• B: Represents the B-rated functional product revision.

Hardware Specifications

Firmware Flash Compatibility & Backplane Communication

Integrated into the Mark V turbine control architecture, the DS200FCGDH1B coordinates high-speed data exchanges and signal conversions.

• Firmware Flash Compatibility: Requires compatible system software revisions to process digital signal processing card (DSPC) inputs and manage fiber-optic feedback signals.
• Backplane Bus Communication Velocity: Transmits multiplexed cell status information and system feedbacks via the drive's integrated VME backplane.
• I/O Density Scaling: Interfaces with six-pulse phase-controlled non-reversing bridges and processes multi-channel feedback data including frequency and voltage.

Frequently Asked Questions

Q: Does the assembly of the DS200FCGDH1B feature factory-drilled installation holes?

A: No, the base circuit board does not use factory-drilled holes, as it mounts in the Mark V Series VME Rack assembly using a metal mounting faceplate.

Q: Why is the B-rated revision classified as a functional product revision?

A: The B-rated revision introduces significant changes that enhance basic performance specifications and functionality without compromising aesthetics or durability.

Field Installation Guidelines

1. Power Isolation: Ensure all rack power supplies are completely de-energized before handling or installing the printed circuit board.
2. Electrostatic Discharge Protection: Utilize a properly grounded wrist strap connected to the designated cabinet earth point to protect sensitive onboard components.
3. Mechanical Mounting: Slide the board into the VME Rack assembly using its metal mounting faceplate, securing it properly to engage the backplane connectors.
4. Wiring Verification: Follow manufacturer-provided guidelines and illustrated manuals to ensure correct system wiring and fiber-optic connections for feedback signals.
