Product Introduction (No Fluff)

The DS200DMCBG1AKG is a DMC DUP processor board for the GE Mark V Speedtronic turbine control system. It provides redundant processing capability and I/O communication for gas and steam turbine control applications.

The board belongs to the DS200 series of Mark V printed circuit boards, with the “DMC” function code identifying it as a DMC processor card. The Mark V platform is a widely deployed turbine control system used in gas turbine, steam turbine, and combined cycle power generation applications worldwide.

The DS200DMCBG1AKG features three 26-pin connectors, one 40-pin connector, and 19 configurable jumpers for field customization. Two LED indicators (CR2 and CR12) provide visual status feedback. When replacing this board in the field, jumper settings must be matched to the original board to ensure proper operation. Note that not all jumpers are user-configurable — some are designated for factory testing only and should not be adjusted.

This board is commonly found in utility power generation facilities, cogeneration plants, and industrial turbine installations running the Mark V control platform.

 

QA & Testing SOP (Dynamic & Transparent)

Each surplus unit undergoes:

1. Part Number Verification: Confirm the label reads DS200DMCBG1AKG. Check for GE markings and board revision.
2. Visual Inspection: Inspect the PCB surface, connectors, jumper headers, LEDs, and conformal coating for corrosion, damage, or contamination.
3. Connector Check: Verify all three 26-pin connectors and the 40-pin connector are intact, with no bent pins or damaged contacts.
4. Jumper Verification: Inspect all 19 JP-series jumpers. Document their positions for reference during installation. Note which jumpers are factory-test only.
5. LED Check: Confirm both LED indicators (CR2 and CR12) are present and not damaged.
6. Mechanical Fit Check: Verify the board profile matches the expected form factor for the Mark V rack.
7. Continuity Check: Where possible, verify continuity across key connector pins and jumper positions.
8. Packaging: Pack in anti-static bags with foam cushioning. Protect connectors and jumpers during transit.

 

Installation Pitfalls & Guide (Engineer to Engineer)

Match jumper settings exactly. Before removing the old board, document all 19 jumper positions by their printed identifiers (JP1, JP2, JP3, etc.). The replacement board must match these exactly. Component placement may differ between revisions, but the jumper identifiers on the PCB are the reference — match by identifier, not by physical location.

Do not adjust factory-test jumpers. Not all 19 jumpers are user-configurable. Some are designated for factory testing only. Reference the original board documentation to identify which jumpers should not be changed.

Use proper ESD protection. Always wear a grounded wrist strap when handling Mark V boards. Connect the strap to an unpainted metal surface to prevent electrostatic discharge damage.

Handle connectors carefully. The 26-pin and 40-pin connectors use pins that can be easily bent. When disconnecting, pull straight out and avoid applying lateral force.

Verify LED status after installation. After powering up, check the CR2 and CR12 LEDs for normal status indication.

Document board location. Record the rack and slot position of the board. This simplifies future troubleshooting and replacements.

Installation Steps:

1. Pre-install: Confirm part number DS200DMCBG1AKG. Document all jumper positions on the existing board by their PCB identifiers.
2. Power Down: Follow proper turbine control system shutdown procedures before removing any boards.
3. Remove Old Board: Disconnect all connectors. Remove the board from the rack.
4. Configure New Board: Set all user-configurable jumpers on the replacement board to match the original by PCB identifier.
5. Install Board: Seat the board in the correct rack slot. Reconnect all connectors securely.
6. Commission: Follow Mark V system startup procedures. Verify LED status (CR2, CR12). Confirm normal turbine control operation.

 

Technical FAQ

1. What is the DS200DMCBG1AKG? It is a DMC DUP processor board for the GE Mark V Speedtronic turbine control system, providing redundant processing and I/O communication.

2. What system is it used in? It is used in GE Mark V turbine control systems for gas turbines, steam turbines, and combined cycle power generation.

3. How many connectors does it have? It has three 26-pin connectors and one 40-pin connector.

4. Does it require jumper configuration? Yes. The board has 19 jumpers, but not all are user-configurable. Some are factory-test only. Match user-configurable jumpers to the original board by their PCB identifiers.

5. What do the LEDs indicate? The board has two LEDs labeled CR2 and CR12 that provide visual status feedback.

6. Can I substitute it with DS200DMCAG1A? These are different variants within the DMC family. DS200DMCAG1A is an earlier variant. Always confirm compatibility with your specific Mark V system before substituting.

7. Is this product still in production? The Mark V platform has been superseded by newer GE turbine control systems (Mark VI, Mark VIe). DS200DMCBG1AKG is typically available as surplus or refurbished stock.

8. What warranty do you offer on surplus stock? Terms vary by condition and availability. For surplus industrial modules, we typically provide a short functional guarantee. Confirm details at time of order.
