  • Transport ferroviaire
  • Utilisation universelle

L´ISOMETER® isoRW685W-D est un contrôleur permanent d´isolement pour réseaux IT destiné à des applications dans le domaine ferroviaire qui a été testé selon la norme IEC 61557-8 et spécialement selon DIN EN 50155. Utilisable dans des réseaux AC, 3(N)AC, AC/DC et DC. Les réseaux AC peuvent comprendre des parties d´installation alimentées en courant continu (par exemple convertisseurs, variateurs, entraînements à vitesse variable).

  • ISOMETER® for IT AC systems with galvanically connected rectifiers or inverters and for IT DC systems (IT = unearthed systems).
  • Nominal system voltage Un expandable via coupling devices
  • Automatic adaptation to the existing system leakage capacitance.
  • Combination of AMPPlus and other profilespecific measurement methods.
  • Two separately adjustable response value ranges of 1 kΩ…10 MΩ for alarm 1 and alarm 2
  • High-resolution graphic LC display for excellent readability and recording of the device status.
  • Connection monitoring (monitoring of the measuring lines).
  • Automatic device self test.
  • Graphical representation of the insulation resistance over time (isoGraph)
  • History memory with real-time clock (buffer for three days) for storing 1023 alarm messages with date and time.
  • Current and voltage output 0(4)…20 mA, 0…400 μA, 0…10 V, 2…10 V (galvanically separated) which is analogous to the measured insulation value of the system.
  • Freely programmable digital inputs and outputs.
  • Remote setting via the Internet or Intranet (Webserver/Option: COMTRAXX® Gateway).
  • Worldwide remote diagnosis via Internet.
  • RS-485/BS (Bender sensor bus) for communication with other Bender devices
  • BCOM, Modbus TCP and web server
  • AC, DC or AC/DC main circuits
  • AC/DC main circuits with directly connected DC components, such as rectifiers, converters, variable-speed drives
  • UPS systems, battery systems
