未曾經(jīng)歷 如何懂得？ 表面越是簡單 里面越有學(xué)問！ 好PLC用了才知道

一般I／O模塊的價格占PLC價格的一半以上。PLC的I／O模塊有開關(guān)量I／O模塊、
模擬量I／O模塊及各種特殊功能模塊等。不同的I／O模塊，其電路及功能也不
同，直接影響PLC的應(yīng)用范圍和價格，應(yīng)當根據(jù)實際需要加以選擇。
（一）開關(guān)量I／O模塊的選擇
1. 開關(guān)量輸入模塊的選擇
開關(guān)量輸入模塊是用來接收現(xiàn)場輸入設(shè)備的開關(guān)信號，將信號轉(zhuǎn)換為PLC內(nèi)部接
受的低電壓信號，并實現(xiàn)PLC內(nèi)、外信號的電氣隔離。選擇時主要應(yīng)考慮以下幾
個方面：
1）輸入信號的類型及電壓等級
開關(guān)量輸入模塊有直流輸入、交流輸入和交流／直流輸入三種類型。選擇時主要
根據(jù)現(xiàn)場輸入信號和周圍環(huán)境因素等。直流輸入模塊的延遲時間較短，還可以直
接與接近開關(guān)、光電開關(guān)等電子輸入設(shè)備連接；交流輸入模塊可靠性好，適合于
有油霧、粉塵的惡劣環(huán)境下使用。
開關(guān)量輸入模塊的輸入信號的電壓等級有：直流5Ｖ、12Ｖ、24Ｖ、48Ｖ、60Ｖ等；
交流110Ｖ、220Ｖ等。選擇時主要根據(jù)現(xiàn)場輸入設(shè)備與輸入模塊之間的距離來考
慮。一般5Ｖ、12Ｖ、24Ｖ用于傳輸距離較近場合，如5Ｖ輸入模塊最遠不得超過
１０米。距離較遠的應(yīng)選用輸入電壓等級較高的模塊。
