GE DS215UPLAG1BZZ01A

Product Overview

The GE DS215UPLAG1BZZ01A is a UPLAG1 power supply and LAN interface board associated with GE Mark V / EX2000 excitation control systems. It is an upgraded version of the DS200UPLAG1A and incorporates onboard EEPROM firmware for the applicable control configuration.

The board combines power-conversion, processor, memory, and communication functions in one assembly. It is intended for industrial turbine and excitation-control environments where dependable power and control-system communication are essential.

Key Technical Information

The main product characteristics are:

• Manufacturer: General Electric
• Model: DS215UPLAG1BZZ01A
• Product Family: GE Mark V / EX2000
• Functional Designation: UPLA / UPLAG1
• Product Type: Power Supply and LAN Interface Board
• Functional Revision: B
• Additional Revision: Z
• PCB Coating: Normal coating
• Firmware: Integrated EEPROM firmware
• Mounting: VME rack installation
• Communication: DLAN+ interface and RS-232C serial interface
• Power Conversion: Supports the associated Mark V control-system power architecture

The exact electrical configuration should always be confirmed against the original system documentation and board identification before replacement.

Internal Architecture and Hardware

The DS215UPLAG1BZZ01A is more than a conventional power-supply card. Its hardware includes a microprocessor core, Flash/non-volatile memory capability, power-on reset circuitry, 5 V undervoltage detection, DLAN+ interface, and RS-232C serial communication interface.

The board also contains several field-service and diagnostic elements:

• One reset pushbutton
• 28 jumpers
• Two banks of configuration switches
• One green power-status LED
• One red fault LED
• One fuse identified as FU1
• Supporting transistors, capacitors, resistors, diodes, and integrated circuits

The green LED provides an indication that board power is present, while the red LED is used as a fault indication. The reset function allows the board’s processing operation to be restarted without removing system power.

Functions Within Mark V and EX2000 Systems

The DS215UPLAG1BZZ01A plays a combined role in the control architecture. Its power-supply circuitry supports the required control electronics, while its communication interfaces allow data exchange with associated equipment.

The board is associated with GE EX2000 excitation control systems, which are used in generator excitation and power-generation applications. It is also cataloged within the broader GE Mark V DS200/DS215 turbine-control product family.

Its communication and processing capabilities make it relevant to systems where controller-to-device data exchange and reliable internal power are required.

Application Areas

Typical applications for the GE DS215UPLAG1BZZ01A include:

• GE EX2000 excitation control systems
• Generator excitation equipment
• Mark V turbine control installations
• Industrial power-generation plants
• Steam and gas turbine control environments
• Turbine control system maintenance
• Legacy GE Speedtronic system modernization

For older installations, retaining a compatible spare board can be particularly useful because a failure of a power or communication-related PCB may affect multiple functions within the control system.

Installation, Diagnostics and Replacement

Before installing the DS215UPLAG1BZZ01A, technicians should verify the complete part number, functional revision, firmware configuration, jumper positions, switch settings, and communication connections against the existing board.

During troubleshooting, the FU1 fuse should be inspected first when a power-related fault is suspected. However, replacing a blown fuse alone may not resolve the problem if an underlying component fault remains.

The board should be handled using suitable ESD precautions, and the associated control cabinet should be de-energized according to the plant’s approved maintenance procedures before physical replacement.

When sourcing a replacement, matching DS215UPLAG1BZZ01A rather than relying only on a similar DS200/DS215 model is recommended. Revision and firmware differences can affect system compatibility. Correct identification helps reduce commissioning time and supports reliable maintenance of legacy GE turbine and excitation-control equipment.
