Description
Product Overview
The GE DS200SDCCG1AEC is a Drive Control Card engineered for GE’s Mark V series of industrial control systems, specializing in SCR (Silicon-Controlled Rectifier) drive and generator excitation applications in power generation, oil & gas, and heavy machinery industries. As a critical component of the Speedtronic LST TMR (Triple Modular Redundancy) architecture, this board manages high-voltage signal conditioning and interface functions for turbine control systems, ensuring stable grid synchronization and overvoltage protection.
Integrated into the Mark V system’s protection core, the GE DS200SDCCG1AEC supports analog-to-frequency conversion for high-voltage shunt signals (-500 mV to +500 mV), converting them into differential frequency outputs (0–500 kHz) for power supply boards like DS200DCFBG1BLC and SDCI . Its 17 configurable jumpers and 10:1 current transformers enable adjustable attenuation for AC line, motor armature, and SCR bridge voltages, ensuring signal integrity in high-voltage environments. The board also features dual isolated VCO (Voltage-Controlled Oscillator) circuits for precise signal conversion and DC positive/negative floating shunts for enhanced flexibility.
Built for rugged industrial environments, the GE DS200SDCCG1AEC includes a standard conformal-coated PCB to resist moisture, dust, and electromagnetic interference (EMI). Its vibration-resistant construction and high-voltage isolation (up to 1000 V AC) make it suitable for turbine halls, offshore platforms, and other harsh settings. The board’s hot-swap capability minimizes downtime by allowing faulty units to be replaced without powering down the entire system .

Main Features and Advantages
High-Voltage Signal Conditioning: The GE DS200SDCCG1AEC converts high-voltage shunt signals from SCR bridges into low-frequency outputs compatible with power supply boards like DS200DCFBG1BLC. Its 10:1 current transformers and jumper-configurable attenuation allow adaptation to AC line voltages ranging from 240 V to 1000 V, ensuring compatibility with diverse drive systems .
Dual VCO Architecture: The board’s dual isolated VCO circuits provide redundant signal conversion, enhancing reliability in safety-critical applications. Each VCO supports differential frequency outputs for precise control of power supply modules, minimizing noise and signal distortion.
Ruggedized Design: The conformal-coated PCB and vibration-resistant mounting ensure stable performance in extreme conditions (0°C to +60°C). The board’s high-voltage isolation (1000 V AC) and IP67-rated dust/moisture resistance make it suitable for turbine systems subject to high electrical stress and mechanical vibration .
Modular Flexibility: With 17 configurable jumpers and multiple connector types, the board integrates seamlessly with other Mark V components like PCC A (Power Connect Card) and IMCP (Interface Module Control Processor). Its hot-swap capability and EPROM-based programming simplify field upgrades and reduce maintenance complexity.
Advanced Diagnostics: On-board LEDs and test points enable quick troubleshooting, while the 16-key alphanumeric programmer provides direct access to fault codes and system settings. This enhances predictive maintenance capabilities, reducing unplanned downtime and extending equipment lifespan.
Application Areas
Turbine Control Systems: The GE DS200SDCCG1AEC is critical for SCR bridge monitoring in gas and steam turbines, converting high-voltage shunt signals into control inputs for power supply boards. It interfaces with modules like DS200DCFBG1BLC to regulate generator excitation and motor armature currents, ensuring stable grid synchronization .
Power Generation: In power plants, the board facilitates real-time data exchange between the Mark V controller and DS200TCTGG1A (generator control board), supporting grid synchronization and overvoltage protection. Its ARCNET LAN connectivity also enables integration with supervisory control systems for centralized monitoring of turbine performance.
Heavy Industry: Ideal for refineries and chemical plants, the GE DS200SDCCG1AEC interfaces with PTBA terminal boards to monitor high-voltage process signals. Its DLAN support enables distributed control across multiple units, while remote diagnostics via RS232 reduce manual intervention and improve operational efficiency.
Renewable Energy: In wind turbine systems, the board manages variable frequency drive (VFD) control signals, converting high-voltage outputs from SCR bridges into low-frequency inputs for power supply modules. This ensures efficient energy conversion and grid integration. Additionally, it is used in solar power systems for control and management of energy distribution .

Installation and Maintenance
Installation Preparation: Before installing the GE DS200SDCCG1AEC, ensure the Mark V system is powered down and grounded. Use anti-static wrist straps to prevent ESD damage, and verify compatibility with existing modules (e.g., DS200DCFBG1BLC). Mount the board in the R5 core chassis using DIN rail or panel mounts, securing connectors with torque-controlled tools. Confirm proper jumper configuration based on input voltage requirements . For configuration, connect the board to a laptop via a serial cable attached to the optional LAN communications card, ensuring the serial port is correctly configured and the GE Proficy software is installed .
Maintenance Recommendations: Regularly inspect connectors for corrosion and clean the PCB with compressed air (avoiding direct airflow on components). Use GE’s Proficy software to recalibrate VCO parameters annually and update firmware during system downtime. Replace faulty units immediately to maintain system integrity, leveraging the hot-swap capability for seamless replacement. For TMR configurations, perform signal integrity checks and redundancy tests quarterly to ensure dual VCO circuits are operational. Configuration files stored on the board’s four EPROM chips can be transferred to a replacement board to preserve settings .
Product Guarantee
