Configured for high-speed gas turbine regulation and real-time control execution in MicroNet Plus architectures, the WOODWARD 5466-1045 (5466-1045 MicroNet Plus Digital Controller Module) provides direct physical/electrical execution.

Hardware Specifications

VMEbus Communication Velocity and Firmware Execution

The module utilizes an onboard CPU5200 engine operating alongside 128 MB DDR RAM and 64 MB Flash memory to execute real-time GAP (Graphical Application Program) control logic. Installed directly into the main chassis, the module communicates via high-velocity VMEbus backplane channels to process field I/O data. Designed strictly for simplex system topologies, the card optimizes backplane bus communication velocity and cycle times by eliminating inter-CPU synchronization overhead.

Frequently Asked Questions

Q: Does the 5466-1045 support expansion chassis configurations via Real-Time Network (RTN) ports?

A: No. The 5466-1045 is designed strictly for main-rack simplex operation and does not feature RTN ports or expansion chassis bridging capabilities.

Q: How does the controller handle remote reset commands from field safety circuits?

A: The module incorporates dedicated onboard circuitry designed to process an external +24 VDC remote reset signal, allowing operators to clear latched system fault conditions.

Field Installation Guidelines

1. Power down the MicroNet Plus chassis prior to inserting or removing the module from the rack backplane slot.
2. Slide the module along the card guides into slot A1 of the main rack until the backplane connectors seat firmly.
3. Tighten top and bottom faceplate thumb screws to establish solid chassis ground contact and prevent vibration loosening under MIL-STD-810C conditions.
4. Route shielded Ethernet and RS-232 serial communication lines through dedicated low-voltage wire trays separated from high-power AC conductors.
5. Maintain clear ventilation channels above and below the card cage to support ambient thermal cooling across the -40 to 85 deg C operating range.
