GE DS200RTBAG2A – Relay Terminal Board | Mark VI Turbine Control Platform
Engineering Background: The DS200RTBAG2A is a relay terminal board engineered by General Electric as a core I/O interface component within the Mark VI turbine control system — GE’s flagship distributed control architecture for gas turbines, steam turbines, and combined-cycle power generation units. Designed to operate in demanding industrial environments, this board provides the critical relay switching and signal termination functions that bridge the Mark VI controller with field-level actuators, solenoids, and protective relay circuits.
Product Positioning: Konmask.com supplies the DS200RTBAG2A to maintenance engineers, OEM integrators, and plant operations teams requiring a verified, drop-in replacement or spare-parts inventory solution. Each unit is sourced through controlled supply channels and undergoes functional verification prior to dispatch.

Engineering Advantages
- Direct Compatibility: Plug-and-play replacement within existing Mark VI racks — no firmware modification required for standard relay terminal board positions.
- Relay Isolation: Provides galvanic isolation between the controller logic layer and field-side actuator circuits, protecting sensitive Mark VI processor boards from voltage transients.
- High Signal Integrity: Screw-terminal design ensures low-resistance, vibration-resistant field wiring connections critical in turbine environments.
- Reduced Downtime: Stocking a verified DS200RTBAG2A spare eliminates extended lead times during unplanned outages — a key risk mitigation strategy for power generation assets.
- Tested Before Dispatch: All units supplied by Konmask.com are functionally verified against GE Mark VI relay board test criteria.
System Architecture & Signal Flow
Within the Mark VI architecture, the DS200RTBAG2A sits at the I/O termination layer. The signal flow is as follows:
- Controller Output: The Mark VI VCMI or VCRC controller card generates discrete output commands.
- Relay Actuation: The DS200RTBAG2A relay coils receive the low-voltage logic signal and switch the corresponding dry-contact relay outputs.
- Field Device Interface: The switched relay contacts connect to field-side solenoid valves, motor starters, alarm annunciators, or protective relay trip coils via the screw-terminal block.
- Feedback Loop: Contact status can be monitored by the Mark VI system for diagnostic and alarm purposes, supporting TMR (Triple Modular Redundancy) voting logic where applicable.
Sourcing & Quality Verification
- Supply Chain: Units are sourced from decommissioned plant inventories, authorized surplus channels, and OEM-certified distributors — never from unverified grey-market sources.
- Inspection Protocol: Visual inspection for PCB damage, relay contact wear, and terminal block integrity; functional relay switching test under rated coil voltage.
- Traceability: Each unit ships with a Konmask inspection record including source documentation and test date.
- Packaging: Anti-static ESD bag + foam-lined carton; humidity indicator card included for long-distance shipments.
- Warranty: 12-month limited warranty against manufacturing defects and functional failure under normal operating conditions.

Technical FAQ
Q: Is the DS200RTBAG2A compatible with Mark VIe systems?
A: The DS200RTBAG2A is designed for the Mark VI platform. Compatibility with Mark VIe depends on the specific rack configuration and I/O module mapping. Contact our engineering team with your system drawing for confirmation before ordering.
Q: Can this board be used as a direct replacement without reconfiguration?
A: In most standard Mark VI relay terminal board positions, yes — the DS200RTBAG2A is a drop-in replacement. However, always verify the board revision and terminal assignment against your site-specific Mark VI configuration documentation.
Q: What is the typical lead time for in-stock units?
A: In-stock units ship within 2–5 business days. For units requiring sourcing, lead time is typically 2–4 weeks. Contact us for real-time stock status.
Q: Do you provide a test report with the unit?
A: Yes. A Konmask functional test record is included with every shipment, documenting relay switching performance and visual inspection results.
Q: Can you supply multiple units for a plant-wide spare parts program?
A: Yes. Konmask supports bulk procurement and long-term supply agreements for power generation and industrial automation facilities. Contact us for volume pricing.
