GE DS215UCIBG3AZZ03A UC2000, Controller Card Assembly

الوصف

The GE DS215UCIBG3AZZ03A is a specialized UC2000 Controller Card Assembly used in the GE Mark V Speedtronic series of turbine and generator control systems. It is the core processing unit of the UC2000 control system, providing the computational power and communication interfaces necessary to manage the turbine’s operations.

Function and Purpose

The primary function of the DS215UCIBG3AZZ03A is to serve as a high-performance central processor and communication hub for the Mark V system. Its key roles include:

• Executing Control Logic: The board is equipped with a processor (likely a 486DX4-100) and substantial memory (16 MB of DRAM and 4 MB of flash memory) to run complex control algorithms. These algorithms manage critical turbine operations such as speed, load, and temperature control.
• System Communication: It is a vital communication hub, providing multiple ports for connectivity. This includes two DLAN+ ports, two Genius LAN ports, and two Ethernet ports. This enables the board to communicate with other modules in the Mark V system and with external systems like a plant-wide SCADA (Supervisory Control and Data Acquisition) system.
• Firmware: The board contains on-board software (firmware) that defines its specific functionality. This makes it a self-contained and highly functional unit.
• Fault Tolerance: In a Triple Modular Redundant (TMR) system, three of these boards can be used in the R, S, and T cores. This provides a high degree of fault tolerance, as the system can continue to operate even if one of the boards fails.

Technical and Design Features

The DS215UCIBG3AZZ03A is a robust, industrial-grade circuit board designed for reliability in harsh environments.

• Modular Design: The “DS215” prefix indicates that it is a 2-series board, a later generation of GE’s control cards. The “G3” indicates it is a Group 3 product. It is designed to plug into a VME rack and occupies four VME slots.
• Connectivity: The board features multiple connectors, including those for a keyboard, monitor, and hard disk drive, as well as configuration switches and LED status indicators for on-site diagnostics.
• Supersedes/Replaces: The DS215UCIBG3AZZ03A is an updated version of the UC2000 Module and a part of the DS200UCIBG3 family of boards.
• Power: Power is supplied to the board from the VME connectors.
