ISOMETER® iso685-…-P

ISOMETER® iso685-…-P

  • Predefined measurement profiles
  • Reliable measurement of insulation resistance, voltage, capacitance and frequency
  • Integrated web server
  • Modbus TCP/RTU
  • History memory

The ISOMETER® is an insulation monitoring device for IT systems in accordance with IEC 61557-8 and IEC 61557-9. It is universally applicable in AC, 3(N)AC, AC/DC and DC systems. AC systems may include extensive DC-supplied loads (such as rectifiers, inverters, variablespeed drives).

In combination with the insulation fault locators of the EDS44x series or the appropriate measuring current transformers, an insulation fault location system can be set up with the iso685-…-P.


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.
