3. Product Introduction
Structure B — Architecture Hook
The WOODWARD 5464-414 is installed as a signal acquisition module inside a MicroNet control architecture, providing the interface between rotating equipment speed sensors and the main control processor. It converts MPU and proximity probe signals into high-resolution digital speed information used for turbine, compressor, and generator control functions.
This module sits in a safety-relevant measurement path. Confirm the channel configuration before replacement because similar MicroNet speed modules may use different sensor combinations. Inspect the backplane connector, module guides, and enclosure surfaces carefully (—which is critical for rotating equipment applications where inaccurate speed feedback can affect protection and synchronization functions).

WOODWARD 5464-414
The 5464-414 is designed for precise speed measurement rather than direct actuator control. It feeds processed speed information into the MicroNet controller where application logic handles regulation, protection, and sequencing.
5. ? Global Compliance & Industry Certifications
Expected regulatory considerations for the WOODWARD 5464-414 include:
- CE Mark — applicable for compliant MicroNet system installations.
- UL/cUL Recognition — may apply depending on system configuration and product revision.
- EMC Compliance — important for high-speed rotating equipment measurement environments.
- ATEX/IECEx — the module itself is not a standalone hazardous-area device; hazardous-area suitability depends on the complete control system, enclosure, and field installation.
- Marine Approvals (DNV GL / ABS / LR) — applicable only when included in approved marine control system configurations.
Speed measurement modules require strict documentation because incorrect sensor interfacing may affect overspeed protection and machine trip functions.
Verify specific lot certifications with OEM.
6. ? Long-Term Storage & Asset Preservation Guide
Store the 5464-414 in the original anti-static (ESD) shielding bag. The backplane connector contacts are sensitive to contamination and should remain covered until installation.
Maintain warehouse humidity below 60% RH. Excess moisture can degrade connector plating and PCB protection layers during long storage.
Before installation:
- Inspect the card edge connector for oxidation.
- Check the module housing and retaining clips for damage.
- Verify the channel configuration matches the removed module.
- Confirm the MicroNet software revision supports the replacement hardware.
- Perform controlled power-up testing after extended storage.
Keep the original module identification label visible in asset records. MicroNet systems often contain multiple similar-looking I/O cards.
7. Physical Installation Prerequisites
- Install only into the compatible Woodward MicroNet rack.
- Confirm rack slot assignment before insertion.
- Use ESD protection during handling.
- Verify MPU and proximity probe wiring separately.
- Ensure sensor cable shielding and grounding follow the approved design.
- Confirm connector seating before closing the cabinet.
Maintain cabinet airflow around the MicroNet rack. Leave sufficient clearance for heat dissipation and future module removal.
Avoid routing speed sensor wiring near high-current switching conductors.
8. Buyer’s FAQ (Logistics & Compliance Focus)
Q1. What HS Tariff Code is commonly used for WOODWARD 5464-414?
A: The final Harmonized System classification depends on customs interpretation and the declared function of the module. Industrial electronic control modules are commonly evaluated under electrical control equipment categories. Confirm the final HS code with your customs broker.
Q2. Does Country of Origin affect 5464-414 import documentation?
A: Yes. COO information supports customs clearance, equipment traceability, and maintenance audit records. Keep the OEM label, commercial invoice, packing list, and receiving inspection documents together.
Q3. Is shipping insurance recommended for this speed sensor module?
A: Recommended. The module contains precision electronic measurement circuitry and backplane contacts. Shock, vibration, moisture, or ESD exposure during transport may create intermittent faults.
Q4. Does the WOODWARD 5464-414 include the latest firmware pre-loaded?
A: The 5464-414 is a MicroNet hardware speed sensor module. Firmware compatibility depends on the MicroNet control platform and application software revision. Verify hardware revision requirements before installation.
Lifecycle Note: Woodward has issued product change documentation showing that older MicroNet digital speed sensor modules, including the 5464-414, were replaced by newer MicroNet speed sensor modules such as the 5466-5001 for equivalent applications. Verify replacement compatibility before substitution.
