Product Overview
In GE Mark V turbine control systems, stable and reliable power distribution is essential for maintaining the operation of processors, I/O hardware, communication circuits, and other control-system components. The GE DS200UPSAG1AGD MARK V Power Board is a dedicated power-related board designed for use within this industrial control architecture.
The DS200UPSAG1AGD belongs to the GE DS200 family and is identified as a Mark V Power Board. Its primary role is associated with power distribution, conditioning, and electrical support for connected control-system circuitry.
Unlike a processor board, the DS200UPSAG1AGD is not primarily responsible for executing turbine-control logic. It instead provides an important electrical infrastructure function that allows associated Mark V hardware to receive the required power.
The board can operate as part of a larger Mark V cabinet together with control processors, I/O boards, communication modules, terminal boards, and other power-related components.
The specified dimensions of the DS200UPSAG1AGD are 200 × 150 × 25 mm, with a specified weight of 0.93 kg.

Function and Working Principle
The main function of the DS200UPSAG1AGD is to provide power-related support within the Mark V control architecture.
A turbine control system contains numerous electronic circuits that require stable electrical power. Processor boards, I/O modules, communication interfaces, and other control hardware depend on appropriate power distribution to operate correctly.
The general power relationship can be represented as:
System Power Source → DS200UPSAG1AGD → Mark V Control Circuits → Processor / I/O / Communication Hardware
The board participates in the electrical power path and helps provide the required power interface for associated circuitry.
Depending on the system configuration, power-related functions can support:
- Control processors
- I/O engines
- Communication hardware
- Digital I/O modules
- Analog I/O modules
- Interface boards
- Control cabinet circuitry
- Auxiliary control equipment
A power-board failure can therefore have effects beyond the board itself. Loss of a required supply can cause downstream control hardware to shut down, reset, generate diagnostic alarms, or lose communication.
For this reason, power-related troubleshooting should consider the complete electrical path rather than examining the board in isolation.
Role in Industrial Control Systems
The DS200UPSAG1AGD plays a supporting role in the power architecture of GE Mark V turbine control systems.
The Mark V architecture contains multiple specialized hardware groups. CPU boards process control algorithms, I/O boards acquire and generate field signals, communication boards exchange information, and power boards provide the electrical infrastructure required by these components.
The DS200UPSAG1AGD belongs to the power-support portion of this architecture.
It can work alongside:
- Mark V control processors
- I/O engine CPU boards
- Digital I/O boards
- Analog I/O boards
- LAN communication hardware
- Terminal boards
- Power input boards
- Auxiliary power circuits
- Control cabinet distribution hardware
Its role is especially important in legacy turbine systems where the original power architecture must remain compatible with the existing control hardware.
Industrial Applications
The GE DS200UPSAG1AGD is primarily associated with GE Mark V turbine automation systems.
Typical applications include:
- Gas turbine control
- Steam turbine control
- Combined-cycle power plants
- Turbine generator systems
- Industrial turbine packages
- Mechanical-drive turbines
- Compressor-drive turbine systems
- Power-generation automation
- Turbine control cabinets
- Legacy GE Speedtronic installations
In these environments, reliable power distribution is necessary for maintaining stable operation of the complete control system.
The DS200UPSAG1AGD can therefore serve as an important supporting component in systems where multiple Mark V boards depend on the same power architecture.
Installation and System Integration
Correct installation is essential because the DS200UPSAG1AGD is associated with the electrical power system of the control cabinet.
Before replacing the board, technicians should document the original installation and verify the electrical characteristics of the replacement.
Recommended procedures include:
- Follow the approved turbine shutdown procedure.
- Isolate the appropriate control-system power.
- Verify the complete DS200UPSAG1AGD part number.
- Record the board revision.
- Document all cables and connector positions.
- Identify the original cabinet location.
- Inspect the replacement board for physical damage.
- Check connectors and power-related components.
- Compare the replacement with the original board.
- Install the board in the designated Mark V position.
- Reconnect wiring according to approved documentation.
- Verify associated power-input and power-output connections.
- Check downstream power circuits.
- Restore power according to approved procedures.
- Verify power-system indications.
- Check Mark V diagnostic information.
- Confirm operation of connected control hardware.
- Verify communication and I/O functionality.
- Perform system-level testing before returning equipment to service.
ESD protection should be used whenever handling the PCB.
Power-related boards should never be substituted solely according to physical dimensions. The electrical characteristics, connector configuration, revision, and system application must be checked before installation.
