6SL3055-0AA00-4CA5接地是提高電子設(shè)備電磁兼容性（EMC）的有效手段之一。正確的接地，既能抑制電磁干擾的影響，又能抑制設(shè)備向外發(fā)出干擾；而錯(cuò)誤的接地，反而會(huì)引入嚴(yán)重的干擾信號(hào)，使PLC系統(tǒng)將無法正常工作。PLC控制系統(tǒng)的地線包括系統(tǒng)地、屏蔽地、交流地和保護(hù)地等。接地系統(tǒng)混亂對(duì)PLC系統(tǒng)的干擾主要是各個(gè)接地點(diǎn)電位分布不均，不同接地點(diǎn)間存在地電位差，引起地環(huán)路電流，影響系統(tǒng)正常工作。例如電纜屏蔽層必須一點(diǎn)接地，如果電纜屏蔽層兩端A、B都接地，就存在地電位差，有電流流過屏蔽層，當(dāng)發(fā)生異常狀態(tài)加雷擊時(shí)，地線電流將更大。此外，屏蔽層、接地線和大地有可能構(gòu)成閉合環(huán)路，在變化磁場(chǎng)的作用下，屏蔽層內(nèi)有會(huì)出現(xiàn)感應(yīng)電流，通過屏蔽層與芯線之間的耦合，干擾信號(hào)回路。若系統(tǒng)地與其它接地處理混亂，所產(chǎn)生的地環(huán)流可能在地線上產(chǎn)生不等電位分布，影響PLC內(nèi)邏輯電路和模擬電路的正常工作。PLC工作的邏輯電壓干擾容限較低，邏輯地電位的分布干擾容易影響PLC的邏輯運(yùn)算和數(shù)據(jù)存儲(chǔ)，造成數(shù)據(jù)混亂、程序跑飛或死機(jī)。模擬地電位的分布將導(dǎo)致測(cè)量精度下降，引起對(duì)信號(hào)測(cè)控的嚴(yán)重失真和誤動(dòng)作。主要由系統(tǒng)內(nèi)部元器件及電路間的相互電磁輻射產(chǎn)生，如邏輯電路互輻射及其對(duì)模擬電路的影響，模擬地與邏輯地的相互影響及元器件間的相互不匹配使用等。這都屬于PLC制造廠對(duì)系統(tǒng)內(nèi)部進(jìn)行電磁兼容設(shè)計(jì)的內(nèi)容，比較復(fù)雜，作為應(yīng)用部門是無法改變，可不必過多考慮，但要選擇具有較多應(yīng)用實(shí)績(jī)或經(jīng)過考驗(yàn)的系統(tǒng)。產(chǎn)品承諾：保 證 全新原裝進(jìn)口,保 證 安全準(zhǔn)時(shí)發(fā)貨，保 證售后服務(wù)質(zhì)量，優(yōu)勢(shì)價(jià)格，大量現(xiàn)貨。主營(yíng)DCS系統(tǒng)配件機(jī)器人系統(tǒng)配件大型伺服系統(tǒng)配件品牌：ABB   ,AB  ,GE,FOXBORO,本特利，英維思，伍德沃德，西屋，瑞恩，施耐德，西門子，摩托羅拉，安川。力士樂。ACSO，橫河等進(jìn)口品牌。 專業(yè)銷售進(jìn)口DCS  PLC系統(tǒng)備件模塊Triconex Siemens Yaskawa ABB GE Ovation AB Foxboro Motorola Schneider XYCOM KUKA   專業(yè)銷售進(jìn)口DCS  PLC系統(tǒng)備件模塊 15天包退換 一年質(zhì)保 大量現(xiàn)貨  國(guó)內(nèi)實(shí)力庫存商家Siemens Simatic 7 Moby STG-E 6GT2303-1AA00 Psion WorkSiemens Sinumerik OP 31 6FC5203-0AB10-0AA0 + MMC 101ABB C5 Roboter TBK-02 E3E032244 3E032244Siemens Sinumerik Sirotec 6FX1123-1BA01 FBG InterfaceSiemens Sinumerik System 8 MS320 6FX1113-6AA00 MS321-AFANUC Servo Motor Control Unit SVM1-40L A06B-6069-H104Siemens Simatic S5 WF723A 6FM1723-3AA10 WF723 Vers. 09Siemens Simatic S7 OP177B 6AV6642-0DC01-1AX1 NEU V17Siemens Simatic S7 OP177B 6AV6642-0DC01-1AX1 NEU V17ABB DCS 400 Digital DC Drive DCS402.0025 Rev.
