Description
Product Overview
The GE DS200FCGDH1B is part of the Mark V Speedtronic control hardware family, developed for turbine-control and associated drive applications. Its FCGD function is focused on gate distribution and status handling rather than general-purpose PLC logic or field I/O. The board receives control information from the DSPC, processes signals associated with bridge operation, and returns status and feedback through the VME backplane. This role makes it a specialized component in the control chain for compatible power-electronics equipment.
In an LCI or related drive application, the FCGD board serves as an interface to a six-pulse, phase-controlled non-reversing bridge. It handles gate-related signals and multiplexed bridge-status feedback, while associated fiber-optic connections carry feedback from bridge interface circuitry. Diagnostic information and operating feedback are passed back into the control system for monitoring and control decisions. The board’s conformal coating is identified in supplier documentation, but the presence of a coating should not be treated as proof that a used board is electrically sound or suitable for a particular environment.
For maintenance teams, GE DS200FCGDH1B replacement decisions should be based on the complete board marking, functional revision, installed rack position, connector arrangement, and the receiving drive’s documentation. GE board identification guidance distinguishes functional revisions from other revision levels; some functional changes may not be downward-compatible. Do not substitute a visually similar FCGD board without confirming its approved use in the receiving assembly. Before commissioning, inspect the board and connectors, check the relevant fiber-optic paths, and follow the equipment-specific installation and test procedure.
Product Introduction
The DS200FCGDH1B provides gate-distribution and status-feedback functions in compatible GE Mark V drive and turbine-control equipment. Its interface with the DSPC and the six-pulse bridge places it in the power-conversion control path, where incorrect board selection can affect drive operation.
For a planned replacement, confirm the full part number and revision, the installed VME rack position, and all associated fiber-optic and backplane connections. Verify the receiving system’s approved configuration before installation.

Frequently Asked Questions
Q1. What does the DS200FCGDH1B do?
It is a Gate Distribution and Status card. It interfaces with DSPC control information, supports gate-related signaling for a compatible six-pulse bridge, and returns bridge-status and feedback information to the control system.
Q2. Can I hot-swap this board?
Do not assume hot-swap support. Follow the equipment-specific shutdown, isolation, and discharge procedures before removing the card. Drive and turbine-control equipment can contain hazardous voltages even after normal operation stops.
Q3. Does DS200FCGDH1B require firmware or parameter changes?
A universal firmware or parameter procedure has not been verified for this exact board. Check the receiving system’s documentation and record the existing hardware and configuration before replacement. Any post-installation tests should follow the approved maintenance procedure.
Q4. Can I replace it with DS200FCGDH1 or DS200FCGDH1A?
Not based on the base model alone. The functional revision can affect compatibility, and GE board-identification guidance notes that some functional revisions are not downward-compatible. Obtain confirmation for the exact receiving assembly before substituting another revision.
Q5. How do I verify the board’s condition and authenticity?
Request clear photographs of the board label, printed part number, revision markings, connectors, and PCB condition. Ask for the unit’s condition classification and a functional test report where available. A conformal coating or an intact appearance does not establish that the board has passed electrical testing.
Q6. Does the board work with every GE Mark V drive?
No. A shared product family does not guarantee that every board revision fits every drive configuration. Verify the rack position, DSPC relationship, bridge interface, connector arrangement, and approved part number for the specific equipment.
Q7. What warranty should I expect?
Warranty coverage depends on the seller and the unit’s condition. Confirm the warranty period, return policy, testing scope, and whether the supplied board is new surplus, used, refurbished, or repaired. Do not assume original manufacturer warranty coverage for legacy spare parts.
