一般工業控制系統既包括弱電控制部分，又包括強電控制部分。為了使兩者之間既保持控制信號，又要隔絕電氣方面的，即實行弱電和強電隔離，是保證系統工作穩定，設備與操作人員安全的重要措施。

　　電氣隔離目的之一是從電路上把干擾源和易干擾的部分隔離開來，從而達到隔離現場干擾的目的。

　　一、信號隔離

　　信號的隔離目的之一是把引進的干擾通道切斷，使測控裝置與現場僅保持信號，不直接發生電的。工控裝置與現場信號之間常用的隔離方式有光電隔離、脈沖變壓器隔離、繼電器隔離和布線隔離等。

　　1.光電隔離

　　光電隔離是由光電耦合器件來完成的。其輸入端配置發光源，輸出端配置受光器，因而輸入和輸出在電氣上是完全隔離的。由于光電耦合器的輸入阻抗(100Ω～1kΩ)與一般干擾源的阻抗(105～106Ω)相比較小，因此分壓在光電耦合器的輸入端的干擾電壓較小，它所能提供的電流并不大，不易使半導體二極管發光。另外光電耦合器的隔離電阻很大(約1012Ω)、隔離電容很小(約幾個pF)，所以能阻止電路性耦合產生的電磁干擾，被控設備的各種干擾很難反饋到輸入系統。

　　光電耦合器把輸入信號與內部電路隔離開來，或者是把內部輸出信號與外部電路隔離開來，如圖1所示。開關量輸入電路接入光電耦合器后，由于光電耦合器的隔離作用，使夾雜在輸入開關量中的各種干擾脈沖都被擋在輸入回路的一側。由于光電耦合器不是將輸入側和輸出側的電信號進行直接耦合，而是以光為媒介進行耦合，具有較高的電氣隔離和抗干擾能力。

　　目前，大多數光電耦合器件的隔離電壓都在2.5kV以上，有些器件達到了8kV，既有高壓大電流大功率光電耦合器件，又有高速高頻光電耦合器件(頻率高達10MHz)。常用的器件如4N25，其隔離電壓為5.3kV；6N137，其隔離電壓為3kV，頻率在10MHz以上。

　　2.脈沖變壓器隔離

　　脈沖變壓器的匝數較少，而且一次繞組和二次繞組分別繞于鐵氧體磁芯的兩側，這種工藝使得它的分布電容特小，僅為幾個pF，所以可作為脈沖信號的隔離元件。脈沖變壓器傳遞輸入、輸出脈沖信號時，不傳遞直流分量，PLC使用的數字量信號輸入/輸出的控制設備不要求傳遞直流分量，因而在工控系統中得到了廣泛的應用。

　　圖2是脈沖變壓器的應用實例。電路的外部信號經RC濾波電路和雙向穩壓管抑制常模噪聲干擾，然后輸入脈沖

　　變壓器的一次側。為了防止過高的對稱信號擊穿電路元件，脈沖變壓器的二次側輸出電壓被穩壓管限幅后進入測控系統內部。一般地說，脈沖變壓器的信號傳遞頻率在1kHz～1MHz之間，新型的高頻脈沖變壓器的傳遞頻率可達到10MHz。

　　3.繼電器隔離

　　繼電器的線圈和觸點沒有電氣上的，因此，可利用繼電器的線圈接受信號，利用觸點發送和輸出控制信號，從而避免強電和弱電信號之間的直接接觸，實現了抗干擾隔離。

　　圖3是繼電器輸出隔離的實例示意圖。在該電路中，通過繼電器把低壓直流與高壓交流隔離開來，使高壓交流側的干擾無法進入低壓直流側。

　　4.布線隔離

　　將微弱信號電路與易產生噪聲污染的電路分開布線，zui基本的要求是信號線路必須和強電控制線路、電源線路分開走線，而且相互間要保持一定的距離。配線時應區別分開交流線、直流穩壓電源線、數字信號線、模擬信號線、感性負載驅動線等。配線間隔越大，配線越短，則噪聲影響越小。但是，實際設備的內外空間是有限的，配線間隔不可能太大，只要能維持zui低限度的間隔距離便可。

　　附表列出了信號線和動力線之間應保持的zui小間距。如果受環境條件的限制，信號線不能與高壓線和動力線等離得足夠遠時，就得采用諸如信號線路接電容器等各種抑制電磁感應噪聲的措施。
