Description
WOODWARD
PART NO: 8272-683
DIGITAL REFERENCE UNIT
POWER SUPPLY: 10-45VDC
REV: T
The Woodward Digital Reference Unit (Part No. 8272-683, Rev T) is a precision control component designed to provide stable digital reference signals within governor and engine control systems aboard commercial and industrial vessels. Operating from a wide-range DC power supply of 10–45VDC, this unit is well-suited to the variable power conditions commonly encountered in marine environments. As part of a Marine Control System, it plays a critical role in maintaining accurate setpoint references for speed, load, or process control loops, contributing directly to engine stability and operational reliability at sea.
Key Features
✓ Functions as a digital reference signal source within governor and engine management control architectures, supporting precise setpoint regulation.
✓ Wide-range DC power input of 10–45VDC allows compatibility with varying onboard power supply configurations, subject to system confirmation.
✓ Revision T designation indicates a mature, updated hardware revision — specific changelog details should be confirmed against Woodward documentation for the application.
✓ Compact control unit suitable for installation in engine control rooms or control panels; exact mounting dimensions and environmental ratings should be confirmed prior to installation.
✓ Designed for integration with Woodward governor systems and compatible control platforms; system compatibility is subject to confirmation based on vessel configuration and controller version.
Marine Applications
✓ Main engine governor control systems on merchant vessels, tankers, and bulk carriers requiring stable digital speed or load reference signals.
✓ Auxiliary engine and diesel generator control panels where accurate reference units support load sharing and frequency regulation.
✓ Offshore platform supply vessels and offshore support vessels with Woodward-based propulsion or power management control systems.
✓ Naval and coast guard vessels utilising Woodward governor architectures for engine speed control and operational precision.
✓ Ferry and RoPax vessels where engine control system reliability is essential for manoeuvring, port approach, and continuous service operations.
Why Marine Engineers Choose
