The Woodward 5466-419, also cataloged as the 5466-419 CPU Processor Module, operates as a dedicated hardware component for microprocessor-based control execution and real-time system monitoring within MicroNet Plus control platforms. Driven by an onboard Intel Atom processor paired with 2 GB DDR3 RAM and 8 GB eMMC flash memory, the module executes high-speed control algorithm loops and systemic diagnostic tasks across the backplane chassis using a 24 VDC power supply.

Hardware Specifications

Actuator Loop Feedback Response Dynamics

The CPU module coordinates real-time deterministic tasks to ensure ultra-low latency in actuator loop feedback response routines. By processing critical control matrices directly through the Intel Atom engine and high-bandwidth DDR3 RAM, the module executes task loops with sub-millisecond execution times. This processing capacity minimizes phase delay across high-speed governor and turbine valve control loops, ensuring precise actuator positioning and immediate transient recovery under dynamic load changes.

Frequently Asked Questions

Q: How does the integrated 8 GB eMMC flash memory handle onboard data logging and firmware storage?

A: The non-volatile 8 GB eMMC flash memory stores the main control operating system, application logic files, system fault logs, and historical trend data without requiring continuous battery power.

Q: Can this CPU module be replaced or swapped without powering down peripheral field I/O devices?

A: Module replacement must be performed in accordance with MicroNet Plus backplane power protocols; while peripheral field loops remain powered by external 24 VDC field supplies, powering down or bypassing the active control rack is required before removing or reseating the main CPU card.

Q: What mechanisms ensure stable CPU operation in high-temperature industrial environments?

A: The module is engineered with industrial-grade silicon components rated across an extended operating range of -40 deg C to +85 deg C, utilizing passive conduction heat sinking to dissipate thermal energy within standard MicroNet chassis airflow profiles.

Field Installation Guidelines

1. Power down the targeted MicroNet Plus chassis or sub-rack power supply module before inserting the CPU processor unit into the designated main controller slot.
2. Align the module circuit board with the top and bottom chassis card guides, sliding the module firmly inward until the backplane multi-pin edge connectors engage.
3. Tighten the top and bottom panel captive mounting screws to achieve full electrical grounding to the rack chassis frame.
4. Route all front panel communication and network cables with proper strain relief, maintaining a minimum 50 mm bend radius to prevent fiber or wire degradation.
5. Apply 24 VDC main power to the rack and observe the front panel diagnostic status LEDs to confirm successful boot sequence completion.
