Radioline wireless system

Radioline wireless module  

Radioline is the wireless system for large systems

Radioline is the wireless system for large systems. The wireless system can be used to wirelessly network multiple controllers or serial I/O devices quickly and easily via RS-232 or RS-485 serial interfaces. Data transmission is transparent, which means that any protocols, such as Modbus or PROFIBUS, can be forwarded.

  • High degree of reliability, thanks to Trusted Wireless technology
  • Supported frequency bands: 868 MHz / 900 MHz / 2.4 GHz
  • Range of up to 32 kilometers, thanks to adjustable data rate
  • Flexible network configuration: Radioline supports both point-to-point connections and complex mesh networks with up to 250 nodes
  • Save on devices: transmit I/O signals and serial data using a single device, thanks to the integrated RS-232/RS-485 interface
  • Can be extended with up to 32 I/O modules: thanks to DIN rail connector and hot-swap capability

Application example for the replacement of PROFIBUS cables with Radioline

Wireless transmission of serial data between two sedimentation tanks  

Replacement for PROFIBUS cables

Slip rings can present a problem in data communication, especially for rotating applications. Wireless systems from Phoenix Contact allow you to integrate moving or hard-to-reach automation devices into your PROFIBUS automation network easily, reliably and cost-effectively. Achieve optimum water quality, thanks to reliable monitoring of the secondary sedimentation process.

  • RAD-2400-IFS wireless module as a replacement for PROFIBUS cables
  • PROFIBUS data rate of up to 93.75 kbps
  • Range of up to 3 km
  • Up to 14 nodes in a star network
