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
Features:
- 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
