GE DS200UCIBG3AAB UC2000 Motherboard

د.إ8,888.00

The DS200UCIBG3AAB acts as the backplane and interface for the core control engine, providing the communication bus and physical connections for several daughterboards:

  • CPU Board (e.g., LBC586P): This is the slot where the main processor board plugs in. The CPU executes the turbine’s control logic, sequencing, and application software.
  • TMR Communication Board (PANA): The PANA board, which handles the high-speed ARCNET communication, connects through the UCIB. This is critical for the Mark V’s Triple Modular Redundancy (TMR), allowing the three control cores to synchronize and vote on control signals for fault tolerance.
  • I/O Adapter Boards ($\mu$GENI): It provides connectors for the Genius I/O adapter boards, which manage communications with field devices.

الوصف

The GE DS200UCIBG3AAB is a UC2000 Motherboard (UCIB) and is a foundational component of the General Electric Mark V Speedtronic Turbine Control System.

This board is the central wiring and connection point for the main control processing unit within one of the three redundant control cores (T, R, or S). The long number indicates a specific revision of the hardware.

🏗️ Role in the Control System

The DS200UCIBG3AAB acts as the backplane and interface for the core control engine, providing the communication bus and physical connections for several daughterboards:

  • CPU Board (e.g., LBC586P): This is the slot where the main processor board plugs in. The CPU executes the turbine’s control logic, sequencing, and application software.
  • TMR Communication Board (PANA): The PANA board, which handles the high-speed ARCNET communication, connects through the UCIB. This is critical for the Mark V’s Triple Modular Redundancy (TMR), allowing the three control cores to synchronize and vote on control signals for fault tolerance.
  • I/O Adapter Boards ($\mu$GENI): It provides connectors for the Genius I/O adapter boards, which manage communications with field devices.

Onboard Intelligence

The UCIB board itself contains an onboard 80196 microprocessor. This dedicated processor performs time-critical, front-end tasks, such as:

  • Signal Conditioning: It translates and conditions high-resolution pressure transducer signals coming from the TCSA (Fuel Skid Interface) board, a function particularly important for turbines utilizing Dry Low Emissions (DLE) technology.
  • Firmware Storage: The UCIB has slots for PROM modules (Programmable Read-Only Memory) or, in some later revisions, small integrated solid-state storage that hold the firmware and programming instructions for the onboard microprocessor.

🏷️ Part Number Breakdown

The full part number details the board’s series, function, group, and revision level:

Segment Detail Meaning
DS200 Series GE Mark V Speedtronic Control System.
UCIB Functional Acronym UC2000 Core Mother Board.
G3 Grouping Group 3 variant of the Mark V hardware, indicating a specific generation or application type.
AAB Revisions This board has a first functional revision (A) and two subsequent production/artwork revisions (A and B), meaning it’s a very specific, later iteration of the Group 3 hardware.

In essence, the DS200UCIBG3AAB is the sophisticated chassis that holds the brain and nervous system of a single, redundant control core within a GE turbine system.
