Overview

The GE DS200PTCTG1BAA is a Signal Conditioner Card designed for use in General Electric’s Mark V Turbine Control System Series. This series supports steam, gas, and wind turbine control systems and incorporates the last generation of Speedtronic control technology. Although the Mark V Series is now considered obsolete, it remains widely utilized due to its reliability and proven performance in industrial turbine automation systems.

The DS200PTCTG1BAA is a revised version of the original DS200PTCTG1 model and is sometimes referred to as a Potential Transformer Current Transformer (PT/CT) in official GE documentation.

Key Functions

• Signal Conditioning: Scales and isolates voltage and current signals from connected PTs (Potential Transformers) and CTs (Current Transformers).

• Auxiliary I/O Support: Provides auxiliary low-voltage inputs and outputs for Mark V Series systems.

• Interfacing Capability: Interfaces with the TCCB board via the JKK connector, accepting secondary isolation transformers.

Hardware Features

Installation & Interference Mitigation Tips

Due to its connectivity with numerous signal wires, signal interference is a potential issue if installed improperly. Proper installation planning is essential to minimize this risk.

Best Practices for Reducing Signal Interference:

• Separate Power and Signal Cables: Route high-voltage power cables away from signal cables.

• Cable Bundling: Bundle signal and power cables separately.

• Avoid Long Parallel Runs: If unavoidable, increase the physical distance between cable types.

• Right-Angle Routing: Run power and signal cables at 90-degree angles to reduce electromagnetic exposure.

• Shielded Cables: In high-interference environments, use shielded cables for additional protection.

Applications

• Wind, steam, and gas turbine systems

• Industrial automation with legacy Mark V Series systems

• Voltage and current signal scaling and isolation

Legacy Status

• Obsolete: No longer manufactured by GE

• Availability: Typically available in surplus markets (new and used conditions)

• Documentation: Installation and operational guidance available through original GE manuals

Note

While this board includes enhanced functionality from its three-tier revision history, all configuration and installation should adhere to the original GE Mark V specifications for optimal performance and safety.
