General Electric DS200TCQAG1BHF – RST Analog I/O Board | Mark V LCI Turbine Control Platform
Engineering Background
The DS200TCQAG1BHF is a factory-original analog input/output board engineered by General Electric for deployment within the Mark V LCI (Load Commutated Inverter) turbine control architecture. Designed to interface directly with GE’s proprietary backplane and signal conditioning infrastructure, this board serves as the primary analog signal gateway between field instrumentation and the Mark V control processor.
Product Positioning
Targeted at maintenance engineers and procurement specialists managing legacy GE Mark V turbine control systems in power generation, oil & gas, and heavy industrial facilities. The DS200TCQAG1BHF is a direct OEM replacement that eliminates the risk of signal drift, calibration mismatch, or compatibility failures associated with third-party alternatives. Konmask.com supplies verified surplus units with full traceability documentation.

- Traceability: Each unit ships with inspection records and sourcing documentation for audit compliance
System Architecture & Signal Flow
Within the Mark V LCI architecture, the DS200TCQAG1BHF occupies the RST (Rotor Speed/Temperature) analog I/O slot. It conditions raw analog signals from field sensors — including speed pickups, thermocouple inputs, and process transmitters — and routes conditioned data to the Mark V TCCA/TCDA processor cards via the internal VME-style backplane. Output channels drive actuator reference signals and analog feedback loops for closed-loop turbine speed and load control.
Signal flow: Field Sensor → DS200TCQAG1BHF (A/D conversion & conditioning) → Mark V Backplane → TCCA Processor → Control Output → Actuator
Sourcing & Quality Verification
- All units sourced from decommissioned OEM installations or authorized surplus channels
- Pre-shipment inspection: visual, functional continuity, and component-level checks
- Anti-static packaging with humidity indicator cards for safe international transit
- Batch traceability records available upon request for regulated industries
- Cross-referenced against GE BOM and revision history to confirm hardware revision compatibility
Procurement Process
- Confirm compatibility: Verify your Mark V LCI panel revision and slot assignment against DS200TCQAG1BHF hardware revision suffix (G1BHF)
- Request a quote: Contact [email protected] for volume pricing, lead time confirmation, and export documentation
- Order & payment: T/T wire transfer, PayPal, or trade credit (approved accounts)
- Shipment: DHL / FedEx international express with full customs documentation (commercial invoice, packing list, COO)
- Incoming inspection: Konmask recommends bench-testing the board against a known-good Mark V LCI chassis before installation
Technical FAQ
Q: Is the DS200TCQAG1BHF interchangeable with DS200TCQAG1A or other suffix variants?
A: Hardware revision suffixes indicate PCB and component-level changes. While many suffix variants are functionally compatible, Konmask recommends confirming the exact revision required by your Mark V LCI panel BOM before ordering. Contact our engineering team for cross-reference support.
Q: Can this board be used in Mark VI or Mark VIe systems?
A: No. The DS200TCQAG1BHF is designed exclusively for the Mark V LCI platform. Mark VI and Mark VIe use a different I/O architecture (IONET-based) and are not backward compatible with Mark V analog boards.
Q: Do you provide a test report with the unit?
A: Yes. A pre-shipment inspection checklist is included with every unit. Full functional test reports are available for an additional fee — contact us to arrange.
Q: What is the lead time for multiple units?
A: Single units ship within 3–5 business days. For orders of 3+ units, contact us for stock confirmation and consolidated shipping options.
Q: Can Konmask assist with installation or commissioning?
A: Konmask provides remote technical guidance for board installation and initial power-up verification. On-site commissioning support is available through our partner network — inquire at [email protected].
