Description

Woodward 8444-1084

Technical Specifications

  • Product Series: MFR300 / 8444 Series.
  • Processor Speed: High-speed 50 MHz microprocessor.
  • Memory: 53 MB for program and data storage.
  • Display: Integrated two-line text display (24 characters per line).
  • Power Supply: Standard 220V AC, 50Hz.

Functional Features

  • Dual Operating Modes: Features distinct Programming Mode for configuration and Running Mode for automated control.
  • Actuator Control: Manages single or dual separate stage actuators for precise valve positioning.
  • Menu-Driven Interface: Intuitive, menu-based software simplifies setup, tuning, and diagnostics.
  • Power Quality Monitoring: Continuously monitors electrical parameters to ensure grid stability.

Application Scenarios
Extensively applied in industrial steam turbines, turbo-generators, and wind power generation systems.

Performance Parameters

  • Environmental Tolerance: Operates reliably in ambient temperatures from 0°C to 60°C.
  • Humidity Resistance: Rated for up to 60% non-condensing relative humidity.

Material Composition
Housed in a robust, module-style metal enclosure. Internal printed circuit boards are manufactured with industrial-grade components and protective conformal coatings.

Structural Characteristics
Weighs approximately 6.5 kg with a compact, modular form factor. Features a front-panel operator interface for local monitoring and adjustment without a laptop.

Working Principle
The module samples AC voltage and current waveforms via high-precision analog-to-digital converters. Its microprocessor executes complex algorithms to calculate power quality metrics and executes control logic to output relay signals or analog commands to actuators and breakers.

Installation Requirements
Install in a climate-controlled control room or panel. Requires the installation of the TOOLKIT software (version 4.4 or higher) and the corresponding SID file for parameter configuration via the designated USB data cable.

Usage Precautions

  • Always use the official Woodward TOOLKIT software for parameter configuration.
  • Ensure the power supply is stable and properly grounded before energizing.
  • Regularly back up the configuration parameters to prevent data loss.
