1756-IH16I/ABPLC模塊
在眾多生產(chǎn)領(lǐng)域中,經(jīng)常需要對貯槽、貯罐、水池等容器中的液位進行監(jiān)控,以往常采用傳統(tǒng)的繼電器接觸控制,使用硬連接電器多,可靠性差,自動化程度不高,目前已有許多企業(yè)采用*控制器對傳統(tǒng)接觸控制進行改造,大大提高了控制系統(tǒng)的可靠性和自控程度,為企業(yè)提供了更可靠的生產(chǎn)保障。本文在此介紹一種采用可編程控制器(PLC)對液位進行監(jiān)控的一種方法,其電路結(jié)構(gòu)簡單,投資少(可利用原有設(shè)施改造),監(jiān)控系統(tǒng)不僅自動化程度高,還具有在線修改功能,靈活性強,適用于多段液位監(jiān)控場合。
