Key Applications & Use Cases
Gas Turbine Control: Provides stable, redundant power to MicroNet controllers managing fuel flow, ignition sequencing, and turbine speed regulation in combined-cycle and simple-cycle plants.
Power Generation: Supports critical control loops in generator protection, excitation control, and synchronization systems where power continuity is non-negotiable.
Oil & Gas Processing: Powers distributed control systems (DCS) monitoring compressor stations, pipeline SCADA networks, and offshore platform automation.
Industrial Manufacturing: Ensures reliable operation of process control systems in chemical plants, refineries, and heavy manufacturing facilities requiring 24/7 uptime.
Why Choose TMR Architecture?
Triple Modular Redundancy eliminates single points of failure by running three parallel power channels. If one channel experiences a fault, the system automatically switches to healthy channels without interrupting control operations—critical for safety-instrumented systems (SIS) and high-availability applications.
Installation & Integration Solutions
The 5501-380 integrates seamlessly with Woodward MicroNet TMR control platforms. Installation requires standard 120V AC or DC input wiring, with output connections to MicroNet backplane power buses. Hot-swappable design allows maintenance without system shutdown. Diagnostic LEDs provide real-time status indication for each redundant channel.
Frequently Asked Questions
Q: Can I use both AC and DC input simultaneously?
A: No, select either 120 VAC or 120 VDC input based on your facility's available power infrastructure.
Q: What happens if one power module fails?
A: The TMR architecture automatically maintains operation using the remaining two healthy modules while alerting operators to replace the failed unit.
Q: Is this compatible with non-Woodward control systems?
A: The 5501-380 is specifically designed for Woodward MicroNet systems and may not interface with third-party controllers.
Q: What is the expected service life?
A: Under normal operating conditions, expect 10-15 years of reliable service with proper maintenance and environmental controls.
Warranty & Support
All Woodward 5501-380 units include a 12-month manufacturer warranty covering defects in materials and workmanship. Technical support and replacement parts are available through authorized Woodward service centers worldwide.
