I can provide information on the GE DS2020UCOCN1G1A and the OC2000 Keypad Display, as they are two related but distinct components in GE’s control systems.
The part number DS2020UCOCN1G1A refers to the Unit Control Optimization Module (UCOM), which is the core processor board for the turbine. The second part of your query, OC2000 Keypad Display, refers to the Operator Control and Display unit used to interface with the system.
1. GE DS2020UCOCN1G1A (UCOM)
The DS2020UCOCN1G1A is a specialized, high-performance printed circuit board:1
| Feature | Description |
| Product Type | Universal Controller Module (UCOM) / Turbine Management Panel |
| Series/Family | GE Speedtronic Mark V Turbine Control Systems |
| Core Function | Primary Control Processor (The “Brain”). It houses the main CPU for the control system, executing the high-speed, deterministic algorithms for turbine control (fuel, speed, temperature, sequencing). |
| Architecture | It operates within the Triple Modular Redundancy (TMR) framework of the Mark V, where three UCOM boards (R, S, and T) run the same code simultaneously to ensure fault tolerance. |
| Revision | The suffix ‘A’ indicates a specific revision of the board following the initial DS2020UCOCN1G1. |
2. GE OC2000 Keypad Display
The OC2000 is the Operator Control Panel used with the DS2020-based drive and control systems:
| Feature | Description |
| Product Type | Operator Control and Display Panel / Keypad |
| Compatibility | Used with GE DC2000 and Mark V Adjustable Speed Drives. |
| Function | Provides the Human-Machine Interface (HMI) for the drive. Operators use the keypad and display to: * View drive status and operating parameters. * Enter commands (e.g., Run, Stop, Jog). * Access and modify configuration settings and fault history. |
| Interface | It is typically a digital display (often 2-line or 4-line LCD) with a membrane keypad for input. |
The UCOM (DS2020UCOCN1G1A) executes the control logic, and the OC2000 Keypad Display is the primary local tool an operator uses to interact with the system being controlled by the UCOM.
