来源：未知 日期：2018/03/16 浏览量：次
对于大多数的控制系统而言，常常需要将输入信号转换为系统可接受的信号模式。那么信号调节器的功能就是将各种现场信号，例如热电偶，热电阻转换为多种标准的仪表信号(1…5V, 4…20 mA, 等.)。
信号调节器对于信号的精确传输、信号的隔离以及防止信号干扰等方面起到很大的作用。
在现场电路和控制电路之间。该设备转换RTD输入。信号或热电偶输入场侧信号为0/4毫安…20ma信号对控制方。可移动终端块KC-CJC-** 是可用的内部热电偶时的热电偶LD结补偿渴望的.一个故障由一个LED和用户配置的故障指示。指示输出。如果设备是vi操作的电源轨，另外A可用的集体错误信息。该装置是由使用的PACTware轻松配置组态软件。
