1756-IN16/ABPLC模塊

為實現(xiàn)液位的手動/自動控制，需要輸入口12點，輸出口8點，選用C20P 20點I/O單元的PLC，輸入光電隔離，輸出繼電器隔離，負(fù)載能力強(qiáng)；液位檢測采用干簧管傳感器，手動/自動轉(zhuǎn)換、運(yùn)行/試驗轉(zhuǎn)換和液位設(shè)定采用雙位旋鈕，手動啟泵、停泵和確認(rèn)、試驗采用常開按鈕；輸出選用電子音響報警器和24V直流指示燈、繼電器。參見圖一系統(tǒng)硬件配置圖。

為節(jié)省輸入口數(shù)量，節(jié)省投資，本系統(tǒng)運(yùn)行/試驗功能的轉(zhuǎn)換采用了對I/O模塊接線的優(yōu)化，使PLC輸入模塊中1個輸入節(jié)點起到2個輸入節(jié)點的作用，完成PLC工作在兩種方式下的I/O功能。參見圖二I/O模塊接線的優(yōu)化。
