PLC系统中使用的模拟量有两种，一种是模拟电压，一种是模拟电流，模拟电压最常见，用的也最多。
模拟电压一般是0~10V，并联相等，长距离传输时容易受干扰，一般用在OEM设备中。
模拟电流一般是4~20mA，串联相等，抗干扰能力强，dcs系统中一般都使用模拟电流。
我们先要用传感器测量我们所需要的参数，通过变送器将此参数变换成0~10V或者4~20mA，现在很多传感器都是自带变送器的，直接就输出模拟量，建议大家在项目中选用此种类型的传感器图二某压力传感器手册如图二所示，是某压力开关的选型手册，红色圆圈部分是它的量程0~250公斤，再看黄色荧光笔部分，此型号的传感器是模拟电流输出，也就是此款传感器将0~250公斤的压力线性转换成了4~20mA的电流，当我们检测到12mA的电流时，就表示压力是125公斤，依此类推。
视频信号传输一般采用直接调制技术、以基带频率（约8MHz带宽）的形式，最常用的传输介质是同轴电缆。
同轴电缆是专门设计用来传输视频信号的，其频率损失、图像失真、图像衰减的幅度都比较小，能很好的完成传送视频信号的任务。

其中常用的七脚管有6A6K6J6J6G6Z4等；常用的九脚管有6P6N6P16U6E6E2，由于这两类管子都属于玻璃外壳的小型管子，也称为指形管或花生管，而把它们的管脚称为小七脚、小九脚。
这些管子的管脚朝向自己，有两只管脚之间的距离较大，我们称这段较大距离为缺口，把缺口左边第一只管脚数为第一脚，按顺时针方向依次为第第..。
如上图典型的双三脚管管脚图。
八脚管，如6P6P、6J8P、5Z3P等，这些管子的管脚之间的距离是相等的，为了防止插错又设了一个中心管钥其定位作用，管钥左边第一个管脚为第一脚，顺时针方向依次为第二脚....如上图所示。
当数据在高速率传输的情况下，线路就呈现传输线效应，此时负载的特性阻抗必须与输出相匹配，否则，就会导致信号回波反射、系统不能正常工作。
某些情况下，可以通过在末端并联匹配电阻等方法来实现阻抗匹配，但长远来说，一旦该电阻因某种原因改变而会重新发生故障，此种方法还会带来增大系统功率消耗的弊端。
