Product Overview
The DS200SLCCG3ADC is a servo control interface card manufactured by General Electric (GE), serving as a key component in its Mark Vie turbine control system. This card undertakes the core interface function, responsible for managing the precise control signal transmission between the system's main processor and the servo valves, which are used to drive fuel control, guide vanes and other key turbine mechanisms. Its "ADC" logo highlights the enhanced analog-to-digital conversion capability, which is crucial for precise feedback signal processing.
As a reliable product in the Speedtronic series, the DS200SLCCG3ADC is specifically designed for critical power generation applications, featuring high performance and fault-tolerant operation, ensuring stable and efficient control of turbine speed and load.
Features and Functions
Provide precise control signals for controlling one or more servo valves to ensure the accurate positioning of the actuator.
Advanced feedback processing: The integrated ADC circuit can convert analog feedback signals (such as those from LVDT) into digital data required to control the processor at high resolution, thereby achieving strict closed-loop control.
Regulate the input (control signal) and output (feedback signal) to provide anti-noise capability and prevent common ground loops and voltage spikes in industrial environments.
The comprehensive diagnostic function continuously monitors the operating status of the servo circuit, including coil continuity, feedback signal effectiveness and stroke limit. The DS200SLCCG3ADC can issue an alarm and activate protective measures when a fault is detected.
The manual test function enables operators and technicians to manually test the servo output and simulate feedback for system verification and troubleshooting without starting the turbine.
Designed for redundant (1/1 or 1/2) configurations, it ensures the system has the highest availability and reliability. If the primary card fails, the standby card can seamlessly take over the control.

Product Applications
The GE DS200SLCCG3ADC servo control card is specifically designed for the following industrial applications and plays a key role in them:
Power generation
In gas turbine power plants, the fuel flow rate entering the combustion chamber is precisely controlled to maintain stable combustion and cope with load changes.
In a steam turbine power plant, the speed and power output of the steam turbine are controlled by adjusting the steam intake valve.
The DS200SLCCG3A is a component of the coordinated control of gas turbines and steam turbines in combined cycle power plants.
Industrial drive
GE servo control interface card is used for large mechanical drive steam turbines, such as compressor stations and pumping stations in the oil and gas industry, where constant-speed operation under variable loads is required.
The ship propulsion industry is used for navies or large merchant ships that adopt steam turbine propulsion systems.
