GE Model IS200BPPCH2AEC Data Acquisition Board is a daughterboard for Mark VI to Mark VIe Interfaces produced by General Electric Industrial Systems

الوصف

That is correct. The GE IS200BPPCH2AEC is a highly specific Data Acquisition Board that functions as the processor core for a family of Input/Output ($\text{I/O}$) modules within the General Electric Mark VIe (and sometimes Mark VI to Mark VIe retrofit) Turbine Control Systems.

It is commonly referred to as a “daughterboard” or I/O Pack Processor Card.

⚙️ Function and System Role

The $\text{BPPCH2AEC}$ board is critical because it digitizes field signals and manages network communication for its host I/O module.

• I/O Processing Core: It contains the main local processor ($\text{CPU}$), memory, and data acquisition circuitry. Its primary job is to condition, digitize (using Analog-to-Digital Converters), and process the raw signals received from the connected field devices via the terminal board.
• Network Interface: It provides the communication interface to the main Mark VIe controller via the $\text{IONet}$ (I/O Network), which is a dedicated, high-speed, $100 \text{ Mbps}$ Ethernet link.
• I/O Pack Component: The ¹$\text{BPPCH2AEC}$ is one of three main components that form a complete Mark VIe I/O module:²
  1. Terminal Board (provides field wiring connection points).
  2. Terminal Block (plugs into the terminal board).³
  3. I/O Pack (consisting of the $\text{BPPCH2AEC}$ processor board and a power supply).
• Mark VIe Compatibility: This ⁴$\text{BPPC}$ (Bridge Processor Card C) based architecture is an upgrade from the older ⁵$\text{BPPB}$ models and is typically required for Mark VIe systems running ControlST software version ⁶$\text{V04.04}$ or later.⁷

⚠️ Important Considerations

• Revision Match: The suffix H2AEC is crucial. The $\text{BPPC}$ processor family handles all local processing and network communication; therefore, the replacement board must have an exact revision match to ensure software and network compatibility with the main controller.
• Mark VIeS Exclusion: While the ⁸$\text{BPPC}$ is used in the standard Mark VIe system, different, certified hardware (like the ⁹$\text{UCSE}$ controller) is typically used for the safety-critical Mark VIeS systems.¹⁰
• Application: The $\text{BPPCH2AEC}$ is integrated into various functional $\text{I/O}$ packs, such as $\text{PAIC}$ (Analog Input/Output), $\text{PTCC}$ (Thermocouple Input), and $\text{PAIH}$ (Analog Input). The complete I/O pack number determines the specific field signals it handles.
