400-470MHz Reliabe Wireless Data Module FSK Modulation Data Link

Main application:

  • Oil and gas production, pipeline monitoring
  • Gas distribution, heating network monitoring
  • Water wells, water and wastewater monitoring system
  • GPS positioning systems, mobile data transmission
  • Earthquakes, meteorology, environmental protection and urban lighting control
  • Railway, transport, security, data transfer control system
  • Metallurgy, chemical and industrial automation and process control
  • Wind, solar energy monitoring and control system
  • Lights, landscape lights remote control


  • High-speed, stable, compatible and reliable
  • Wide operating voltage: DC9V~36V
  • Integrated with bust-boost converter ,when input DC 9v~36v voltage,it can work properly without affect the function and performance of radio. Its power supply system support DC9-15V, DC24V and other occasions.
  • Transfer rate support the range of 1200~9600bps
  • User can modify the transfer rate by computer install the software to achieve optimal communication effect.
  • Variety of communication interfaces coexist:
  • Radio provide RS-485, RS-232 serial port, users do not need to switch. (user can only use only one interface at a time)
  • Data delay is less than 10ms, you can replace the RS-485 cable systems in a variety of occasions, the upper layer software without changes.
  • Support MODBUS,PPI and other communication protocols to support wireless download PLC program
  • RF power and working frequency can be setup by PC
