GE DS200CPCAG1ABB Speedtronic Programmable Controller Board

Overview

The DS200CPCAG1ABB is a programmable controller processor board developed by General Electric for use within the Mark V Speedtronic turbine control architecture. Acting as a primary control and coordination element, this board processes operational logic, manages internal data exchange, and supports real-time turbine control functions for gas and steam turbine applications.

Designed for long-term deployment in demanding power generation environments, the CPCA board provides dependable system performance, fault visibility, and stable integration with associated Mark V I/O and communication boards.

Functional Role

Within the Mark V control rack, the DS200CPCAG1ABB serves as a central processing interface responsible for executing control algorithms, coordinating signal flow between subsystems, and maintaining communication integrity across the control platform. It supports deterministic operation required for turbine sequencing, protection logic, and operational monitoring.

Key Technical Characteristics

The board is engineered with industrial-grade components and protective surface treatment to ensure consistent performance in high-vibration and elevated-temperature turbine enclosures. Diagnostic indicators mounted directly on the board assist maintenance personnel in rapid fault identification and system status verification.

Frequently Asked Questions

Q: Is this board field-programmable?
A: Control logic is executed based on system configuration; programming and parameterization are handled at the system level rather than directly on the board.

Q: Does the board include built-in diagnostics?
A: Yes. On-board LED indicators provide immediate visual feedback on operational and fault conditions.

Q: Can this board be used as a direct replacement?
A: It is suitable as a direct replacement only when the full model number DS200CPCAG1ABB matches the original installed unit.
