PLC模塊是構(gòu)成可編程邏輯控制器（Programmable Logic Controller, PLC）系統(tǒng)的核心硬件單元，用于實現(xiàn)工業(yè)自動化中的邏輯控制、數(shù)據(jù)采集與設備驅(qū)動等功能?。它通常以“模塊化”形式存在，可根據(jù)控制需求靈活配置和擴展，廣泛應用于汽車制造、能源化工、機械加工等工業(yè)場景。

PLC系統(tǒng)由多個功能模塊協(xié)同工作，主要包含以下幾類：

?CPU模塊?
作為PLC的“大腦”，負責執(zhí)行用戶程序、處理輸入信號并生成輸出控制指令。其性能直接影響系統(tǒng)的運算速度與響應實時性。

?輸入/輸出（I/O）模塊?
是PLC與外部設備的接口橋梁：

?數(shù)字量輸入（DI）/輸出（DO）模塊?：處理開關信號，如按鈕、繼電器狀態(tài)。

?模擬量輸入（AI）/輸出（AO）模塊?：處理連續(xù)信號，如溫度、壓力傳感器數(shù)據(jù)（4-20mA或0-10V）。

特殊I/O模塊：如熱電偶、高速計數(shù)等專用模塊。

?電源模塊?
為整個PLC系統(tǒng)提供穩(wěn)定的工作電源，通常將交流電轉(zhuǎn)換為直流電（如24VDC），部分還為傳感器供電。

?通信模塊?
支持Modbus、PROFINET、EtherNet/IP等工業(yè)通信協(xié)議，實現(xiàn)PLC與上位機、HMI、伺服系統(tǒng)或其他PLC之間的數(shù)據(jù)交互。

?功能擴展模塊?
如溫度控制模塊（如三菱Q64TCTT）、運動控制模塊等，滿足特定工藝需求。
