Multichannel transmitter RMD680 has been designed for applications where lots of inputs have to be measured and transferred economically either to PC or PLC. Transmitter has 16 input channels, which can be programmed individually for different sensors. Measurement rate is 12 channels per second. Measurements can be read either by serial interface RS-485 using Modbus RTU or Nokeval SCL protocol or with one analog output.
