ISOMETER® iso685-…-B

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

The ISOMETER® is a ground-fault monitoring device in accordance with IEC 61557-8 for IT systems. The device 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, variable-speed drives).

Device variants
iso685-D-B: This device variant ISOMETER® iso685-D-B 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-B: This device variant ISOMETER® iso685-S-B 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-B and iso685W-S-B).

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 AMP^Plus 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
