Product Overview
The DS200SLCCG3ADC is a Servo Control Interface Card manufactured by General Electric (GE) as a key component for its Mark Vie Turbine Control System. GE DS200SLCCG3ADC serves as a critical interface, managing the precise control signals between the system's main processors and the servo valves that actuate fuel controls, inlet guide vanes, and other critical turbine mechanisms. The "ADC" designation highlights its enhanced Analog-to-Digital conversion capabilities, which are essential for accurate feedback signal processing.
As part of the reliable Speedtronic series, the DS200SLCCG3ADC is engineered for high performance and fault-tolerant operation in critical power generation applications, ensuring stable and efficient control over turbine speed and load.
Features and Functions
High-Precision Servo Control: GE DS200SLCCG3ADC provides precise command signals to control one or multiple servo valves, ensuring accurate actuator positioning.
Advanced Feedback Processing: The integrated ADC circuitry allows for high-resolution conversion of analog feedback signals (e.g., from LVDTs) into digital data for the control processor, enabling tight closed-loop control.
Signal Conditioning and Isolation: Conditions both input (command) and output (feedback) signals, providing noise immunity and protection against ground loops and voltage spikes common in industrial environments.
Comprehensive Diagnostics: GE DS200SLCCG3ADC continuously monitors the health of the servo loop, including coil continuity, feedback signal validity, and travel limits. DS200SLCCG3A can generate alarms and initiate protective actions upon detecting faults.
Manual Test Functionality: GE DS200SLCCG3ADC allows operators and technicians to manually test servo output and simulate feedback for system verification and troubleshooting without starting the turbine.
Redundancy Support: GE DS200SLCCG3ADC designed to operate in a redundant (1-out-of-1 or 1-out-of-2) configuration, ensuring maximum system availability and reliability. If a primary card fails, a backup card can take over control seamlessly.
