Product Description

The Bender ISOMETER® iso685-D is a high-end, intelligent Insulation Monitoring Device (IMD) designed for unearthed (IT) systems. It complies with IEC 61557-8 standards and is engineered to provide precise monitoring of insulation resistance in complex power systems, including those with high leakage capacitance or power electronics.

The iso685-D variant features an integrated high-resolution graphic LC display and local operating controls for direct configuration and monitoring. It is designed for universal application in AC, 3(N)AC, AC/DC, and DC systems.

Product Parameters

• System Compatibility: AC, 3AC, AC/DC, and DC IT systems (unearthed).
• Nominal System Voltage (U_n):
  • AC: 0…690 V
  • DC: 0…1000 V
  • (Can be extended to higher voltages using optional coupling devices).
• Measurement Range: 1 kΩ to 10 MΩ (two separately adjustable response values).
• Measurement Technology: Uses the patented AMPPlus method, which is highly effective for systems with rectifiers, inverters, and variable-speed drives.
• Interfaces/Outputs:
  • Integrated Web Server (for remote monitoring via Ethernet).
  • Modbus TCP/RTU.
  • Analog outputs (0/4–20 mA, 0–10 V, etc.).
  • Programmable digital inputs/outputs.
• Display: High-resolution 127×127 pixel graphic LC display.
• History Memory: Stores up to 1023 alarm messages with date and time stamps.

Product Advantages

• Versatility: Automatically adapts to the system’s leakage capacitance, making it ideal for systems with large cable lengths or EMI filters.
• Advanced Diagnostics: Features the isoGraph function, which displays insulation resistance trends over time, allowing for predictive maintenance before a critical fault occurs.
• Easy Commissioning: Comes with predefined measurement profiles for various applications (e.g., inverters, generators, control circuits), simplifying setup.
• Remote Accessibility: The built-in web server allows users to check status and change settings from any PC or mobile device on the network.
• Robustness: Self-monitoring and automatic device self-tests ensure high operational reliability.

Product Applications

• Industrial Power Distribution: Monitoring main circuits in unearthed (IT) networks.
• Renewable Energy: Solar PV inverters and battery energy storage systems (BESS).
• Variable Speed Drives (VSDs): Effectively monitors systems with connected converters and rectifiers.
• UPS & Battery Systems: Ensures continuous reliability in mission-critical power supplies.
• Railway & Mining: Specifically available in “W” variants for extreme climatic/mechanical conditions.

Precautions

• Qualified Personnel: Installation, configuration, and maintenance should only be performed by trained electrical engineering professionals.
• Measurement Setup: The device must be connected between the IT system (L1, L2, L3) and the protective earth (PE) conductor to function correctly.
• Voltage Limits: Do not exceed the rated voltage without using the appropriate Bender coupling devices (e.g., AGH series).
• System Integrity: Ensure that the device is correctly integrated into the IT system. If fault location is required, the iso685-D must be paired with compatible EDS44x series fault location modules.
• Maintenance: Regularly check the history memory and trend data via the web interface to identify insulation deterioration trends before they trigger a system-wide alarm.
