通用電源的低存儲(chǔ)成本.可用于所有安全功能,如監(jiān)控緊急停止,安全門,光柵等.
皮爾茲安全繼電器工作特性:
作為控制元件,繼電器有如下四個(gè)特點(diǎn):皮爾茲安全繼電器工作原理及技術(shù)參數(shù)
1)擴(kuò)大控制范圍.例如,多觸點(diǎn)繼電器控制信號(hào)達(dá)到某一定值時(shí),可以按觸點(diǎn)組的不同形式,同時(shí)換接、開斷、接通多路電路.
2)放大.例如中間繼電器等,只用一個(gè)很微小的控制量,
就可以控制很大功率的電路.
3)綜合信號(hào).例如,當(dāng)多個(gè)控制信號(hào)按規(guī)定的形式輸入多繞組繼電器時(shí),經(jīng)過(guò)比較綜合,達(dá)到預(yù)定的控制效果.
4)自動(dòng)、遙控、監(jiān)測(cè).例如,自動(dòng)裝置上的繼電器與其他電器一起,可以組成程序控制線路,從而實(shí)現(xiàn)自動(dòng)化運(yùn)行.皮爾茲安全繼電器工作原理及技術(shù)參數(shù)
4 皮爾茲安全繼電器應(yīng)用實(shí)例:以膠帶機(jī)的自動(dòng)控制為例,介紹中間繼電器的隔離作用
工作原理是將一個(gè)輸入信號(hào)變成一個(gè)或多個(gè)輸出信號(hào)的電子元件.它的輸入信號(hào)為線圈的通電或斷電.它的輸出是觸頭的動(dòng)作(所帶常開點(diǎn)閉合,常閉點(diǎn)打開),它的觸點(diǎn)接在其他控制回路中,通過(guò)觸點(diǎn)的變化導(dǎo)致控制回路發(fā)生變化(例如導(dǎo)通或截止),從而實(shí)現(xiàn)既定的控制或保護(hù)的目的.在此過(guò)程中,繼電器主要起了傳遞信號(hào)的作用
