Description
GE DS3800DGRA Speedtronic Mark IV Regulator Auxiliary Card
Product Overview
The GE DS3800DGRA is a regulator auxiliary card designed for GE’s Speedtronic Mark IV gas turbine control system. As a critical component within the Mark IV platform, this board provides advanced signal conditioning, control logic, and power management for industrial power generation, oil & gas, and marine propulsion applications. Unlike its sister models (e.g., DS3800DGRC1C1D), the DS3800DGRA focuses on auxiliary regulation functions, acting as a bridge between turbine control logic and field devices to ensure stable voltage and current output under dynamic load conditions. Its modular design and rugged construction make it suitable for harsh environments, while built-in diagnostic features enhance system reliability and reduce downtime.
Featuring a blue conformal coating and 1 trimmer resistor for manual adjustments 3, the DS3800DGRA includes multiple potentiometers and wire terminals for precise parameter tuning. Its compact form factor (33.0 cm x 17.0 cm x 2.5 cm, 2.0 kg) 1 allows seamless integration into existing Mark IV racks, with 40-pin connectors and retention latches ensuring secure signal transmission 6. The board supports RS-485 and Ethernet communication 1, enabling real-time data exchange with higher-level control systems.

Key Features and Advantages
Precision Signal Conditioning: The DS3800DGRA processes analog and digital signals from turbine sensors, ensuring accurate feedback to the main control board. Its trimmer resistor allows field technicians to fine-tune resistance values for optimal performance 3.
Robust Communication Capabilities: With RS-485 and Ethernet support, the board enables seamless integration with modern SCADA systems, facilitating remote monitoring and predictive maintenance 1.
Rugged Durability: Built with a corrosion-resistant aluminum alloy casing and conformal coating, the DS3800DGRA withstands dust, moisture, and extreme temperatures, making it ideal for offshore platforms and high-vibration industrial environments 1.
Diagnostic and Fault Recovery: Some variants (e.g., DS3800DGRA1E1C) include a restart button to resolve signal corruption issues without power cycling the entire system 6.
Legacy Compatibility: Designed for the Mark IV system, the DS3800DGRA ensures backward compatibility with older GE Speedtronic infrastructure, offering a cost-effective upgrade path 6.
Applications
The GE DS3800DGRA is widely used in gas turbine control systems across industries requiring precise auxiliary regulation:
- Power Generation: Managing voltage and current stability during grid synchronization and load shedding.
- Oil & Gas: Providing auxiliary control for turbine-driven compressors and pumps in refineries and offshore platforms.
- Marine Propulsion: Supporting propulsion systems by regulating power output for variable-speed marine turbines.
- Industrial Manufacturing: Ensuring consistent power supply for turbine-driven processes in chemical plants and steel mills.
