The Woodward 828 Digital Control Unit (P/N 9907-247, Rev K) is a precision electronic controller designed for demanding marine control system applications. Operating on a wide-range DC supply of 18–40 VDC at 40 watts, it provides stable, responsive digital control for engine governing and related automation functions onboard. With a maximum ambient rating of 70℃ and temperature classification code T4A, it is engineered to perform reliably in the elevated thermal environments typically found in engine rooms and machinery spaces. As a core component within a marine control system, it plays a critical role in maintaining engine performance, fuel efficiency, and operational safety across a range of vessel types.
Key Features
✓ Digital control architecture delivering accurate, repeatable governing performance for marine engine management applications.
✓ Rated 18–40 VDC input at 40 watts with a maximum ambient temperature of 70℃ and temperature code T4A, as specified in the original product data.
✓ Designed for integration within Woodward governor and engine control systems; compatibility with specific panels or controllers subject to confirmation based on vessel configuration.
✓ Suitable for installation in engine room environments; mounting arrangement and enclosure requirements depend on the specific installation context and applicable guidelines.
✓ Replacement and servicing should reference the Rev K specification to ensure correct configuration matching for the target control system.
Marine Applications
✓ Main engine governor control on merchant vessels including bulk carriers, tankers, and general cargo ships.
