現(xiàn)在市場有那么多品牌的隔離器，價格參差不齊，該怎么選擇呢？隔離器位于二個系統(tǒng)通道之間，所以選擇隔離器首先要確定輸入輸出功能，同時要使隔離器輸入輸出模式（電壓型、電流型、環(huán)路供電型等）適應前后端通道接口模式。此外尚有精度﹑功耗﹑噪音﹑絕緣強度﹑總線通訊功能等許多重要參數(shù)涉及產(chǎn)品性能，例如：噪音與精度有關(guān)、功耗熱量與可靠性有關(guān)，這些需要使用者慎選。總之，適用、可靠、產(chǎn)品性價比是選擇隔離器的主要原則。
　　隨著科學技術(shù)的發(fā)展，PLC在工業(yè)控制中的應用越來越廣泛。PLC控制系統(tǒng)的可靠性直接影響到工業(yè)企業(yè)的安全生產(chǎn)和經(jīng)濟運行，系統(tǒng)的抗*能力是關(guān)系到整個系統(tǒng)可靠運行的關(guān)鍵。自動化系統(tǒng)中所使用的各種類型PLC，有的是集中安裝在控制室，有的是安裝在生產(chǎn)現(xiàn)場和各電機設(shè)備上，它們大多處在強電電路和強電設(shè)備所形成的惡劣電磁環(huán)境中。要提高PLC控制系統(tǒng)可靠性，設(shè)計人員只有預先了解各種*才能有效保證系統(tǒng)可靠運行。
