GE DS200UCPBG6ADA IO Engine CPU Board

الوصف

The GE DS200UCPBG6ADA is an I/O Engine CPU Board (Input/Output Engine Central Processing Unit Board) for the General Electric Speedtronic Mark V Gas and Steam Turbine Control System.

This board is a critical component that manages the flow of field data (inputs and outputs) for the main turbine control processors.

⚙️ Function and Role in the Mark V System

The primary function of the DS200UCPBG6ADA (UCPB) is to serve as a dedicated I/O processor that works in conjunction with other boards within the Mark V control panel’s I/O Engines ($\text{R1}$, $\text{R2}$, $\text{R3}$, etc.).

• I/O Data Handler: The board handles the local processing, packaging, and transmission of input/output data from the various termination boards and I/O cards (like $\text{Analog}$ or $\text{Discrete}$) that connect directly to the turbine’s sensors and actuators.
• Decentralized Processing: By distributing the I/O processing tasks, the UCPB offloads this work from the main, Triple Modular Redundant ($\text{TMR}$) control processors ($\text{R, S, T}$), allowing them to focus solely on the critical control and protection algorithms.
• Communication: It contains an ARCNET driver to communicate the I/O data packets over the high-speed COREBUS network to the $\text{R, S, and T}$ controllers, which then use this data to execute the control logic (including two-out-of-three voting).
• Hardware and Memory: The board typically includes a 486DX microprocessor and uses SIMM sockets for memory (¹$\text{DRAM}$ and ²$\text{EPROM}$) to store firmware and I/O configuration data.³

In essence, it acts as the intelligent interface that translates the physical state of the turbine into the digital information required by the primary control system.
