2071面板表串行通信•串行输入RS-232和RS-485•基于6位处理器的LED显示•输入电流隔离•前面板按键可读取•电源85..240前面板保护IP65面板表2071是设计用于串口通信。它使用简单的Nokeval SCL协议,其中只发送地址、值和校验和。面板表具有串行输入RS-232和RS-485作为标准。串行总线与处理器和电源隔电隔离。在配置模式下,您可以设置通电后显示的地址、波特率和数值类型。在工业环境中,总是建议使用可寻址串行信号RS-485。31个显示器可以连接到一个总线上,通过使用串行数据转换器(721R),可以增加另外31个显示器。公共汽车的最大距离是1公里。串行输入RS-232只接受一个显示器连接到总线,最大距离为15米。 Front panel protection is IP65. The panelmeter series 2000 is very flexible and easy to modify by changing input cards for different kinds of sensors, such as temperature sensors, pulse sensors, serial inputs etc. The modification does not require any calibration. The optional cards are the same for all the instruments in this product family. Each panelmeter type has its own datasheet. Separate field enclosures can be supplied for 1 to 3 panelmeters. The 2071 is also available in the field display series, model 2800-2071.
