Wireless data transmission of serial interfaces via Bluetooth (transmission up to 150 meters)

The new PSI Line Bluetooth interface converters make complex data connections with mobile devices using flexible conduits, slip rings or other cable solutions a thing of the past.

The universal PSI Line interface converters make wireless transmission of the serial interfaces RS-232, RS-422, RS-485 2-wire and USB possible.


Time-consuming maintenance involving high costs is therefore unnecessary. This simple cable substitute with the Bluetooth wireless technology offers you a fast, flexible, and inexpensive solution for your programming or diagnostics connection to a machine, controller, or when connecting a new device in an existing bus system (e.g. Modbus, Profibus, etc.).
Wireless interface converters for RS-232, RS-422, RS-485 and USB.



Easy cable replacement up to 150 meters

PSI Line Bluetooth adapters are especially preferred for temporary maintenance and diagnostic connections. Their compact design and integrated antenna are quick and easy additions to the PSI Line Bluetooth converters.

The PSI Line Bluetooth interface converters prove themselves again every day as universal "easy cable replacements".

Extra data security is provided by the password protection option for the devices, or, on the other hand, by making the devices invisible for other devices after the connection has been established.

Bluetooth therefore proves itself as an industrial cable replacement for point-to-point connections and also supports point-to-multipoint connections with up to seven devices.


Your user advantages include:

  • Fast startup
  • Fast setting up of the connection
  • High transmission reliability
  • High levels of flexibility
  • Short installation time
  • Low procurement costs
  • No ongoing costs thanks to the license-free ISM band
  • Suitable for industrial applications at medium ranges
