  AD-MV 554 GT

产品介绍 4通道变送器AD-MV 554 GT是一款可编程的测量设备，用于测量电阻和毫伏信号。由于集成了功能块和自由线性化曲线，AD-MV 554 GT可以通用使用，主要用于温度传感器的温度测量。通过Modbus RTU协议，可以通过适当的寄存器访问测量值。可以使用前面板上可访问的地址开关设置设备地址，范围从1到99。所有参数都通过RS485接口使用PC配置软件"AD-Studio"进行设置。接口参数也可以设置，以便将设备插入现有的总线系统中。工作电压由绿色发光二极管指示。数据通信由黄色发光二极管表示。检测到超出定义的测量范围的无效测量信号时，绿色LED会闪烁。 产品参数
