FSK Wireless Radio Module RS485 Half Duplex UHF Digital Data Transmitter


Features:


  1. 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.
  2. High-speed, stable, compatible and reliable
  3. 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)
  4. 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.
  5. Support MODBUS,PPI and other communication protocols to support wireless download PLC program
