The GE DS215LRPBG1AZZ02A is a critical, high-integration printed circuit board assembly used in General Electric’s industrial control systems.1
It is definitively identified as a Resolver Card used in the GE Speedtronic Mark V Turbine Control System and associated high-reliability drives.2
⚙️ Key Specifications and Function
| Feature | Specification/Description |
| Product Type | Line Rectifier Protection Board (LRPB) / Resolver Card |
| Series/Family | GE Speedtronic Mark V Turbine Control Systems |
| Core Function | Position and Speed Feedback. It is an interface board that performs the critical task of translating analog sine and cosine signals received from a resolver (an electro-mechanical sensor on the turbine/motor shaft) into digital position and speed data that the main control processors can use. |
| Architecture | It is a complex printed circuit board designed to plug into the modular architecture of the Mark V’s VME rack. It manages real-time data crucial for precise closed-loop control. |
| Firmware Role | The suffix AZZ02A confirms that the board is pre-loaded with a specific firmware/software package. This specialized software is necessary to accurately execute the complex conversion and filtering algorithms required for resolver feedback. |
| Hardware Components | Features several components required for signal conditioning, protection, and conversion, including: * Transformers * High-voltage electrolytic capacitors * Heat sinks * Jumper switches and Potentiometers for configuration and tuning. |
| Importance | This card is essential for the speed control, synchronization, and overspeed protection logic of the turbine, as it provides the high-fidelity rotational data needed by the Mark V’s TMR (Triple Modular Redundancy) controllers. |
In short, the DS215LRPBG1AZZ02A is the dedicated interface that allows the digital control system to “see” the exact rotational speed and position of the turbine shaft in real-time.3
