Overview Manuals Specifications Application Performance & Efficiency Application Scenarios

Features:

  • Certified to IEC 61508 for functional safety, capable of handling critical turbine protection tasks such as emergency shutdowns (ESD) and overspeed detection .
  • Flexible Redundancy (TMR/Duplex): Supports Triple Modular Redundancy (TMR) and duplex configurations, allowing for hot-repair of modules without shutting down the turbine and eliminating single points of failure.
  • Features a wide operating temperature range (-40°C to +70°C), replaceable fuses, test points (TPs), and LED status indicators for easy in-situ maintenance.
In a gas turbine application, the consequences of a processor failure can be catastrophic, ranging from overspeed rotor bursts to unplanned blackouts. The DS200UPSAG1A is specifically engineered and certified to IEC 61508 for Safety Integrity Level (SIL) 2 and SIL 3 applications . This means it has a proven, extremely low probability of dangerous failure.

Industrial facilities cannot afford costly downtime every time a hardware component requires maintenance. The DS200UPSAG1A resolves this risk by supporting multiple redundancy architectures. In a Triple Modular Redundancy (TMR) setup, the system uses three DS200UPSAG1A modules voting on the output . If one module outputs a faulty calculation or fails completely, the other two healthy modules outvote it, allowing the turbine to continue operating safely.

The DS200UPSAG1A is built to survive the extreme conditions of a power plant environment. It reliably operates in ambient temperatures ranging from -40°C to +70°C, ensuring stable performance in unheated turbine halls or outdoor enclosures . For field diagnostics, the board includes 3 user-replaceable fuses that protect critical circuits from overcurrent, a physical reset button for recovery, and a clear LED power indicator .

The DS200UPSAG1A General Electric Power Supply Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL)by the manufacturer (OEM).

Description
The DS200UPSAG1A is a Power Supply Board belonging to the GE Mark VIe series, designed for safety control in distributed control systems (DCS) . It is equipped with a 1.6GHz AMD G-Series dual-core microprocessor, 2GB of DDR3 SDRAM, and 128GB of storage, running the QNX Neutrino real-time operating system (RTOS) for high-reliability tasks .

When using the DS200UPSAG1A, engineers can configure it for simplex, duplex, or Triple Modular Redundancy (TMR) to achieve various levels of system availability . It supports SIL 2 and SIL 3 safety levels, complying with the IEC 61508 functional safety standard, which is essential for applications such as gas and steam turbine control.

The DS200UPSAG1A integrates seamlessly with the Mark VIe ecosystem using the ToolboxST software for configuration, which requires Control ST V07.02 or higher . It features a wide input voltage range of 18-32VDC and operates in temperatures from -40°C to +70°C, ensuring reliable function in harsh industrial environments.

For legacy system maintenance or upgrades, the DS200UPSAG1A is listed as "in-service," ensuring long-term technical support . Its robust design and high MTBF (Mean Time Between Failures) of up to 414,248 hours make it a reliable choice for continuous operation.

Technical notes
The DS200UPSAG1A has two distinct identities in the field: It is commonly sold as a Mark V Power Supply Board but is also listed as a Mark VIe Dual-Core Safety Controller . This suggests the base part number may have been used across generations, or the board serves as a power interface for newer controllers.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Does this module have the necessary SIL 3 certification for gas turbine emergency shutdown applications?
Yes. The DS200UPSAG1A is certified to IEC 61508 SIL 3 for high‑integrity safety functions. Its QNX real‑time operating system deterministically executes critical safety tasks such as overspeed detection and flame monitoring, meeting turbine control safety requirements.
How can I avoid an unplanned turbine shutdown if a single module fails?
The DS200UPSAG1A supports TMR (Triple Modular Redundancy) and dual‑unit configurations. In TMR mode, three modules vote (2oo3). If one module fails or produces an error, the other two override it, allowing the turbine to continue safe operation while the failed unit is replaced online.
Without programming software onsite, how can I quickly determine if the module is faulty?
The module has a green power status LED. If the LED is off, first check the three user‑replaceable fuses. Then measure voltages at the test points (TPs) with a multimeter. If 28V DC input is present but output voltages are missing, the module is likely defective.
Which software is required to program and configure this module?
You must use GE’s ToolboxST software (Control ST version V07.02 or higher). ToolboxST allows you to configure redundancy mode (simplex, dual, TMR), develop safety logic, and download it to the DS200UPSAG1A. Older software versions may not recognize this module.
