ISOMETER® iso685-…-B
- Predefined measurement profiles
- Reliable measurement of insulation resistance, voltage, capacitance and frequency
- Integrated web server
- Modbus TCP/RTU
- Can be used in coupled IT systems
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: 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.
Option "W": The ISOMETER®s with and without integrated display are available for extreme climatic and mechanical conditions.
