● 動力線、控制線以及PLC的電源線和I/O線應(yīng)分別配線,隔離變壓器與PLC和I/O之間應(yīng)采用雙膠線連接。將PLC的IO線和大功率線分開走線,如必須在同一線槽內(nèi),分開捆扎交流線、直流線,若條件允許,分槽走線好,這不僅能使其有盡可能大的空間距離,并能將降到低限度。 ● PLC應(yīng)遠(yuǎn)離強(qiáng)源如電焊機(jī)、大功率硅整流裝置和大型動力設(shè)備,不能與高壓電器安裝在同一個開關(guān)柜內(nèi)。在柜內(nèi)PLC應(yīng)遠(yuǎn)離動力線(二者之間距離應(yīng)大于200mm)。與PLC裝在同一個柜子內(nèi)的電感性負(fù)載,如功率較大的繼電器、器的線圈,應(yīng)并聯(lián)RC消弧電路。 ● PLC的輸入與輸出好分開走線,開關(guān)量與模擬量也要分開敷設(shè)。模擬量的傳送應(yīng)采用屏蔽線,屏蔽層應(yīng)一端或兩端接地,接地電阻應(yīng)小于屏蔽層電阻的1/10. ● 交流輸出線和直流輸出線不要用同一根電纜,輸出線應(yīng)盡量遠(yuǎn)離高壓線和動力線,避免并行。
