描述

Y60BF
安全柵的主要功能就是限制安全場(chǎng)所的危險(xiǎn)能量進(jìn)入危險(xiǎn)場(chǎng)所，及限制送往危險(xiǎn)場(chǎng)所的電壓和電流。齊納管Z用于限制電壓，當(dāng)回路電壓接近安全限壓值時(shí)，齊納管導(dǎo)通，使齊納管兩端的電壓始終保持在安全限壓值以下。電阻R用于限制電流，當(dāng)電壓被限制后，適當(dāng)選擇電阻值，可將回路電流限制在安全限流值以下。?保險(xiǎn)絲F的作用是防止因齊納管被長(zhǎng)時(shí)間流過的大電流燒斷而導(dǎo)致回路限壓失效。當(dāng)超過安全限壓值的電壓加在回路上時(shí)，齊納管導(dǎo)通，如果沒有保險(xiǎn)絲，流經(jīng)齊納管的電流將無限上升，最終燒斷齊納管，使回路失去限壓。為確?；芈废迚喊踩?，保險(xiǎn)絲的熔斷速度要比齊納管可能被燒斷的速度快十倍。 ?? ? 雙控開關(guān)，是日常生活中常用的一種接線方式，比如樓梯的過道口、走廊、臥室、衛(wèi)生間等，雙控開關(guān)就是為了讓大家可以在不同的地方控制燈泡，控制燈泡的亮度還有就是開和關(guān)，一般的像是臥室的開關(guān)，很多人喜歡設(shè)計(jì)雙控開關(guān)在床頭以及門口的位置，這樣關(guān)燈就方便了，也是比較便利的作用。相比傳統(tǒng)開關(guān)而言，它同時(shí)帶有常開、常閉兩個(gè)觸點(diǎn)，更省時(shí)省力。在房屋裝修時(shí)，雙控開關(guān)接線方式是大家比較關(guān)心的問題，希望大家看了小編介紹的雙控開關(guān)接線圖示例后，可以知道雙控開關(guān)怎么接。在日常生活中，三聯(lián)開關(guān)是很多見的。不管是辦公室或者是其他樓層內(nèi)，總是能看到這樣的開關(guān)。三聯(lián)開關(guān)與雙聯(lián)開關(guān)的接線，區(qū)別在于多了一個(gè)兩位雙聯(lián)開關(guān)，所以我們重點(diǎn)來說一下三聯(lián)開關(guān)接線圖，其余部分與雙聯(lián)開關(guān)的接線是一樣的在這里我們就不多講了。三聯(lián)開關(guān)，簡(jiǎn)單理解就是這個(gè)開關(guān)面板上有3個(gè)開關(guān)，雙控，就是指雙控開關(guān)。三聯(lián)雙控，就是3個(gè)開關(guān)都是雙控開關(guān)三聯(lián)就是上面可以控制三個(gè)不同的電器，比如說上面有兩個(gè)開關(guān)就稱雙聯(lián)，有三位開關(guān)則稱三聯(lián)，雙控是指該開關(guān)是雙控功能的，知道雙控吧，就是可以兩個(gè)開關(guān)控制同一個(gè)地方的電器，一般都是燈了。三聯(lián)雙控就是把兩者結(jié)合在一起。

15天包退換 一年質(zhì)保 大量現(xiàn)貨? 國(guó)內(nèi)實(shí)力庫(kù)存商家


選擇深圳長(zhǎng)欣，選擇放心，售后無憂大量現(xiàn)貨，當(dāng)天順豐發(fā)貨！
主營(yíng)：本特利，英維思，伍德沃德，?？怂共_、西屋、瑞恩、施耐德莫迪康、ABB、AB、西門子、摩托羅拉、GE發(fā)那科、安川、博世力士樂，ACSO，力士樂等各大品牌的DCS系統(tǒng)配件，機(jī)器人系統(tǒng)配件，大型伺服系統(tǒng)備件。

先介紹幾點(diǎn)經(jīng)驗(yàn)。
1、先通讀一遍“系統(tǒng)手冊(cè)”（不管能不能看懂，先了解個(gè)大概，以便學(xué)習(xí)編程時(shí)查找）；
2、由位控邏輯入手，逐漸增加定時(shí)、計(jì)數(shù)等條件，把或、與、非關(guān)系理順；
3、進(jìn)而練習(xí)整數(shù)運(yùn)算、實(shí)數(shù)運(yùn)算、類型轉(zhuǎn)換；
4、量程轉(zhuǎn)換、PID調(diào)節(jié)回路的建立及P、I、D參數(shù)的理解（最好是有個(gè)物理回路驗(yàn)證，比如變頻器+電機(jī)+測(cè)速傳感器）；
5、循環(huán)、順序、跳轉(zhuǎn)等程序控制（盡量避免跳轉(zhuǎn)，非跳不可時(shí)也是跳的越近越好）；
6、中斷、通訊、位置控制....

本人以ABB工業(yè)機(jī)器人配件DSQC系列和Motorola MVME系列，GE 卡件 模塊 驅(qū)動(dòng)器系列為主攻。各位電工朋友可根據(jù)自己的條件選擇適合自己的PLC品牌，由于PLC的基本框架大同小異，學(xué)會(huì)一種至于其它的學(xué)習(xí)起來也就簡(jiǎn)單了。
