DS2020DACAG2 REVC 2 Digital-to-Analog Converter Module

Precision Digital-to-Analog Converter Module for Turbine Control

Technical Specifications

Main Features and Advantages

Precision Control Outputs: The GE DS2020DACAG2 delivers exceptional ±0.05% accuracy for critical turbine control applications. Its dual-range outputs (4-20mA or ±10V DC) provide flexible interface options for actuators, valves, and positioning systems. The 16-bit resolution ensures smooth, precise control signal generation essential for stable turbine operation under varying load conditions.

Redundant Architecture: Designed for mission-critical applications, this module features built-in self-diagnostics that continuously monitor output integrity. Automatic fault detection triggers redundant channel switching within 10ms, preventing uncontrolled shutdowns in power generation systems. The GE DS2020DACAG2 maintains signal accuracy even during voltage transients through advanced power conditioning circuitry.

Intelligent Calibration: The module’s non-volatile memory stores calibration parameters, maintaining precision throughout its operational life. Automatic temperature compensation adjusts output signals based on ambient conditions, ensuring consistent performance across the 0°C to 60°C operating range. Field calibration can be performed without removing the module from the rack, reducing maintenance downtime.

Seamless System Integration: As part of GE’s Mark VI Speedtronic platform, the GE DS2020DACAG2 integrates directly with turbine control processors via VME bus. Configuration tools automatically recognize module parameters, simplifying system commissioning. LED status indicators provide immediate visual feedback for channel activity and fault conditions.

Robust Industrial Design: Engineered for power plant environments, the module features gold-plated connectors and conformal-coated circuitry to withstand humidity and contaminants. Vibration-resistant mounting ensures reliable operation in turbine halls where mechanical vibrations are prevalent. The module’s hot-swappable design allows replacement without system shutdown, minimizing production losses.
