GE DS200TCDA-HBHE – Analog I/O Terminal Board | Mark VI Turbine Control Platform
Engineering Background
The DS200TCDA-HBHE is a critical analog input/output terminal board designed for General Electric’s Mark VI Turbine Control System — one of the most widely deployed turbine management platforms in power generation and industrial gas turbine applications worldwide. As part of the Mark VI I/O subsystem, this board serves as the physical interface layer between field instrumentation and the Mark VI controller, handling precision analog signal conditioning, isolation, and routing for turbine protection and control loops.
Product Positioning
Engineered for mission-critical environments where signal integrity and system uptime are non-negotiable, the DS200TCDA-HBHE is the preferred replacement and spare-parts solution for plant engineers maintaining GE Frame 3–9 gas turbines, steam turbines, and combined-cycle units. Konmask.com supplies this board as a genuine OEM-sourced or rigorously tested equivalent, backed by full traceability documentation.

- Proven Reliability: TCDA series boards have accumulated millions of operating hours across global power fleets.
- Reduced Downtime: Stocking this board as a critical spare eliminates multi-week OEM lead times during unplanned outages.
- Traceability: Each unit supplied by Konmask.com includes serialization records and, where available, OEM certification documentation.
System Architecture & Signal Flow
Within the Mark VI architecture, the DS200TCDA-HBHE resides in the I/O terminal board layer, physically located in the I/O cabinet adjacent to the Mark VI controller rack. Field wiring from transmitters, actuators, and sensors terminates directly on the TCDA board’s screw terminals. Signals are conditioned and routed via the I/O ribbon cable or backplane connector to the corresponding Mark VI I/O pack (e.g., VCMI, VAIC, or VAOC packs), which then communicate over the IONet or ARCNET bus to the Mark VI controller (VCCC/VCRC). This architecture ensures deterministic, low-latency analog data acquisition for turbine protection functions including overspeed, exhaust temperature spread, and combustion dynamics monitoring.

Technical FAQ
Q: Is the DS200TCDA-HBHE compatible with Mark VIe systems?
A: The TCDA terminal board series is designed for Mark VI. Mark VIe uses a different I/O architecture (ETD/ETC packs). Cross-compatibility requires engineering review — contact us before ordering.
Q: Can this board be repaired if damaged?
A: Component-level repair is possible for certain failure modes (blown fuses, damaged connectors). Konmask.com can advise on repair vs. replace decisions based on fault description.
Q: What is the typical failure mode for TCDA boards?
A: Most common failures include connector oxidation, blown protection fuses on analog input channels, and capacitor degradation in aging units. All are inspected during our pre-shipment process.
Q: Do you provide MTBF or reliability data?
A: GE’s published Mark VI system MTBF data is available in the Mark VI System Guide (GEH-6421). We can provide this documentation upon request.
Q: Can I order multiple units for a fleet maintenance program?
A: Yes. Volume pricing and consignment stocking arrangements are available. Contact support@konmask.com for a tailored procurement proposal.
