1756-OA16I/ABPLC模塊
PLC是繼電器、接觸器、順序控制器以及由中、小規(guī)模的集成電路及其它電氣元件的復(fù)雜控制系統(tǒng)裝置上發(fā)展起來(lái)的一種新型控制器,采用微電腦技術(shù)(大規(guī)模集成電路)取帶了以往靠硬導(dǎo)線布線的邏輯控制器,具有成本低,功耗、體積小,重量輕等特點(diǎn)。
一套完整的PLC主要由6個(gè)模塊構(gòu)成:電源模塊、CPU模塊、熱備模塊(可選)、開(kāi)入/開(kāi)出(I/O)模塊、A/O模塊、通訊模塊。其中電源模塊向PLC提供直流24V工作電源;CPU是微型處理器(PLC的核心部位);熱備模塊是在兩套PLC均為在線方式下互為熱備用,并且可以人為任意切換至工作或備用狀態(tài),提高安全可靠性;開(kāi)入/開(kāi)出(I/O)模塊是指外圍回路向PLC輸入高電平(或低電平)和PLC向外圍回路輸出高電平(或低電平);模數(shù)轉(zhuǎn)換(A/O)模塊是將外圍設(shè)備輸入的電信號(hào)轉(zhuǎn)換成數(shù)字信號(hào),以供PLC進(jìn)行計(jì)算、判斷、比較和傳輸(配置如圖1所示)。
