Wireless Functional Safety

The radio controlled safety system UH 6900 offers high availability, long transmission range (> 800 m), and maximum safety up to cat. 4 / PL e or SIL 3


Radio controlled safety module UH 6900


The safety approved, bidirectional SAFEMASTER W series radio controlled safety module UH 6900, is for the transmission of safety inputs such as E-stop and conventional control functions and offers great flexibility for the protection of hazardous areas. By implementing the latest radio controlled technologies, a high degree of availability, a wide range, and safety is achieved. Two safety zones can easily be connected wirelessly over a considerable distance.


The main application areas include applications covering large areas and mobile applications such as fully automated conveyor systems and driverless transport systems. Simple and inexpensive retrofitting of existing safety systems can also be achieved wirelessly with this system.


The device allows connection of up to 3 two-channel safety transmitters (E-stop, LC, safety gate, two-hand, etc.), simple configuration, and comprehensive sampling and diagnostic options.


With the radio controlled safety system, you will have an automated safety solution that can be integrated wirelessly into various applications. The option to select between three operating modes (complete protected mode, cross mode, protected mode with connectable ratio control) allows the device to be quickly and reliably adapted to your individual application.
