Industry Applications
The Woodward 5503-335 is ideal for upgrading gas turbine control systems in power generation and industrial gas compression. Its robust design supports reliable operation in harsh environments. For example, in a combined-cycle plant, this CPU module can replace an older MicroNet processor to improve computational performance and maintain compatibility with existing I/O and communication networks.
Installation & Setup Guidance
When installing the Woodward 5503-335, use an expansion chassis equipped with a Remote RTN module. Secure the unit using its rugged connectors. Ensure the ambient temperature stays within 0 to +55 °C. The front faceplate includes ten LEDs (TX/RX, LINK, STANDBY, SYSCON, RUN, IOLOCK, LVCC, WATCHDOG, CAN #1/#2, FAULT) for quick status monitoring during startup.
Compatibility & Integration
The Woodward 5503-335 supports multiple industrial communication protocols including Modbus, CANbus, and PROFIBUS. It also features dedicated CAN and Real-Time Network ports. This allows seamless integration with existing PLCs, DCS, and SCADA systems in gas turbine applications. The module can be used as a direct replacement for earlier 5200 series CPUs.
Selection Guide & Purchasing Advice
Before purchasing the Woodward 5503-335, verify that your system uses a MicroNet expansion chassis with a Remote RTN module. Ensure the model number matches exactly – substitutes are not compatible. For reliable supply, choose an experienced distributor like PLC Source PRO, which offers certified tested units and technical support.
