描述

IC755CSS12CDB

在工业控制中，某些输入量(如压力、温度、流量、转速等)是连续变化的模拟量，某些执行机构(如伺服电动机、调节阀、记录仪等)要求PLC输出模拟信号，而PLC的CPU只能处理数字量。模拟量首先被传感器和变送器转换为标准的电流或电压，如4～20mA，1~5V，0~10V，PLC用A/D转换器将它们转换成数字量。这些数字量可能是二进制的，也可能是十进制的，带正负号的电流或电压在A/D转换后一般用二进制补码表示。

传感器带模拟量输出，模拟量输入，（模块的意思是把你的电压或电流值转换成数字量，然后通过斜率表格就能计算出你当前的温度或压力。）

如果你要求读取温度值或压力值时，那你的传感器必须带模拟量输出和模拟量输出。这样的话你买个模拟模块，把模拟模块跟PLC进行连接，传感器的模拟量输出和输入跟模块进行连接（当然模块上有接线图这你不必担心）。当通上电以后，模块自动检测传感器当前的值然后把它转换成数字量，你根据斜率表计算出它的斜率公式，这样你就能知道它当前的温度值或压力值了。

D/A转换器将PLC的数字输出量转换为模拟电压或电流，再去控制执行机构。模拟量I/O模块的主要任务就是完成A/D转换(模拟量输入)和D/A转换(模拟量输出)。

例如在炉温控制系统中，炉温用热电偶检测，温度变送器将热电偶提供的几十毫伏的电压信号转换为标准电流(如4～20mA)或标准电压(如l～5V)信号后送给模拟量输入模块，经A/D转换后得到与温度成比例的数字量，CPU将它与温度设定值比较，并按某种控制规律(如PID)对二者的差值进行运算，将运算结果(数字量)送给模拟量输出模块，经D/A转换后变为电流信号或电压信号，用来调节控制天然气的电动调节阀的开度，实现对温度的闭环控制。

有的PLC有温度检测模块，温度传感器(热电偶或热电阻)与它们直接相连，省去了温度变送器。

大中型PLC可以配置成百上千个模拟量通道；它们的D/A,A/D转换器一般是12位的。模拟量I/O模块的输入、输出信号可以是电压，也可以是电流；可以是单极性的，如0~5V，0~10V，1~5V，4~20ms,也可以是双极性的，如+50mV，±5V，±10V和±20mA，模块一般可以输入多种量程的电流或电压。

A/D,D/A转换器的二进制位数反映了它们的分辨率，位数越多，分辨率越高，例如8位A/D转换器的分辨率为2-8=0.38％；模拟量输入/输出模块的另一个重要指标是转换时间。
