ISOMETER® iso685-…-B
- Predefined measurement profiles
- Reliable measurement of insulation resistance, voltage, capacitance and frequency
- Integrated web server
- Modbus TCP
- History memory
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-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).
