PLC體積小，重量輕，易于安裝。 PLC的輸入輸出系統(tǒng)可以直觀地反映現(xiàn)場信號的變化狀態(tài)，可以通過方式直觀地反映控制系統(tǒng)的運(yùn)行狀態(tài)，如內(nèi)部工作狀態(tài)，通信狀態(tài)，I / O點(diǎn)狀態(tài)，異常狀態(tài)，和電源狀態(tài)。有一些引人注目的說明，這對操作和維護(hù)人員監(jiān)控系統(tǒng)非常有利。1747-L542羅克韋爾PLC
供應(yīng)可編程控制器的輸入信號類型可以是開關(guān)量、模擬量和數(shù)字量。一般來說，輸入單元由兩部分組成：一部分是與被控制設(shè)備相連的接口電路，另一部分是輸入圖像寄存器。
輸入單元接收來自用戶設(shè)備的控制信號，如限制開關(guān)、操作按鈕、選擇開關(guān)、跳轉(zhuǎn)開關(guān)和其他傳感器。通過接口電路，這些信號被轉(zhuǎn)換成處理器能夠識(shí)別和處理的信號，與輸入的圖像寄存器共存。運(yùn)行時(shí)cpu從輸入圖像寄存器中讀取輸入信息并對其進(jìn)行處理，將處理結(jié)果存儲(chǔ)在輸出圖像寄存器中。
為了防止干擾信號和高壓信號進(jìn)入PLC，影響其可靠性或造成設(shè)備損壞，現(xiàn)場輸入接口電路一般采用光電耦合電路隔離。光電耦合電路的關(guān)鍵器件是光耦合器，通常由發(fā)光二管和光電晶體管組成。1747-L542羅克韋爾PLC通常PLC輸入類型可以是DC（DC24V），AC和AC和DC。輸入電路的電源由外部提供。有些也可以由PLC內(nèi)部提供。對于DC輸入，根據(jù)場輸入接口電路的形式，它分為兩種類型：源輸入和宿輸入。絕大多數(shù)歐洲和美國的PLC使用泄漏輸入，而絕大多數(shù)亞洲的PLC使用源輸入。
