REV: F
The Woodward MFR1 Multi Function Relay (part number 5448-885, Revision F) is a versatile relay module designed to perform converting, controlling, and monitoring functions within marine control systems. As a core component in shipboard automation and power management architectures, the MFR1 enables reliable signal processing and switching operations across a range of onboard plant systems. Its multi-function capability reduces the need for multiple discrete relay units, simplifying panel layouts and supporting efficient system integration in demanding marine environments.
Key Features
✓ Multi-function relay combining converting, controlling, and monitoring capabilities in a single unit, reducing component count in control panels.
✓ Variant identified as MFR1110B/G59, Revision F — specific voltage ratings, response times, and output configurations are subject to confirmation based on nameplate and system documentation.
✓ Suitable for integration within Woodward marine control architectures and compatible automation panels, subject to system configuration confirmation.
✓ Designed for installation within control cabinets or automation enclosures onboard; mounting orientation and environmental ratings should be verified against the applicable system drawing.
✓ Revision F designation indicates a defined hardware iteration; engineers replacing or upgrading should verify revision compatibility with the existing system before installation.
Marine Applications
✓ Power management and distribution control systems aboard commercial vessels, offshore platforms, and naval auxiliaries.
✓ Engine control and monitoring panels on merchant ships, including bulk carriers, tankers, and container vessels.
✓ Generator management and switchboard automation systems requiring reliable relay-based signal conversion and control logic.
✓ Integrated automation systems on offshore support vessels, tugs, and multipurpose vessels where Woodward control equipment is in service.
✓ Retrofit and upgrade projects replacing obsolete relay modules within existing Woodward-based marine control installations.
