Product Description

The GE DS215UDSAG1AZZ01A DS215 Firmware Board is a specialized Printed Circuit Board (PCB) manufactured by General Electric for its highly reliable Mark V Turbine Control System.³ This module is an intelligent component, indicated by the term “Firmware Board,” meaning it houses essential proprietary software code stored on EPROM modules.⁴ Its design suggests a dual role: serving as a microprocessor board for processing control information, and acting as a crucial Human-Machine Interface (HMI) component.⁵ It is populated with an 80196 microprocessor, 21 four-character displays, and 32 LEDs for immediate operational and diagnostic feedback to the operator.⁶ The board receives signals, processes them using its on-board instruction code, and transmits resulting signals to other boards or devices in the drive system.⁷ This module, the GE DS215UDSAG1AZZ01A (Placeholder Link: GE Automation Solutions Product Page), is vital for local control, monitoring, and troubleshooting of compatible gas, steam, and wind turbine automated drive assemblies. The GE DS215UDSAG1AZZ01A (Placeholder Link: GE Automation Solutions Product Page) is often considered a specialized assembly within the DS215 series. The GE DS215UDSAG1AZZ01A (Placeholder Link: GE Automation Solutions Product Page) facilitates crucial operator interaction via its visual indicators and displays.

Product Parameters

As a combined processor and HMI interface, the technical specifications for the GE DS215UDSAG1AZZ01A include:

• Manufacturer/Series: General Electric, Mark V (DS215 Series).⁸
• Microprocessor: Intel 80196 (or equivalent).⁹
• Memory: Several Erasable Programmable Read-Only Memory (EPROM) modules for firmware storage.¹⁰
• Display: 21 four-character displays for alphanumeric information.¹¹
• Indicators: 32 LEDs for diagnostic and status information.¹²

• Coatings: Typically features a normal PCB coating style.¹⁴
• Revision: Features an “A-rated functional product revision.”¹⁵

Advantages and Features

• Integrated Diagnostics: The large number of LEDs and four-character displays provides immediate, local feedback on the drive’s status, error codes (like over-temperature or over-current trips), and activity.¹⁶
• Critical Processing: The on-board microprocessor and firmware execute necessary instruction code to process signals, ensuring timely and correct operation within the excitation or control system.¹⁷
• Specialized Assembly: Designed specifically to meet the unique control and display requirements of the GE Mark V and EX2000 Subseries.
• High Reliability: Built to the robust standards of the GE Speedtronic family for continuous operation in demanding industrial environments.

Application Areas and Use Cases

The GE DS215UDSAG1AZZ01A is indispensable in control systems for:

• Gas and Steam Turbine Excitation Control (EX2000): Provides the necessary processing and operator interface for the excitation system, which controls the voltage of the generator.¹⁸
• Power Generation: Used in control cabinets where the GE Mark V system manages large-scale generators and associated drive assemblies.¹⁹
• Troubleshooting: The integrated displays are a primary resource for maintenance technicians to quickly identify and address trip conditions and operational errors.²⁰

Competitive Comparison

The GE DS215UDSAG1AZZ01A is a specialized module, competing with integrated control/display modules from other high-end legacy systems:

Selection Advice

You should select the GE DS215UDSAG1AZZ01A DS215 Firmware Board when:

1. You are performing maintenance, repair, or replacement on a GE Mark V control system that requires this exact part number for its display, HMI, or processing function.
2. The system relies on the unique diagnostic and display features provided by this board for local operator feedback and troubleshooting (e.g., in the EX2000 excitation system).
3. The continuity of the system’s instruction code and firmware is paramount, requiring a board that can be confirmed to have the correct EPROM modules installed.

Important Considerations

• Firmware Identity: The “ZZ01A” at the end of the part number denotes a specific firmware or assembly variation. It is absolutely critical to ensure the replacement board’s firmware matches the version of the board it is replacing to avoid operational delays or system failure.
• Legacy Status: The Mark V system is considered a legacy platform. Check the latest obsolescence status from GE to plan for long-term sourcing and sparing of the GE DS215UDSAG1AZZ01A (Placeholder Link: GE Automation Solutions Product Page).
• ESD Sensitivity: As a microprocessor-based board with exposed integrated circuits (EPROMs), it must be handled using strict Electrostatic Discharge (ESD) procedures.
