Description
GE DS200XDSAG1ACC
Product Introduction
The GE DS200XDSAG1ACC is a legacy GE Speedtronic Mark V board associated with LM fuel and pressure measurement applications. The XDSAG designation appears in GE-related parts inventories specifically under LM fuel/pressure measurement, and the exact DS200XDSAG1ACC part number is listed as a Mark V board. This places the unit within the turbine-control instrumentation layer rather than the general-purpose PLC I/O category.
The GE DS200XDSAG1ACC should be treated as an application-specific turbine control component. Its job is tied to the measurement and processing of fuel/pressure information used by the Mark V control architecture. This is important when sourcing a replacement because a physically similar DS200 board is not necessarily electrically or functionally interchangeable. The complete part number, board artwork, revision markings, connectors, installed jumpers, and turbine application should all be checked against the existing installation.
For the GE DS200XDSAG1ACC, available online documentation is inconsistent. Some supplier pages describe it as an “excitation control board” and publish values such as 120/240 VAC input, 10 A output, and ±0.5% voltage regulation, while other records identify the same part number as LM fuel-pressure hardware. Those excitation-board specifications are not sufficiently corroborated to use as engineering specifications for DS200XDSAG1ACC.

Important specification note: Do not copy the frequently published 24 VDC, 5 VDC/6 A, 125 VDC, 12-channel, −40 to +85°C, or 0.85 kg values into an engineering datasheet without verifying the actual board documentation. Those values appear in secondary listings but are not adequately supported by the more reliable identification evidence.
DS200XDSAG1ACC
Main Features and Engineering Considerations
Mark V LM Fuel/Pressure Application
The primary identification of the XDSAG family is LM fuel/pressure measurement. This is the most useful functional classification when determining where belongs within a turbine control system.
Application-Specific Hardware
Unlike a modern universal PLC I/O module, the was designed around a specific GE turbine-control architecture. Its replacement should therefore be based on the turbine’s actual Bill of Materials, drawings, board revision, and connector configuration.
Exact Suffix Matters
The complete designation should be preserved during procurement. Do not assume that DS200XDSAG1A, another XDSAG board, or a visually similar DS200 board is an automatic substitute. A supplier’s statement that two versions are “equivalent” is not sufficient evidence for a turbine-control replacement.
Legacy Hardware Risk
The Mark V platform is legacy equipment. Current component listings show as a replacement/stock item rather than a contemporary automation module. That increases the importance of condition assessment, board revision verification, connector inspection, and functional testing before installation.
Documentation Conflicts
This part number illustrates a common procurement problem with older GE boards: reseller databases often reuse generic specifications from unrelated DS200 or Mark-series boards. One listing calls an excitation control board, while another describes it as a PLC spare with Ethernet/IP, PROFINET, and Modbus. Those descriptions conflict with the stronger XDSAG/LM fuel-pressure identification and should not be accepted without OEM documentation.
Field Replacement
Before removing the original board, record connector positions, cable labels, jumper settings, board revision, and any daughterboard or terminal-board connections. Photographing the installed assembly is worthwhile because Mark V cabinet wiring is highly application-dependent.
Application Scenarios
- LM-Series Gas Turbines: Fuel and pressure measurement within GE Speedtronic Mark V installations.
- Mark V Turbine Control: Application-specific instrumentation and control hardware.
- Fuel-System Monitoring: Processing of pressure-related information used by the turbine control architecture.
- Legacy Turbine Maintenance: Replacement of an existing identified in the turbine BOM or cabinet documentation.
- Control-System Spare Inventory: Critical spare holding for existing Mark V installations.
Engineer’s Guide: Field Pitfalls
Do not classify it as an excitation board based on a reseller title. The stronger identification evidence places the XDSAG family under LM fuel/pressure measurement.
Do not rely on generic DS200 electrical specifications. Voltage, current, channel count, and temperature values found on unrelated supplier pages can be incorrectly copied between GE board numbers.
Verify the complete part number. should be matched character-for-character against the existing board.
Check the board artwork and revision. The G1ACC suffix is part of the procurement identity.
Verify the turbine application. LM2500, LM5000/LM6000 and other Mark V configurations can have application-specific hardware arrangements.
Inspect connectors and wiring before power-up. A replacement board does not correct damaged harnesses, incorrect termination, or cabinet wiring problems.
Preserve configuration information. Photograph jumpers, switches, connector locations, and labels before removing the original unit.
Do not accept unsupported protocol claims. Claims that this board directly supports Modbus TCP, EtherNet/IP, or PROFINET are not supported by the identification evidence reviewed for this exact part number.
Frequently Asked Questions
What is GE ?
The is a GE Speedtronic Mark V DS200-series board associated with LM fuel/pressure measurement applications.
Is an excitation control board?
The available evidence does not support using that as the primary classification. Some reseller pages call it an excitation control board, but other records specifically identify the XDSAG family as LM fuel/pressure measurement.
Is a standard PLC I/O module?
No. It should be treated as application-specific GE Mark V turbine-control hardware rather than a generic PLC I/O module.
Is interchangeable with DS200XDSAG1A?
Do not assume interchangeability. The complete suffix and revision should be compared with the turbine’s approved parts list and engineering documentation.
What is the operating voltage of ?
A reliable exact operating-voltage specification could not be established from the available documentation. Several online listings provide conflicting voltage figures, so the board documentation and actual Mark V wiring should take precedence.
What turbine systems use this board?
The XDSAG family is associated with GE Speedtronic Mark V LM fuel/pressure measurement applications.
Procurement Note
For a , the safest purchasing specification is the complete part number plus the existing board’s artwork/revision and turbine application. Ask for clear photographs of the front and rear PCB markings, connector arrangement, and revision information before accepting a replacement.
The main procurement risk is misidentification. Current web listings contain three materially different descriptions: LM fuel/pressure measurement, excitation control, and generic PLC spare. The XDSAG family identification and GE-related inventory evidence support the LM fuel/pressure measurement classification, while the conflicting excitation and generic PLC specifications should be treated as unverified.
For an operating Mark V turbine, verify the replacement against the site-specific GE drawings, BOM, board revision, connector wiring, and functional test procedure before installation.
