iso685-D-B - Isolationsüberwachungsgerät für AC/DC

The ISOMETER iso685 is an insulation monitoring device for IT systems in accordance with IEC 61557-8. It can be used universally in AC, 3(N)AC, AC/DC and DC systems. In AC systems, extensive DC-fed system components may also be present (e.g. power converters, inverters, controlled drives).

Device variants:

iso685-D:

The iso685-D device version has a high-resolution, graphic LC display and controls for direct operation of the device functions

Operating elements for direct operation of the device functions.

iso685-S:

The iso685-S device version has no display and no operating unit. It can be used in

Used in combination with FP200 and is operated indirectly via this.

Parameterization can also be carried out via the web browser or a COM465.

Option "W"

The device variants are optionally available with the W option for extreme climatic and mechanical

mechanical stresses.

Main features:

 Predefined measurement profiles

 Reliable measurement of insulation resistance, voltage, capacitance and frequency

Features and functions:

 ISOMETER for IT AC voltage systems with galvanically connected rectifiers or converters and for IT DC voltage systems (IT = unearthed systems).

 The operating range of the rated mains voltage Un can be extended via coupling devices.

 Automatic adaptation to the existing system leakage capacitance.

 Combination of AMPPlus and other profile-dependent measuring methods

 Two separately adjustable response value ranges of 1 kΩ...10 MΩ for alarm 1 and for alarm 2

 High-resolution graphic LC display for easy reading and recording of the device status

 Connection monitoring (monitoring of the test leads)

 Automatic device self-test

 Graphical representation of the insulation curve over time (isoGraph)

 History memory with real-time clock (3-day buffer) 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 isolated) analogous to the measured insulation value of the system
