Function Features

• Multi-Signal Acquisition: Supports analog (AC/DC voltage/current), digital, and high-speed pulse signals—eliminating the need for multiple single-function modules and simplifying system architecture.
• Ultra-High Precision: 24-bit ADC and ±0.05% FS accuracy ensure precise measurement of critical parameters (e.g., power grid voltage, motor current), enabling accurate process control and performance analysis.
• High-Frequency Transient Capture: 500 kHz sampling rate captures fast electrical transients (e.g., voltage spikes, current surges in power systems), supporting post-fault analysis and predictive maintenance.
• High-Voltage Isolation: 2500 V AC channel isolation and 3000 V AC module isolation protect operators and control systems from high-voltage hazards in power grids or industrial high-power equipment.
• Advanced Signal Analysis: Built-in DSP algorithms calculate real-time parameters including RMS value, peak value, frequency, total harmonic distortion (THD), and phase angle—providing deep insights into equipment health.
• Redundant Power Support: Dual 24 V DC power inputs ensure uninterrupted operation if one power source fails, critical for mission-critical applications like power substation monitoring.
• IEC 61850 Compatibility: Native support for IEC 61850 (global power system automation standard) enables seamless integration with smart grids, substations, and power plant control systems.
• Comprehensive Diagnostics: Monitors module health (temperature, power supply), input signal integrity (overload, open circuit), and communication status. Fault data is logged with time stamps (≤1 μs accuracy) and transmitted to the central system for rapid troubleshooting.
• Rugged Design: Withstands -40°C to +70°C temperatures, vibration (up to 10 g peak), and shock (up to 30 g peak)—reliable in outdoor substations, mines, or heavy industry.

Application Scenarios

• Power System Automation:
  • Smart Substations: Monitors transformer voltage/current, detects grid transients (e.g., lightning surges), and calculates power quality metrics (THD, frequency deviation). IEC 61850 compatibility integrates with substation SCADA for grid stability.
  • Power Plants (Thermal/Hydro/Nuclear): Analyzes generator output parameters, turbine auxiliary system current, and boiler feedwater flow. High-precision data supports optimal power generation and equipment wear prediction.
  • Renewable Energy (Solar/Wind): Tracks inverter output voltage/current, grid connection frequency, and battery storage current. Captures voltage fluctuations from intermittent renewables to aid grid synchronization.
• Heavy Industry:
  • Steel & Metallurgy: Monitors rolling mill motor current, furnace temperature (via DC voltage signals from thermocouples), and conveyor belt encoder pulses. Detects current imbalances to prevent motor failure.
  • Mining: Tracks crusher motor current, conveyor belt speed (via pulse encoders), and hydraulic system pressure. Rugged design withstands dust, vibration, and extreme temperatures in underground/open-pit mines.
  • Petrochemical: Monitors pump motor current, pipeline pressure (via analog signals), and valve status (digital inputs). High-speed sampling captures pressure surges to prevent pipeline damage.
• Critical Infrastructure:
  • Data Centers: Monitors UPS output voltage/current, server rack power consumption, and cooling system pump status. Ensures stable power delivery to avoid data loss.
  • Railway Electrification: Analyzes traction substation voltage, train pantograph current, and track circuit signals. Detects power quality issues to maintain reliable train operation.
  • Water & Wastewater Treatment: Captures pump current, chemical dosage flow (via analog signals), and tank level switch status. Precise data optimizes treatment processes and reduces energy use.
