FUNCTIONAL DESCRIPTION:
The 5441-663 Relay Interface Module is a heavy-duty industrial switching unit designed specifically for Woodward MicroNet and MicroNet TMR control systems. It acts as a robust intermediary, allowing the system's low-current digital outputs to control high-current field devices such as large solenoids, motor starters, and heavy-duty actuators. This module is engineered to provide high-capacity switching while ensuring that the sensitive electronic processors within the control chassis remain electrically isolated from field-side noise and voltage spikes. Its durable design makes it a staple in power generation and industrial turbine control, where reliability is non-negotiable.
HIGH-CAPACITY SWITCHING AND ISOLATION:
Equipped with 8 independent channels, each featuring 10 amp-rated contacts, the Module is built for power-heavy applications. The module utilizes high-grade electromagnetic relays to provide complete galvanic isolation, preventing ground loops and protecting the backplane from back-EMF generated by inductive loads. This ensures that a failure or electrical fault in the field equipment does not propagate back to the main control system. Each channel operates independently, allowing for a mix of different voltages and load types to be managed by a single interface module.
SYSTEM RELIABILITY AND DIAGNOSTICS:
The Module is fully compatible with Woodward�s Triple Modular Redundant (TMR) architectures, where it can participate in hardware voting schemes to ensure continuous uptime. Its physical design includes a rugged aluminum faceplate that serves as a heat sink, facilitating natural convection cooling to maintain performance in high-temperature engine rooms. The module is also equipped with front-panel status indicators that allow maintenance personnel to quickly verify the state of each relay and the health of the input signal, significantly reducing troubleshooting time during routine inspections or system faults.

What is the Woodward 5441-663?
It is an 8-channel Relay Interface Module used in MicroNet and MicroNet TMR systems. It converts low-power digital signals from the control system into high-power contact closures for driving field devices. This module is essential for applications requiring 10 Amp switching capacity across multiple independent channels.
What is the primary use of the Woodward 5441-663?
The module is primarily used as a power interface between a turbine control system and heavy-duty field hardware. It is commonly found in environments where the control system must manage high-current solenoids, motor contactors, or alarm panels. Its role is to safely bridge the gap between sensitive logic and high-power electrical loads.
Does this module support redundant configurations?
Yes, the Module is designed to work seamlessly within MicroNet TMR systems. In these configurations, it can be used in conjunction with TMR I/O modules to provide high-availability control through redundant signal paths and voting logic. This ensures that the system remains operational even if a single control signal is lost.
What is the contact rating for this module?
Each of the 8 relay channels on the Module is rated for up to 10 Amps. This high-capacity rating allows the module to directly switch many industrial loads that would otherwise require additional external interposing relays. The independent nature of the contacts allows for significant flexibility in wiring different voltage levels across the module.
