Product Description

The Woodward 5453-278 is a robust 12-slot chassis engineered to house Triple Modular Redundancy (TMR) control systems, specifically designed for Woodward’s NetCon and MicroNet platforms. This rack serves as the critical backbone for high-availability turbine and compressor control applications, providing a VME-type backplane interconnect that ensures high-speed data integrity between processor and I/O modules. Unlike standard industrial enclosures, the 5453-278 features a modular block design with integrated thermal management and redundant power architecture to meet SIL 3 safety requirements.

Technical Specifications and Mechanical Data

Precise mechanical and electrical parameters are essential for system integration and cabinet layout. The Woodward 5453-278 adheres to the following specifications:
  • Part Number: 5453-278
  • Manufacturer: Woodward (a GE subsidiary)
  • Chassis Architecture: Modular 12-slot VME backplane system
  • Slot Configuration:
    • Total Module Slots: 12 positions
    • Standard Layout: 1 Transceiver slot + 11 I/O/Processor module slots
    • Power Supply Accommodation: 2 positions (each power module occupies 3 slot widths)
    • Effective Capacity: Up to 18 slot-equivalents when accounting for power module footprint
  • Modular Construction: Composed of three interconnected 6-slot blocks
  • Cooling System:
    • Type: Forced-air convection
    • Components: Onboard fans integrated into chassis blocks
    • Thermal Protection: Built-in thermal-switch for automatic shutdown upon overheating
    • Requirement: Full slot population with modules or blank filler panels is mandatory for proper airflow dynamics
  • Bus Standard: VME-type motherboard interconnect for high-speed deterministic communication
  • Mounting Dimensions:
    • Rack Width: Standard 19-inch rack mount
    • Depth: 14.5 inches (368 mm)
    • Height: 13.5 inches (343 mm)
  • Unit Weight: Approximately 25.05 lbs (11.4 kg)
  • Safety Features: Integrated thermal-shutdown switch prevents component damage during cooling failures

Installation and Thermal Management Guidelines

Proper installation of the Woodward 5453-278 is critical for maintaining system reliability. The chassis utilizes a forced-air cooling strategy where air is drawn through the module faces and exhausted by the onboard fans located in the chassis blocks. Engineers must ensure that all unused slots are fitted with approved blanking panels; operating the chassis with open slots disrupts the pressure differential, leading to localized hot spots and potential thermal tripping.
The modular block design allows for flexible configuration while maintaining structural rigidity. The internal VME bus provides the necessary bandwidth for TMR voting algorithms, ensuring that data synchronization between the three redundant channels occurs with minimal latency. The built-in thermal switch acts as a final fail-safe, cutting power to the backplane if internal temperatures exceed safe operating limits, thereby protecting expensive processor and I/O cards from heat-induced failure.
