iso685W-S-P Isolationsüberwachungsgerät
Product description
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).
iso685-S:
The iso685-S device version has no display and no operating unit. It can only be used in
Combination with FP200 and is operated indirectly via this.
Parameterization can 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 available.
Main features:
- Predefined measurement profiles
- Reliable measurement of insulation resistance, voltage, capacitance and frequency
- Integrated web server
- Modbus TCP/RTU
- Insulation fault location
