6ES5440-8MA22進(jìn)行隔離是防止電流在兩個通訊點(diǎn)之間流動的一-種方法。-般在兩種情況下采用隔離:*
-種情況是,在有可能存在損壞設(shè)備或危害人員的潛在的電流浪涌時。*二種情況是必須避免
存在不同地電位和分裂的接地回路的互連。兩種情形都是采用隔離來避免電流流過,而允許兩
點(diǎn)之間有數(shù)據(jù)或功率傳送。隔離應(yīng)用涉及高電壓、高速/高精度通信、或者長距離通信。普通
的例子如工業(yè)IO系統(tǒng)、傳感器接口、電源/調(diào)節(jié)桿,發(fā)動機(jī)控制/驅(qū)動系統(tǒng)以及儀器儀表。
早期的設(shè)計(jì)除使用變壓器之外,還使用各種模擬隔離放大器,將工廠地面的傳感器電路與
控制室內(nèi)的信號處理系統(tǒng)進(jìn)行隔離。在通道數(shù)量有限及信號帶寬小的應(yīng)用中,目前仍在采用這些放大器。隔離放大器雖然具有高可靠性和高精度,但受限于信號帶寬50kHz。 其老舊的技
術(shù)要求較小+4V的電源,不支持目前的3V及以下的低電壓應(yīng)用。此外,其制造過程涉及輸入
和輸出部分單獨(dú)制作,異常電路匹配的激光微調(diào),以及在兩部分間安裝隔離電容,使這些器件
相當(dāng)昂貴。
工業(yè)自動控制中的許多數(shù)據(jù)采集系統(tǒng)采用多輸入通道模數(shù)轉(zhuǎn)換器(ADC)捕獲多個模擬輸入
的輸入數(shù)據(jù)(被測物理量)。6ES5440-8MA22 絕大多數(shù)A-SADC都具有串行接口來減小封裝尺寸和占板面積。串
行接口的復(fù)雜性在于需要的慢速控制信號數(shù)不同,如片選、功率降低、增益及速度設(shè)定以及多
路器尋址。不過,所有串行接口都具有時鐘信號和輸出數(shù)據(jù)(轉(zhuǎn)換)高速傳輸線。因?yàn)樾?br>號獲取和調(diào)理發(fā)生在ADC內(nèi)部,將傳感器電路與信號處理電路隔離的較佳位置是在采用數(shù)字
隔離器的數(shù)字接口處。如前所述,因?yàn)榻涌趶?fù)雜,隔離器必須能夠傳輸高速ADC 轉(zhuǎn)換,
同時也要能傳輸?shù)退倏刂菩盘枴?br>
圖是基于一種電容性隔離屏障技術(shù)的隔離器。6ES5440-8MA22 此器件由兩個數(shù)據(jù)通道組成:一個是高頻
通道(HF),帶寬從100 kHz到150MHz;另一個是低頻通道(LF),覆蓋范圍從100 kHz到直
流。
原則上來說,一個單端輸入信號進(jìn)入HF通道之后被輸入端的非門分離為一-微分信號。隨
后的電容電阻網(wǎng)絡(luò)將此信號微分為瞬變信號,然后再通過兩個比較器轉(zhuǎn)換成微分脈沖。比較器
輸出驅(qū)動一個‘或非門跳轉(zhuǎn),其輸出進(jìn)入一-輸出多路器。跳轉(zhuǎn)的輸出驅(qū)動處的一-精密邏輯(DCL)
測量信號瞬變之間的間隔。如果兩個連續(xù)瞬變的間隔**過某- -時間限(如在低頻率信號時),
DCL驅(qū)使輸出多路器從高頻通道轉(zhuǎn)向低頻通道。因?yàn)榈皖l輸入信號需要內(nèi)部電容為受限制的
大容量值,這些信號用一內(nèi)部振蕩器的載波頻率進(jìn)行寬調(diào)制,這樣,得到能通過容性屏障的高
頻信號。調(diào)制輸入時,需要一個低通濾波器(LPF)將高頻載波從實(shí)際數(shù)據(jù)中除掉,然后再到達(dá)
輸出多路器。圖2和圖3給出了高頻通道和低頻通道及相應(yīng)的代表性波形。
