Product Description

The GE DS215UPLAG1AZZ02A LAN Power Supply Board is a proprietary electronic module manufactured by General Electric, designed for insertion into the Mark V Turbine Control System series.² Its primary function, indicated by the ‘UPLA’ acronym, is to provide stable and reliable power supply and interface capabilities for the system’s Local Area Network (LAN) components. This is crucial for maintaining consistent communication and data exchange within the control system rack.

The board is an intelligent component, featuring a microprocessor core, non-volatile memory (Flash/EEPROM) for its firmware, and dedicated communication ports like the DLAN+ interface and an RS-232C serial port.³ The GE DS215UPLAG1AZZ02A (Placeholder Link: GE Automation Solutions Product Page) supplies necessary voltages (such as $24\text{V}$ and $5\text{V}$) to the network communication circuitry. It includes a reset button, two banks of configuration switches, and two indicator LEDs (one green for power, one red for error) for local diagnostics. The GE DS215UPLAG1AZZ02A (Placeholder Link: GE Automation Solutions Product Page) is vital for maintaining network integrity and is an improvement upon earlier DS200 UPLA boards. The GE DS215UPLAG1AZZ02A (Placeholder Link: GE Automation Solutions Product Page is built for industrial durability and reliable power delivery in demanding environments.

Product Parameters

As a combined power supply and communication interface board, the technical specifications include:

• Manufacturer/Series: General Electric, Mark V (DS215 Series), often used in EX2000 Excitation systems.⁴
• Function: LAN Power Supply Circuit / LAN Interface Board.
• Power Output: Switching power supply providing voltages such as ⁵$24\text{V}$ and ⁶$5\text{V}$ to LAN components.⁷
• Microprocessor: Features a dedicated core for handling communication and reset functions.
• Communication Ports: DLAN+ interface port, RS-232C serial port.⁸
• Diagnostics: 1 Green Power-On LED, 1 Red Error/Fault LED.⁹
• Configuration: Includes configuration jumpers and DIP switches for setting operational parameters.¹⁰
• Firmware: Includes on-board memory (EEPROMS/Flash) to store and update firmware (indicated by ZZ02A suffix).

Advantages and Features

• Network Reliability: Ensures stable and clean power delivery specifically to the critical LAN components, preventing communication dropouts due to power fluctuations.
• Integrated Diagnostics: The on-board LEDs and reset button allow technicians to quickly assess the board’s power status and restart processing without completely cycling cabinet power.¹¹
• Custom Integration: Designed with proprietary GE interfaces (like DLAN+) to integrate perfectly into the Mark V backplane, guaranteeing deterministic communication timing.
• Field Configurability: The presence of jumpers and switches allows the board’s operation to be adapted to specific system needs and network topology.¹²

Application Areas and Use Cases

The GE DS215UPLAG1AZZ02A is primarily used in:

• Gas and Steam Turbine Excitation Control (EX2000): Provides essential power and interface functions for the DLAN+ or similar communication network connecting the exciter to the main turbine control.
• Power Generation and Drive Systems: Any application utilizing the GE Mark V series for control of high-value rotating machinery where robust, stable communication is mandatory.
• System Maintenance: Used as a direct replacement part to address intermittent network or power supply issues within the Mark V control rack.

Competitive Comparison

The GE DS215UPLAG1AZZ02A is a proprietary utility module. Its competition lies in the redundant power supply and specialized communication boards of other high-end systems:

Selection Advice

You should select the GE DS215UPLAG1AZZ02A LAN Power Supply Board when:

1. You are maintaining, repairing, or replacing a failed board in a GE Mark V control system that explicitly uses this part number.
2. You are diagnosing communication issues within the control rack’s LAN and suspect the power stability of the network interface.
3. The system requires the specific features and firmware version denoted by the DS215UPLAG1A hardware and ZZ02A firmware suffix.

Important Considerations

• Firmware Match is Crucial: The ZZ02A suffix is vital; it specifies the firmware version. Never install a board with unmatched firmware as it will cause system-wide instability or communication failure.
• Legacy Status: The Mark V platform is a legacy system. Be sure to check the current obsolescence status of the GE DS215UPLAG1AZZ02A (Placeholder Link: GE Automation Solutions Product Page) for long-term planning and ensure a reliable source for spares.
• Power Requirements: When replacing, verify that the incoming power connections to the board are within the specified limits (e.g., $115/230 \text{ VAC}$ or $24 \text{ VDC}$ depending on the variant) before insertion.
