RMD680 8/16通道通用输入发射器和多路与串行输出RS-48520 ma, -20 . .+ 20 ma 0 . .10 v, -10 . .+10V•mV输入范围:-100..•RTD传感器:Pt100, Pt1000, Ni, Cu, KTY83•电阻输入范围:0..1个模拟输出0/4..20 mA或0..•2个报警继电器，带有常见报警•前面板显示•前面板按键或串行接口RS-485编程•Modbus RTU和Nokeval SCL串行协议•电源24 VDC，多通道变送器RMD680已被设计用于许多输入必须被测量和转移到PC或PLC经济的应用。变送器有16个输入通道，可针对不同的传感器分别编程。测量速率为每秒12通道。测量数据可以通过使用Modbus RTU或Nokeval SCL协议的串行接口RS-485读取，也可以通过一个模拟输出。多达32个设备可以连接到同一串行总线没有中继器。从一台设备读取所有通道需要30毫秒，因此可以在不到一秒的时间内读取512个通道。 When analog output is used, output channel is selected with a 4-bit digital input. Transmitter has also 4-bit digital input for enabling its analog output thus total channel count can be increased to a maximum of 256 channels by connecting mA outputs of several devices in parallel. This way all channels from one device can be read in less than one second.
