PLC模块是构成可编程逻辑控制器（Programmable Logic Controller, PLC）系统的核心硬件单元，用于实现工业自动化中的逻辑控制、数据采集与设备驱动等功能。它通常以“模块化”形式存在，可根据控制需求灵活配置和扩展，广泛应用于汽车制造、能源化工、机械加工等工业场景。
核心组成与功能PLC系统由多个功能模块协同工作，主要包含以下几类：
CPU模块
作为PLC的“大脑”，负责执行用户程序、处理输入信号并生成输出控制指令。其性能直接影响系统的运算速度与响应实时性。
输入/输出（I/O）模块
是PLC与外部设备的接口桥梁：
数字量输入（DI）/输出（DO）模块：处理开关信号，如按钮、继电器状态。
模拟量输入（AI）/输出（AO）模块：处理连续信号，如温度、压力传感器数据（4-20mA或0-10V）。
特殊I/O模块：如热电偶、高速计数等专用模块。
电源模块
为整个PLC系统提供稳定的工作电源，通常将交流电转换为直流电（如24VDC），部分还为传感器供电。
通信模块
支持Modbus、PROFINET、EtherNet/IP等工业通信协议，实现PLC与上位机、HMI、伺服系统或其他PLC之间的数据交互。
功能扩展模块
如温度控制模块（如三菱Q64TCTT）、运动控制模块等，满足特定工艺需求。
