Description
The Woodward 5501-467 is a Simplex Power Supply Module manufactured by Woodward, Inc. for the MicroNet Digital Control platform. In field deployments across industrial turbine control systems, compressor drives, and power generation skids, this module converts incoming facility AC/DC power into regulated internal logic voltages to drive CPU processors and I/O expansion modules in single-channel chassis configurations.

Engineering & Integration Guidance
When installing or replacing the 5501-467 module within a MicroNet chassis, observe the following technical parameters:
- Input Line Verification: Confirm incoming supply voltage matches module hardware configuration before energizing the cabinet to prevent overvoltage damage to input filter circuits.
- Rack Power Safety: Completely de-energize the main rack power supply distribution before removing or inserting the module to prevent electrical arcing, backplane bus faults, or connector pin stress.
- Electrostatic Discharge (ESD) Handling: Wear a grounded antistatic wrist strap and handle the module assembly by its frame edges and faceplate to prevent static discharge to onboard microchips.
Frequently Asked Questions
What system architecture utilizes the Woodward 5501-467?
This power supply unit is designed specifically for Woodward MicroNet Simplex (single-channel) digital control chassis deployed in turbomachinery and generator management systems.
Can this module be hot-swapped?
No. Standard MicroNet Simplex maintenance protocols require powering down the chassis before extracting or installing internal power supply boards.
How does a Simplex power supply differ from a TMR power supply in MicroNet systems?
A Simplex power supply powers a single non-redundant rack architecture, whereas TMR (Triple Modular Redundant) power supply modules operate in fault-tolerant, load-sharing configurations across redundant backplane buses.
