WOODWARD 5441-413 – Relay Interface Module | Governor & Turbine Control Platform
Engineering Background
WOODWARD is a globally recognized leader in energy control solutions, with over a century of engineering heritage in governor systems, turbine controls, and power management. The 5441-413 Relay Interface Module is purpose-engineered for integration within WOODWARD’s modular governor control architecture, providing reliable discrete I/O relay switching in demanding industrial environments where signal integrity and system uptime are non-negotiable.
Product Positioning
The 5441-413 serves as a critical bridge between the governor controller and field-level actuators, solenoids, and alarm circuits. It is specified by control engineers in power generation, oil & gas, and marine propulsion applications where deterministic relay response and robust isolation are required. This module is a direct-fit replacement and expansion component for WOODWARD governor control panels.

Proven Application Environments
- Gas Turbine Power Plants — Relay interface for fuel valve solenoids, trip circuits, and alarm annunciators in WOODWARD governor-controlled turbines.
- Steam Turbine Control Panels — Discrete output switching for steam admission valves and overspeed protection relay logic.
- Diesel Generator Sets — Integration with genset governor panels for start/stop relay sequencing and load-sharing signal conditioning.
- Marine Propulsion Systems — Relay I/O for bridge control and engine room governor panels on vessels requiring DNV or ABS compliance.
- Oil & Gas Compression Stations — Compressor driver governor control with relay outputs to ESD (Emergency Shutdown) systems.
- Industrial Cogeneration (CHP) — Relay interface between WOODWARD controllers and utility interconnect protection relays.
Engineering Advantages
- Direct OEM Compatibility — Designed and manufactured by WOODWARD; plug-and-play replacement within existing 5441-series control panels with no firmware modification required.
- Galvanic Isolation — Protects the governor controller backplane from field-side voltage transients, ground loops, and inductive kickback from relay coils.
- Deterministic Switching — Relay response time is consistent and predictable, critical for trip and protection logic where millisecond-level timing affects turbine safety.
- Wide Temperature Range — Rated for harsh industrial environments including outdoor substations and unheated machinery spaces.
- Modular Architecture — Slots into WOODWARD’s modular governor chassis, enabling hot-swap maintenance and incremental I/O expansion without system shutdown.
- Long Service Life — Industrial-grade relay contacts rated for high cycle counts, reducing maintenance intervals in continuous-duty applications.
System Architecture & Signal Flow
In a typical WOODWARD governor control system, the 5441-413 Relay Interface Module occupies a dedicated I/O slot within the governor chassis. The signal flow is as follows:
- Controller Command — The governor CPU issues a discrete output command via the internal backplane bus.
- Relay Interface Module — The 5441-413 receives the logic-level signal and energizes the corresponding relay coil, providing galvanic isolation.
- Field Output — The relay dry contact closes, switching the field-side circuit (solenoid valve, alarm horn, trip relay, or indicator lamp).
- Feedback / Status — Relay status may be monitored by the governor controller for diagnostics and fault annunciation.
This architecture ensures that field-side faults (short circuits, ground faults) do not propagate to the governor controller logic, maintaining system integrity during fault conditions.
Sourcing & Quality Verification
