Product Overview
The GE DS200TCTGG1AEE MARK V Relay Board is a specialized relay interface board designed for GE Mark V Speedtronic turbine control systems. As part of the DS200 family, it provides discrete relay-based signal switching and interface functions between the turbine control architecture and associated field circuits.
Relay boards are important in turbine automation because the control system must exchange discrete commands and status signals with many external devices. These can include solenoids, alarm circuits, interlocks, auxiliary equipment, and turbine protection-related circuits.
The DS200TCTGG1AEE is designed to operate as part of the Mark V control architecture rather than as a standalone controller. Its relay circuits provide an electrical interface for discrete control signals generated or processed by the larger turbine control system.
The specified dimensions of the DS200TCTGG1AEE are 210 × 150 × 35 mm, with a specified weight of 0.8 kg.

Function and Working Principle
The main function of the DS200TCTGG1AEE is to provide relay-based switching and interface capability within the Mark V turbine control system.
The Mark V control architecture processes turbine operating information and generates control commands. When a discrete output is required, the corresponding control signal can be routed through the appropriate interface circuitry and relay contacts.
A simplified signal path can be represented as:
Mark V Control Logic → I/O Interface → DS200TCTGG1AEE → Relay Circuit → Terminal Interface → External Device
The relay changes state according to the control signal received from the turbine control system. This allows the board to provide discrete electrical switching for connected circuits.
Depending on the turbine configuration, relay outputs can be associated with:
- Solenoid commands
- Alarm signals
- Equipment status
- Interlock conditions
- Permissive signals
- Auxiliary equipment
- Turbine operating commands
- Discrete status transmission
- Protection-related interfaces
The precise assignment of individual relay circuits depends on the turbine-specific wiring and Mark V system configuration.
Role in Industrial Control Systems
The DS200TCTGG1AEE performs an important interface function within the GE Mark V turbine automation architecture.
A turbine control system contains multiple levels of hardware. Processors execute control algorithms, I/O hardware handles field signals, terminal boards provide wiring interfaces, and relay boards provide electrical switching for discrete circuits.
The DS200TCTGG1AEE can therefore act as an intermediate interface between control-system electronics and external equipment.
It may operate alongside:
- Mark V control processor boards
- Digital I/O boards
- Terminal boards
- Relay interface modules
- Turbine protection hardware
- Solenoid circuits
- Alarm systems
- Interlock circuits
- Auxiliary equipment
- Turbine control cabinets
Its role is particularly useful when a control command needs to be transferred from electronic control logic into a conventional discrete electrical circuit.
Industrial Applications
The GE DS200TCTGG1AEE is associated with GE Mark V Speedtronic turbine control systems and can be used in various turbine automation environments.
Typical applications include:
- Gas turbine control
- Steam turbine control
- Combined-cycle power generation
- Turbine generator systems
- Industrial turbine packages
- Mechanical-drive turbine systems
- Compressor-drive turbines
- Power-generation automation
- Turbine auxiliary control
- Discrete alarm systems
- Equipment interlocking
- Legacy GE Speedtronic installations
In these systems, relay interfaces are useful for connecting control logic to devices that operate through discrete electrical signals.
For example, a relay circuit can be used as part of an auxiliary equipment command, alarm indication, solenoid interface, or interlock circuit.
Installation and System Integration
Correct installation is essential when replacing or installing a DS200TCTGG1AEE because the board forms part of the turbine’s electrical control system.
Before removing an existing board, technicians should document the complete wiring configuration and connector locations.
Recommended installation procedures include:
- Follow the approved turbine shutdown procedure.
- Isolate the appropriate control-system power.
- Verify the complete DS200TCTGG1AEE part number.
- Record the board revision.
- Document all cable and connector positions.
- Compare the replacement board with the original.
- Inspect the PCB for visible damage.
- Check connectors and relay components.
- Install the board in the correct Mark V cabinet position.
- Reconnect cables according to the original configuration.
- Verify terminal-board wiring.
- Check all associated discrete circuits.
- Restore power according to approved procedures.
- Check system diagnostics.
- Verify relay operation.
- Confirm expected field-device responses.
- Perform functional testing before returning the equipment to service.
Appropriate ESD protection should be used when handling the board.
Because relay outputs can directly affect external equipment, technicians should verify the complete signal path rather than relying only on connector position or physical appearance.
Compatible System Components
The DS200TCTGG1AEE normally operates together with other components in the Mark V turbine control system.
| Component | Function |
|---|---|
| Mark V Control Processor | Executes turbine-control logic |
| Digital I/O Boards | Process discrete control and status signals |
| Terminal Boards | Provide field wiring interfaces |
| Relay Interface Hardware | Supports discrete switching functions |
| Solenoid Devices | Receive discrete control commands |
| Alarm Circuits | Provide equipment and system status |
| Interlock Circuits | Implement permissive and control conditions |
| Protection Hardware | Supports turbine protection functions |
| Auxiliary Equipment | Receives discrete control commands |
| Control Cabinet | Houses Mark V control hardware |
The exact system components connected to the DS200TCTGG1AEE depend on the specific turbine configuration.
Recommended Alternative Models
The following models may be considered when evaluating related GE Mark V relay and turbine-control hardware:
| Model | Type | Key Feature | Application |
|---|---|---|---|
| DS200TCTGG1AEE | Relay Board | TCTG relay interface | Mark V discrete control |
| DS200TCTGG1A | Relay Board | Related TCTG architecture | Turbine control |
| DS200TCTEG1ABA | TC2000 Trip Module | Dedicated trip interface | Turbine protection |
| DS200TCRAG1ACC | Relay Output Board | Multiple relay outputs | Mark V discrete output |

These models are related to GE Mark V control and relay-interface applications, but they should not automatically be treated as direct replacements.
Different board families can have different signal assignments, relay functions, connector layouts, and system applications. Compatibility should therefore be confirmed using the complete original part number and turbine-specific configuration.
