DEUTA REDsafe - Safety Unit with SIL Certification

Train Protection with DEUTA REDsafe

With its various integration options, the DEUTA REDsafe is ideally suited for assembly in locomotives and working vehicles. The cassette is mounted as a ‘stand-alone unit‘ in a 19“ rack. It is incorporated as a safety module in the train protection e.g. in the PZB environment.

Driver’s Safety Device (DSD) and further functions

The travel data recorder REDsafe is a closed platform for DSD functions. It corresponds to the requirements of the UIC 641 and other rail standards with additional safety functions such as:

  • DSD
  • Detection of standstill
  • Rollback protection
  • Speed thresholds (e.g. Vmax, Vgrenz)
  • Monitoring of speed signals
  • Safe Speed Transmission – analogue
  • Safe Speed Transmission – via bus system
  • Safe changing of parameters during the drive
  • We are happy to support you with other requirements too. 

The Speed Control Unit: functional safety up to SIL4

The SCU (Speed Control Unit) of the DEUTA REDsafe is devised as a 2 channel structure with independent processors and control relays. In this way, SIL conformity of safety functions up to level 4 is made possible, depending on integration. As required, REDsafe can transmit all occurring status messages to a superordinate system. MVB buses, CAN or Ethernet can be used for this. 

Flexible configurations

The design of the DEUTA REDsafe allows for high flexibility in configuration, parametrisation and in application, e.g. as time-time or distance-distance DSD.

Die REDsafe replaces the ES 122 DSD conforming to operator procedures. Alongside project relevant safety functions, it provides additional service and diagnostic functions, such as status info via ethernet connection.
