Wireless PROFIBUS 869 MHz – DATAEAGLE 3333A

Long-range wireless PROFIBUS transmission

Wireless PROFIBUS at 869 MHz

DATAEAGLE 3333A transmits PROFIBUS DP communication wirelessly over long distances. It is suitable for large industrial sites, outdoor technologies, cranes, water-management applications and locations where installing or regularly maintaining a data cable would be too demanding.

  • 869 MHz radio band
  • Range up to 300 m indoors
  • Outdoor range approximately 1–3 km
  • Compact IP20 or X-TREME IP65
  • Plug & Play PROFIBUS retrofit

Schildknecht DATAEAGLE 3333A for wireless PROFIBUS at 869 MHz
1 Select the housing version Compact IP20 for the control cabinet or X-TREME IP65 for direct installation in the plant.
2 Select the unit roles At least one DATAEAGLE 3333A transmitter and one receiver are required.
3 Design antennas and power supply Consider distance, obstacles and continuous power for all units.
How do you select the correct DATAEAGLE 3333A system for 869 MHz?

Choose the version according to the installation location

Control cabinet – IP20

DATAEAGLE 3333A Compact

A slim version for DIN-rail mounting inside a control cabinet. PROFIBUS is connected through a standard 9-pin D-sub connector and the antenna through an SMA connector.

  • 11142: Compact transmitter,
  • 11143: Compact receiver,
  • 24 V DC power supply through a terminal block,
  • IP20 protection and DIN-rail mounting,
  • module width only 22.5 mm.
Direct installation – IP65

DATAEAGLE 3333A X-TREME

A robust metal version for installation directly on the machine, supporting structure or in an outdoor industrial environment. Power and PROFIBUS are connected through industrial M12 connectors.

  • 11370: X-TREME transmitter,
  • 11371: X-TREME receiver,
  • 24 V DC power through an A-coded M12 connector,
  • PROFIBUS through B-coded M12 connectors,
  • IP65 protection for demanding environments.
Transmitter – radio master

The main radio unit in the system. It is usually installed on the fixed part of the equipment or near the main section of the PROFIBUS network.

Receiver – radio slave

A remote radio unit installed on a moving or isolated section of the equipment. The terms transmitter and receiver describe the roles within the radio system.

Point-to-point

One transmitter–receiver pair replaces one long or mechanically stressed cable connection. This is the simplest and most transparent configuration.

Multipoint

One transmitter communicates with several remote sections of the equipment. All connected units must be powered correctly and the design must respect the required response time of the complete network.

Main DATAEAGLE 3333A features

869 MHz radio frequency
Frequency version intended for the European Union
Transparent PROFIBUS DP transmission
PROFIBUS speed up to 1.5 Mbit/s
Transmit power up to 500 mW EIRP
Industrial 24 V DC power supply
External antenna through an SMA connector
Compact IP20 and X-TREME IP65 versions
Operating temperature approximately −20 to +60 °C
up to 300 m indicative range inside an industrial hall
approx. 1 km commonly stated outdoor system range
up to 3 km with suitable antennas and good conditions

Important: all units must remain powered

For fast and stable response in a multipoint system, all DATAEAGLE units must remain continuously powered.

When a machine or process section is switched off regularly, we recommend placing it in a separate wireless system. This prevents one powered-down section from affecting communication with the other units.

Do you also need to transmit PROFIsafe?
DATAEAGLE 3333A at 869 MHz is not intended for PROFIsafe transmission. For safety communication, use a suitable DATAEAGLE 373x version at 2.4 GHz and verify the safety timing of the application in advance. View the 2.4 GHz solution

Where is DATAEAGLE 3333A most often used?

Wastewater treatment and water management
Large production and logistics sites
Overhead and gantry cranes
Outdoor conveyor systems
Warehouse and material-handling systems
Lifts, cableways and lifting equipment
Tunnelling and mining machines
Steelworks, cement plants and heavy industry
Replacement of a long or repeatedly damaged cable
The antenna is not automatically included with the unit:
Each transmitter and receiver requires its own antenna. An omnidirectional or directional antenna may be suitable depending on distance, equipment movement, line of sight, cabinet positions and surrounding obstacles. Antenna-cable length and correct antenna polarisation are also important.
How should you prepare an enquiry?
Send us a network diagram, the number of remote sections, the PROFIBUS transmission speed, required distance, information about equipment movement, photographs of the environment and the power-supply arrangement for each section. We will recommend the number of transmitters and receivers, Compact or X-TREME versions, antennas and accessories.

PROFIBUS: 3 Sins and 10 Tips

PROFIBUS: 3 Sins and 10 Tips

The PROFIBUS industrial bus is highly tolerant and will forgive many faults. But if a critical fault occurs—or several small ones accumulate—you will definitely notice. That’s why this aging industrial network deserves attention. Even if faults on your network are still rare, they will gradually accumulate. What do our technicians recommend? What are their 10 tips for maintaining PROFIBUS?
