GE DS200TBQDG1AFF – RST Termination Relay Board | Mark VI Control Platform
Engineering Background
The DS200TBQDG1AFF is a factory-original termination relay board engineered by General Electric as an integral signal-conditioning and relay-interface component within the Mark VI Turbine Control System. Designed for gas turbine, steam turbine, and combined-cycle power generation applications, this board serves as the hardwired bridge between field I/O wiring and the Mark VI controller backplane — ensuring deterministic signal integrity in safety-critical environments.
Product Positioning
Procurement engineers sourcing DS200TBQDG1AFF face a narrow market of genuine, traceable units. Konmask.com specialises in verified GE Mark VI spare parts, offering documented provenance, pre-shipment inspection, and direct technical support — eliminating the risk of counterfeit or refurbished-without-disclosure components entering your control system.

Engineering Advantages
- OEM-Matched Signal Integrity — Relay contact ratings and PCB trace geometry matched to GE Mark VI I/O specifications; no de-rating or field modification required.
- Plug-and-Play Replacement — Direct form-fit-function replacement for failed or degraded DS200TBQDG1AFF boards; zero firmware changes needed.
- Relay Isolation — Galvanic isolation between field wiring and controller backplane protects against ground loops and transient surges common in turbine environments.
- Reduced MTTR — Stocking a spare DS200TBQDG1AFF reduces mean time to repair from days (OEM lead time) to hours (on-shelf swap).
- Broad Compatibility — Compatible across Mark VI VCMI, VCRC, and VTUR controller configurations without hardware modification.
System Architecture & Signal Flow
Within the Mark VI architecture, the DS200TBQDG1AFF occupies the termination layer between field devices and the I/O processor boards. Field wiring (discrete outputs from actuators, solenoids, and trip circuits) lands on the terminal block side of the board. The relay contacts switch these field-side signals under command from the Mark VI I/O processor, while the PCB provides the necessary voltage clamping, flyback suppression, and contact status feedback to the controller. This architecture ensures that field-side faults are isolated from the controller backplane, maintaining system availability during partial fault conditions.

Technical FAQ
Q: Is DS200TBQDG1AFF compatible with Mark VIe?
A: The DS200TBQDG1AFF is designed for the Mark VI platform. Compatibility with Mark VIe depends on the specific I/O module configuration — contact our engineers with your panel drawing for confirmation before ordering.
Q: What is the difference between DS200TBQDG1AFF and DS200TBQDG1AFE?
A: The suffix revision letter (F vs E) denotes a GE engineering change level. Functionally these are typically interchangeable, but always verify against your system BOM. Our team can cross-reference your panel documentation.
Q: Can you provide a datasheet?
A: GE Mark VI component datasheets are controlled documents. We can share available technical references under NDA or provide our internal inspection report as a substitute for procurement qualification.
Q: What is the lead time?
A: In-stock units ship within 3–5 business days internationally. If not in stock, typical sourcing lead time is 2–4 weeks depending on market availability.
Q: Do you accept returns?
A: Yes. DOA (dead on arrival) returns accepted within 14 days of receipt. Tested units carry a 90-day warranty against manufacturing defects.
