Function Features

• Ultra-High-Speed Sampling & Processing: 1 MHz sampling rate and 24-bit ADC ensure capture of fast transients (e.g., voltage spikes, current surges in power systems) and precise measurement of high-frequency signals—critical for fault analysis and predictive maintenance.
• Multi-Signal Compatibility: Supports AC/DC voltage, AC/DC current, and digital pulse signals, eliminating the need for multiple single-function modules and simplifying system architecture.
• High-Voltage Isolation: 2500 V AC channel isolation and 3000 V AC module isolation protect both the module and connected control systems from high-voltage hazards in power grids or industrial high-power equipment.
• Advanced Signal Analysis: Built-in DSP algorithms calculate key electrical parameters in real time, including RMS value, peak value, frequency, total harmonic distortion (THD), and phase angle—providing deep insights into equipment performance.
• Fault Detection & Logging: Automatically detects abnormal signals (e.g., overvoltage, overcurrent, frequency deviation) and logs fault data with time stamps (accuracy ≤ 1 μs). This data is stored locally and transmitted to the control system for post-fault analysis.
• Redundant Power Support: Accepts dual 24 V DC power inputs, ensuring uninterrupted operation even if one power source fails—critical for mission-critical power or industrial applications.
• IEC 61850 Compatibility: Native support for IEC 61850 (the global standard for power system automation) enables seamless integration with smart grids, substations, and power plant control systems.
• Remote Monitoring & Configuration: Configurable via web interface or ABB’s dedicated software (e.g., ABB Control Builder Plus). Users can adjust sampling rates, set fault thresholds, and retrieve logged data remotely, reducing on-site maintenance needs.
• Rugged Environmental Adaptability: Operates in -40°C to +70°C temperatures and resists vibration (up to 10 g peak) and shock (up to 30 g peak), ensuring reliability in harsh settings like outdoor substations, mines, or heavy industry.

 Application Scenarios

• Power System Automation:
  • Smart Substations: Monitors high-voltage transformer voltage/current signals, detects transients (e.g., lightning-induced surges), and calculates THD to ensure grid stability. IEC 61850 compatibility enables integration with substation SCADA systems.
  • Power Plants (Thermal/Hydro/Nuclear): Analyzes generator output voltage/current, turbine auxiliary system electrical parameters, and grid connection signals. Fault logging supports rapid diagnosis of electrical issues (e.g., generator overload).
  • Renewable Energy (Solar/Wind): Tracks inverter output current/voltage, grid connection frequency, and power quality. High-speed sampling captures voltage fluctuations caused by intermittent renewable energy sources, aiding in grid synchronization.
• Industrial High-Power Applications:
  • Heavy Industry (Steel, Mining): Monitors electrical parameters of large motors (e.g., crusher motors, rolling mill motors), detects current imbalances or overloads, and predicts motor wear via harmonic analysis.
  • Railway Electrification: Analyzes traction substation voltage/current signals, detects power quality issues (e.g., voltage dips), and ensures stable power supply to electric trains.
• Precision Industrial Monitoring:
  • Manufacturing (Semiconductor, Automotive): Monitors power supply signals for high-precision equipment (e.g., semiconductor lithography machines, robotic welding systems). High accuracy ensures stable voltage/current delivery, preventing product defects.
  • Data Centers: Tracks UPS (Uninterruptible Power Supply) output parameters, server rack power consumption, and electrical system frequency. Fault detection triggers rapid backup power activation to avoid data loss.
