  • Desti ned for data transmission through radio way in the non-licensed band: 869.4 - 869.65 MHz.
  • Co-operates with RS-485 and RS-232 interfaces.
  • Output power: 500 mW.
  • Finds applicati on in telemetering systems in which there is no technical possibiliti es to conduct wires for device connecti ons in the shape of a wire network.
  • Operati ng range of the MR03 module: 2 km, on average (depending on the terrain confi gurati on and applied antenna).
  • Available working modes allow individual communicati on of MR03 module pairs (“point-to-point” mode) and broadcast communicati on (“point-to-many points” mode). power Transmitter Example of application KD7MR03MR03SM1 KD7 2x input 4-20 mA 2x output 4-20 mA Zasilanie RS 485 RS 232 RS 485Supply
