Woodward 5466 Series Technical Notes

The Evolution of 5466 Series Architecture

The 5466 Series was introduced as part of Woodward's transition from analog governor platforms (505 Series) to fully digital, microprocessor-based control in the late 1980s and early 1990s. Early revisions used parallel backplane communication with proprietary Woodward bus protocols, limiting interoperability to same-generation hardware. Mid-generation revisions introduced enhanced EEPROM-based parameter storage, replacing battery-backed RAM and significantly improving configuration retention across power cycles.

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.
