ISOMETER® iso685…

ISOMETER® iso685…

  • Voorgedefinieerde meetprofielen
  • Veilige meting van isolatieweerstand, spanning, capaciteit en frequentie
  • Geïntegreerde webserver
  • Modbus TCP/RTU
  • Historiegeheugen

De ISOMETER® is een isolatiebewakingsapparaat volgens IEC 61557-8 voor IT-systemen. Dit product is universeel inzetbaar in AC-, 3(N)AC-, AC/DC- en DC-systemen. In AC-systemen kunnen ook omvangrijke installatieonderdelen met gelijkstroomvoeding aanwezig zijn (bijv. statische omvormers, gelijkrichters, geregelde aandrijvingen).

Device variants
iso685-D: The device variant iso685-D features a high-resolution graphic LC display and operating controls for direct operation of the device functions.
iso685-S: The device variant iso685-S is operated via the detached operating unit FP200.
Option "W": The ISOMETER®s with and without integrated display are available for extreme climatic and mechanical conditions.


  • ISOMETER® for IT AC systems with galvanically connected rectifiers or inverters and for IT DC systems (IT = unearthed systems)
  • Automatic adaptation to the existing system leakage capacitance
  • Combination of AMPPlusand other profilespecific measurement methods
  • Two separately adjustable response value ranges of 1 kΩ…10 MΩ
  • High-resolution graphical LC display
  • 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 or 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 the Internet (made available by Bender Service only)
  • RS-485/BS (Bender sensor bus) for data exchange with other Bender devices 
  • BCOM, Modbus TCP/RTU and web server 
  • Voltage expandable via coupling devices


  • 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
  • Heaters with phase control
  • Systems including switched-mode power supplies
  • IT systems with high leakage capacitances
