I/0模塊是CPU與現(xiàn)場I/0裝置或別的外部設(shè)置裝備擺設(shè)之間的毗連部件。PLC提供了種種操縱電平與驅(qū)動本領(lǐng)的I/0模塊和種種用途的I/0組件供用戶選用。如輸入/輸出電平轉(zhuǎn)換、電氣斷絕、串/并行轉(zhuǎn)換數(shù)據(jù)、誤碼較驗、A/D或D/A轉(zhuǎn)換以及別的功效模塊等。I/0模塊將外界輸入信號釀成CPU能擔當?shù)男盘枺驅(qū)PU的輸出信號釀成必要的控制信號去驅(qū)動控制工具（包羅開關(guān)量和模仿量），以確保整個別系正常事情。
輸入的開關(guān)量信號接在IN端和0V端之間，PLC內(nèi)部提供24V電源，輸入信號通過光電斷絕，通過R/C濾波進入CPU控制板，CPU發(fā)出輸出信號至輸出端。PLC輸出有三種型式：繼電器方法、晶體管方法和晶閘管方法。
（5）編程器
編程器是用于用戶步伐的體例、編輯、調(diào)試查抄和監(jiān)督等。還可以通過其鍵盤去挪用和表現(xiàn)PLC的一些內(nèi)部狀態(tài)和體系參數(shù)。它通過通訊端口與CPU接洽，完P(guān)LC機對話毗連。編程器上有供編程用的種種功效鍵和表現(xiàn)燈以及編程、監(jiān)控轉(zhuǎn)換開關(guān)。編程器的鍵盤接納梯形圖語言鍵符式下令語言助記符，也可以接納軟件指定的功效鍵符，通過屏幕對話方法舉行編程。
編程器分為淺易型和智能型兩類。前者只能連機編程，爾后者既可連機編程又可脫機編程。同時前者輸入梯形圖的語言鍵符，后者可以直接輸入梯形圖。憑據(jù)差別檔次的PLC產(chǎn)品選配相應(yīng)的編程器。
隨著科學(xué)技能的生長，PLC在產(chǎn)業(yè)控制中的應(yīng)用越來越廣泛。PLC控制體系的可靠性直接影響到產(chǎn)業(yè)企業(yè)的寧靜生產(chǎn)和經(jīng)濟運行，體系的抗滋擾本領(lǐng)是干系到整個別系可靠運行的關(guān)鍵。主動化體系中所利用的種種范例PLC，有的是會合安置在控制室，有的是安置在生產(chǎn)現(xiàn)場和種種電機設(shè)置裝備擺設(shè)上，
