The functions of the PLC can be divided into several functional groups.Many PLC manufacturers integrate these functions into separate modules,and the capabilities of each module vary depending on the specific application.Many modules have multiple functions and can interface with a variety of sensors.However,in most cases dedicated modules or expansion modules are designed for special applications such as resistance temperature detectors(RTDs),sensors or thermocouple sensors

PLC的功能可划分成几个功能组。许多PLC厂商将这些功能集成为独立模块，每个模块所具备的功能随具体应用而有所不同。很多模块具有多种功能，可与多种传感器接口连接。然而，多数情况下会针对特殊应用设计专用模块或扩展模块，例如：电阻温度检测器（RTD）、传感器或热电偶传感器
