ISOMETER® iso685-…-B

  • Predefined measurement profiles
  • Reliable measurement of insulation resistance, voltage, capacitance and frequency
  • Integrated web server
  • Modbus TCP/RTU
  • Can be used in coupled IT systems

The ISOMETER® is an insulation monitoring devices in accordance with IEC 61557-8 for IT systems. The devices are universally applicable in AC, 3(N)AC, AC/DC and DC systems. AC systems may include extensive DC-supplied loads (such as rectifiers, inverters, variable-speed drives).

Device variants
iso685-D: This device variant ISOMETER® iso685-D features a high-resolution graphic LC display and operating controls for direct operation of the device functions. It cannot be combined with an FP200.
iso685-S: This device variant ISOMETER® iso685-S features neither a display nor operating controls. It can only be used in combination with the FP200 and it is operated via this front panel.
Option "W": The ISOMETER®s with and without integrated display are available with option „W“ for extreme climatic and mechanical conditions (ISOMETER® iso685W-D and iso685W-S).

Features

  • 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 AMPPlus and other profilespecific measurement methods
  • Two separately adjustable response value ranges of 1 kΩ…10 MΩ
  • 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 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
  • RS-485/BS (Bender sensor bus) for communication with other Bender devices
  • ISOnet: Internal separation of the ISOMETER® from the IT system to be monitored (e.g. if several IT systems are interconnected)
  • BCOM, Modbus TCP/RTU and web server
  • Voltage expandable via coupling devices

Applications

  • 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 switch-mode power supplies
  • coupled IT systems with high leakage capacitances
