Product Description

The GE DS215UPLAG1BZZ01A Power Supply Board is a sophisticated electronic module manufactured by General Electric.¹ Although referred to as a “Power Supply Board,” its primary role is more accurately described as a Power Supply and LAN Interface Board with embedded firmware, designed for the high-reliability GE EX2000 Excitation Control Series (often integrated with Mark V control platforms).²

This board integrates several critical functions: it acts as a switching power supply, converting incoming ³$\text{AC}$ or ⁴$\text{DC}$ power into regulated ⁵$24 \text{ VDC}$ and ⁶$5 \text{ VDC}$ logic power for network components.⁷ It also functions as a LAN Interface, featuring ports like the proprietary DLAN+ interface and an RS-232C serial port for system communication and diagnostics.⁸ The GE DS215UPLAG1BZZ01A (Placeholder Link: GE Automation Solutions Product Page) is an improved version of the earlier DS200UPLAG1A board, integrating a microprocessor core and flash memory for its firmware (denoted by the ‘BZZ01A’ revision). This board GE DS215UPLAG1BZZ01A (Placeholder Link: GE Automation Solutions Product Page is critical for maintaining network communication integrity within the control rack. The presence of a reset button, configuration switches, and diagnostic LEDs ensures local monitoring and management of the GE DS215UPLAG1BZZ01A (Placeholder Link: GE Automation Solutions Product Page.

Product Parameters

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

• Product Type: Power Supply/LAN Interface Board and Firmware.
• Series Compatibility: GE EX2000 Excitation Control System and Mark V Turbine Control.
• Power Input: ⁹$115/230 \text{ VAC}, 50/60 \text{ Hz}$ or equivalent ¹⁰$\text{DC}$ input (depending on exact configuration).¹¹
• Power Output: Regulated ¹²$\text{DC}$ voltages (¹³$\pm 24 \text{ VDC}$ and ¹⁴$5 \text{ VDC}$ switching power supply) for LAN circuitry.¹⁵
• Communication Ports: Dedicated DLAN+ network interface port, RS-232C serial port.¹⁶
• Local Interface: Reset button, 28 jumpers, 2 banks of configuration switches, 1 Green (Power On) LED, 1 Red (Fault) LED, and 1 user-replaceable fuse.¹⁷
• Firmware: Includes on-board memory (EEPROMS/Flash) to store and update firmware (BZZ01A revision).¹⁸

Advantages and Features

• Network Power Stability: Provides isolated and stable power specifically for the critical communication network components (DLAN+), preventing network faults due to fluctuating main power.
• Integrated Communication: Combines power and communication interface functions, streamlining the control rack architecture.
• Local Troubleshooting: The diagnostic LEDs (Green/Red) offer instant visual status, and the reset button allows for localized reboot of the board’s processing without cycling main system power.¹⁹
• Field Configurability: Jumpers and configuration switches allow technicians to customize or tune the board’s operation to specific site requirements and network settings.²⁰

Application Areas and Use Cases

The GE DS215UPLAG1BZZ01A is indispensable in:

• Excitation Control Systems (EX2000): Providing the power and interface for the communication link between the exciter control and the main turbine control system.²¹
• GE Mark V Turbine Controls: Used in the control rack to support network communication components.
• Power Generation: Any GE large-scale rotating machinery application requiring robust, reliable network power and communication management.

Competitive Comparison

The GE DS215UPLAG1BZZ01A competes as a highly specialized proprietary utility module within the dedicated controls market:

Selection Advice

You should select the GE DS215UPLAG1BZZ01A Power Supply Board when:

1. You are performing maintenance, repair, or planned replacement on a GE EX2000 or Mark V system that explicitly requires this part number.
2. You are experiencing intermittent communication issues (e.g., DLAN+ errors) and have traced the problem to the LAN power/interface module.
3. The system integrity demands the specific hardware and firmware revision (DS215UPLAG1B hardware and ZZ01A firmware) for validated operation.

Important Considerations

• Firmware Match: The BZZ01A suffix is critical; you must match the exact firmware version when replacing the board to ensure compatibility with all other modules in the control rack.
• Legacy Status: The Mark V and EX2000 platforms are legacy systems. Verify the current obsolescence status of the GE DS215UPLAG1BZZ01A (Placeholder Link: GE Automation Solutions Product Page) and plan for long-term sparing or potential future system upgrades.
• Handling: Due to its sensitive power supply and microprocessor circuitry, the board must be handled using strict Electrostatic Discharge (ESD) precautions.
