GE DS200TCEBG1AAB Relay Output Board – Mark VI Turbine Control Series
When a relay output board fails inside a GE Mark VI turbine control system, the consequences are immediate and severe: relay commands go unexecuted, protective trip circuits lose their actuation path, and the entire turbine unit may be forced into an unplanned shutdown. In power generation and heavy industrial environments, every hour of unplanned downtime translates directly into lost megawatt-hours, contractual penalties, and accelerated wear on ancillary equipment. The DS200TCEBG1AAB is not a peripheral accessory — it is the critical interface between the Mark VI controller’s logic and the physical world of contactors, solenoids, and trip relays that keep your turbine safe and operational.
The DS200TCEBG1AAB occupies a well-defined role within GE’s Mark VI Turbine Control platform, one of the most widely deployed distributed control architectures in gas turbine, steam turbine, and combined-cycle power plants worldwide. As a dedicated relay output board within the TCEB board family, it provides the hardwired discrete output channels that the Mark VI TMR (Triple Modular Redundant) and simplex configurations rely upon for protective and sequencing functions. Its global installed base — spanning utilities, petrochemical facilities, and industrial cogeneration plants across six continents — makes it one of the most sought-after spare boards in the Mark VI ecosystem.

- Broad Installed Base: One of the most common boards in the Mark VI family, meaning field engineers are familiar with its installation, diagnostics, and replacement procedures.
- Tested Before Shipment: Every unit sourced by Konmask.com undergoes functional verification prior to dispatch to minimize the risk of receiving a non-operational board.
Industry & Equipment Applications
- Power Generation: Gas turbine generators, steam turbine generators, and combined-cycle power plants using GE Mark VI control systems.
- Oil & Gas: Compressor trains, pipeline booster stations, and LNG facility turbine drivers controlled by Mark VI platforms.
- Petrochemical & Refining: Process-critical turbine-driven pumps and compressors where relay output integrity is a safety requirement.
- Industrial Cogeneration: Facilities operating GE-frame turbines with Mark VI control for combined heat and power applications.
- Marine & Offshore: Offshore platform power generation turbines and FPSO vessel turbine control systems.
System Integration & Compatible Parts
The DS200TCEBG1AAB operates within the broader GE Mark VI I/O board ecosystem. When planning a repair or spare-parts strategy, consider stocking compatible boards from the same TCEB and TCCA families. Related boards commonly used alongside the DS200TCEBG1AAB include other DS200-series I/O boards such as analog input boards, digital input boards, and communication interface boards. Always cross-reference your Mark VI system’s Bill of Materials (BOM) and the GEH-6421 Mark VI Control System Guide to confirm exact board revisions required for your specific turbine configuration. Contact our technical team for cross-reference assistance.
Our Quality Assurance Process
- Source Verification: Boards are sourced from decommissioned plant inventories, authorized distributors, or OEM surplus channels — never from unverified grey-market sources.
- Visual Inspection: Each board is inspected for physical damage, corrosion, burnt components, and connector integrity before acceptance into inventory.
- Functional Testing: Where test fixtures are available, boards undergo powered functional verification to confirm relay output operation.
- Anti-Static Packaging: All boards are shipped in ESD-safe bags with foam cushioning inside double-wall cartons to prevent transit damage.
- Documentation: Test reports and condition certificates are available upon request for critical spare applications.
