WOODWARD 5453-279

Technical Specifications:

  • Brand: Woodward
  • Model: 5453-279
  • Product Type: Safety System Accessory / Speed Monitoring Unit
  • Input Signal: Magnetoelectric sensor signal
  • Input Frequency Range: 3000-6000 Hz
  • Minimum Input Signal: ≥1.5 Vrms
  • Power Supply: 12-24 VDC (Wide range)
  • Operating Temperature: -40°C to +85°C
  • Storage Temperature: -40°C to +90°C
  • Humidity: 5% to 95% (non-condensing)
  • Protection Rating: IP20 (Panel Mount)
  • Dimensions: 120 mm (W) × 100 mm (H) × 80 mm (D)
  • Weight: Approx. 0.75 kg

Functional Features:

  • High-Precision Monitoring: Accurately collects speed signals to detect overspeed or underspeed conditions.
  • Safety Interlock: rapidly outputs interlock trigger signals to the safety host for emergency shutdown.
  • Signal Isolation: Built-in isolation circuits prevent ground loops and transient voltage impacts.
  • Self-Diagnosis: Continuous monitoring of internal status and sensor health.

Application Scenarios:

  • Petrochemical plants.
  • Marine power systems.
  • Generator sets and turbine protection.
  • Hazardous area applications requiring SIL compliance.

Performance Parameters:

  • Insulation Strength: ≥500 VAC
  • Response Time: Fast fault signal transfer for emergency stops.
  • MTBF: High industrial standard for continuous operation.

Material Composition:

  • Sealed industrial enclosure.
  • High-reliability electronic components with surge suppression.

Structural Features: Compact sealed structure with anti-loosening terminals. Features LED status indicators for Power, Operation, and Fault states.

Working Principle: The unit acquires speed pulses from magnetic sensors, filters and isolates the signal, and compares it against preset safety thresholds. If a threshold is breached, it triggers a safety interlock signal to the main controller.

Installation Requirements:

  • Install on a standard 35mm DIN rail.
  • Ensure the installation environment is free from excessive conductive dust.
  • Connect shielded cables for sensor inputs to prevent interference.

Usage Notes:

  • Compatible with Woodward MicroNet TMR systems.
  • Verify the sensor type matches the input requirements.
  • Regularly test the safety interlock function during maintenance windows.
