💻 The GE DS215SDCCG1AZZ01B Drive Control Card is a highly specialized and essential printed circuit board (PCB) assembly used in General Electric’s industrial control and drive systems, specifically within the Mark V Turbine Control Series and related AC2000, DC2000, and EX2000 drive applications.1
It is the primary control board for the drive system, housing the core processing power and logic.2
⚙️ Key Specifications and Function
| Feature | Specification/Description |
| Product Type | Standard Drive Control Card (SDCC) / Main Control Board |
| Series/Family | GE Speedtronic Mark V Turbine Controls, DC2000, and EX2000 Systems |
| Core Function | Drive/Exciter Control. Executes the main, high-speed control algorithms for industrial drives (regulating speed, torque, voltage, and current) and exciter systems. |
| Processor Architecture | Features three main microprocessors for distributed processing: * Drive Control Processor (DCP): Manages user interfaces, external loops (speed, location), and system I/O. * Motor Control Processor (MCP): Handles math-intensive functions related to motor control. * Co-Motor Processor (CMP): Provides additional processing capability. |
| Firmware Role | The suffix AZZ01B is crucial, confirming that the board comes pre-loaded with a specific firmware/software package. The ‘B’ revision indicates a functional or software update from the ‘A’ version. |
| I/O and Connections | Includes multiple connectors (e.g., 1PL, 2PL, 3PL, etc.) for crucial connections, transmitting and receiving signals to and from other boards within the drive system. |
| Diagnostics | Features built-in functions for fault detection and includes on-board LEDs to display status and fault codes, aiding troubleshooting. |
| Expandability | Designed with mounting structures to accommodate optional daughterboards, such as LAN Communication Cards (like the DS215SLCC) or Signal Processor Cards (SPC), to enhance functionality. |
The DS215SDCCG1AZZ01B is a cornerstone component that ensures the precise, reliable, and efficient operation of the high-power drives and exciters it controls.3
