Description
DS200PCCAG7ACB: Product Overview
The GE DS200PCCAG7ACB is a power connect card designed specifically for GE Speedtronic™ Mark V distributed control systems (DCS), the industry standard for gas, steam, and hydro turbine control in power generation. As part of the Mark V ecosystem, it acts as the “power bridge” between the DC2000 drive (used for turbine speed control) and the SCR power bridge (used for power conversion). Its primary role is to ensure reliable DC power distribution to critical control components, which is essential for maintaining turbine stability and preventing unplanned downtime.
Engineered for the demanding conditions of turbine halls, the DS200PCCAG7ACB features a robust PCB layout and secure connector interfaces to withstand continuous DC power transmission. Its legacy compatibility makes it ideal for retrofitting aging Mark V systems—common in power plants operating turbines for 20+ years—where replacing the entire control architecture is cost-prohibitive. Whether used in 7EA gas turbines or 9F steam turbines, the DS200PCCAG7ACB ensures stable power delivery, directly extending the operational life of critical turbine control systems.
Role in Automation Systems
Positioned as a “power hub” in Mark V architectures, the DS200PCCAG7ACB performs two primary functions:
-
Power Distribution: Routes DC power from the DC2000 drive to the SCR power bridge, ensuring each component receives the correct voltage and current. This is critical for maintaining turbine speed and load control.
-
Interconnection: Connects the DC2000 drive to the SCR power bridge via secure interfaces, minimizing power loss and ensuring signal integrity.
Its core value lies in stabilizing power supply—a critical requirement for turbine control, where even minor voltage fluctuations can lead to process instability (e.g., turbine speed variations) or equipment damage (e.g., excitation system failure).
Core Functionality
-
DC Power Connection: The DS200PCCAG7ACB is designed to connect the DC2000 drive to the SCR power bridge, providing a stable DC power interface. This ensures that the SCR power bridge receives consistent power for reliable power conversion.
-
Snubber Support: Supports both AC and DC type snubbers, which are used to suppress voltage spikes and transients. This protects sensitive control electronics from high-voltage surges, ensuring reliable operation in harsh industrial environments.
-
Bus Compatibility: Works with separate or common bus transformers, allowing flexibility in system design. This makes it suitable for a wide range of turbine control applications, from small gas turbines to large steam turbines.
-
Hardware Customization: Includes four adjustable hardware jumpers for system customization, allowing engineers to adapt the card to different operational requirements. This flexibility reduces the need for additional hardware modifications, saving time and money during installation.

Core Features & Customer Value
1. Reliable Power Distribution:
The DS200PCCAG7ACB’s robust design ensures stable DC power delivery to the SCR power bridge, even in harsh industrial environments. For example, in a power plant, the card can handle voltage fluctuations from the grid and still provide consistent power to the turbine controller, preventing unexpected shutdowns.
2. Flexibility in System Design:
Supports both AC and DC snubbers and works with separate or common bus transformers, allowing engineers to customize the system to meet specific operational requirements. This flexibility reduces the need for additional hardware modifications, saving time and money during installation.
3. Legacy Compatibility:
Designed to work with existing Mark V components (e.g., DC2000 drives, SCR power bridges), the DS200PCCAG7ACB eliminates the need for costly system upgrades. This makes it an ideal choice for power plants with aging Mark V systems, where replacing the entire control architecture is not feasible.
4. Easy Maintenance:
The card’s modular design allows for quick replacement during maintenance, reducing downtime. The adjustable hardware jumpers simplify system customization, allowing technicians to adapt the card to different operational requirements without extensive reconfiguration.
