Woodward 5503-335 MicroNet 5200 CPU Module

The Woodward 5503-335, also cataloged as the Woodward 5503-335 MicroNet 5200 CPU Module, operates as a dedicated hardware component for centralized turbine and engine control within MicroNet Plus Control platforms.

Hardware Specifications

Actuator Loop Feedback Response

The module integrates specialized processing pipelines to maintain tight deterministic execution of the actuator drive signals. Processing local analog inputs (4-20 mA, +-10 V) and speed pickups requires deterministic computational loops to prevent governor lag. The internal PowerPC-5200 architecture computes field-oriented vector control and pulse-width modulation (PWM) algorithms directly, minimizing loop latency to align with high-speed turbine governor response constraints and transient load-sharing demands.

Frequently Asked Questions

Q: What are the primary communication protocols supported by this CPU module for DCS/SCADA integration?

A: The module communicates via Ethernet TCP/IP, Modbus RTU, Modbus TCP, CANbus, and RS-232/485 serial interfaces to execute remote monitoring and command structures.

Q: Does this specific hardware assembly support dual-redundant deployment?

A: Yes, the MicroNet Plus platform architecture permits the integration of optional dual-redundant CPUs and power supplies to execute automatic failover tasks without losing real-time control capability.

Field Installation Guidelines

• Mounting and Orientation: Ensure the module is securely seated into the designated slot of the standard MicroNet rack frame. Fasten all captive screws to maintain grounding integrity and structural stability under high-vibration conditions.
• Wiring and Shielding: All I/O cables, including 4-20 mA loop lines and actuator drive cables, must utilize twisted, shielded pairs. Terminate shields only at the designated chassis ground point to prevent ground loops.
• Power and Grounding: Verify that the supply voltage matches the 18-32 VDC window before powering the unit. Ensure the rack enclosure connects to a low-impedance industrial earth ground.
