The GE DS215SCMAG1AA is a critical, highly specialized printed circuit board assembly used in General Electric’s industrial control systems, specifically the Speedtronic Mark V Turbine Control System.
It is formally known as a Programmable Coprocessor Module (PCM), and its function is vital for managing complex, non-core control tasks within the system.
⚙️ Key Specifications and Function
| Feature | Specification/Description |
| Product Type | System Control Main Assembly (SCMA) / Programmable Coprocessor |
| Series/Family | GE Speedtronic Mark V Turbine Control Systems and Associated Drives |
| Core Function | Auxiliary Processor/Data Handler. It acts as a coprocessor to the main turbine control processors (the UCOM R, S, T boards). Its main role is to offload and execute complex, specialized tasks, such as: * Data Acquisition & Logging: Handling high-volume data from I/O channels for fault logging and diagnostics. * Communication: Managing specialized industrial communication protocols. * Real-Time Computations: Executing sophisticated calculations that would otherwise burden the main TMR (Triple Modular Redundancy) processors. |
| Architecture | It is a complex printed circuit board designed to be installed in a dedicated slot within the VME rack of the Mark V system. Note: Some versions of this board are large and may require two adjacent VME rack slots due to their size. |
| Diagnostics | The board includes an array of LED indicators (often a bank of 10) that can display fault codes in a binary or BCD pattern (Slow, Fast, or Intermittent blinks), providing crucial diagnostic information to technicians. |
| Configuration | Features multiple wire and berg-type jumpers that must be correctly configured based on the application and system setup before installation. |
| Revision Level | The G1AA specifies the Group 1 hardware revision, with two A-rated functional product revisions. |
In essence, the DS215SCMAG1AA Programmable Coprocessor increases the overall processing power and efficiency of the Mark V system by dedicating a high-performance module to handle secondary, yet critical, computational and interface tasks.
