GE DS215UCIBG3AZZ01A UC2000, Controller Card Assembly

الوصف

The GE DS215UCIBG3AZZ01A is a specialized UC2000 Controller Card Assembly used in the GE Mark V Speedtronic series of turbine control systems. This board is a central processing unit that provides the computational power and communication interface to control the turbine. It is also known as a WIN System Card.

Function and Purpose

The primary function of the DS215UCIBG3AZZ01A is to serve as a 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 memory (16 MB of DRAM and 4 MB of flash memory) to run complex control algorithms that manage critical turbine operations, such as speed, load, and temperature control.
• System Communication: It is a vital communication hub, providing various ports for connectivity, including 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 DS215UCIBG3AZZ01A 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: It is an updated version of the UC2000 Module and a part of the DS200UCIBG3AAA family of boards.
• Power: Power is supplied to the board from the VME connectors.
