AS-S908-110 稳压器

PLC的对外功能，主要是通过各种I/O接口模块与外界联系的，按I/O点数确定模块规格及数量，I/O模块可多可少，但其大数受所能管理的基本配置的能力，即受大的底板或机架槽数限制。I/O模块集成了PLC的I/O电路，其输入暂存器反映输入信号状态，输出点反映输出锁存器状态。

三、电源模块：

有些PLC中的电源，是与模块合二为一的，有些是分开的，其主要用途是为PLC各模块的集成电路提供工作电源。同时，有的还为输入电路提供24V的工作电源。电源以其输入类型有：交流电源，加的为交流220VAC或110VAC，直流电源，加的为直流电压，常用的为24V。

四、底板或机架：

大多数模块式PLC使用底板或机架，其作用是：电气上，实现各模块间的联系，使能访问底板上的所有模块，机械上，实现各模块间的连接，使各模块构成一个整体。

五、PLC的外部设备

外部设备是PLC系统不可分割的一部分，它有四大类

1.编程设备：有简易编程器和智能图形编程器，用于编程、对系统作一些设定、PLC及PLC所控制的系统的工作状况。编程器是PLC开发应用、监测运行、检查维护不可缺少的器件，但它不直接参与现场控制运行。

2.设备：有数据和图形。直接监视数据或通过画面监视数据。
