The GE DS3800DVRC is a URAL Daughter Card used in the GE Speedtronic Mark IV series of turbine control systems. As a “daughter board,” it plugs into a larger main circuit board to extend its functionality, specifically for voltage regulation and control.
Function and Purpose
The primary purpose of the DS3800DVRC is to act as a regulator card and mitigate energy spikes within the turbine control system. Its key roles include:
- Voltage Regulation: The board’s main function is to regulate the voltage output, ensuring that the control system receives a stable and consistent power supply. This is critical for the proper operation and longevity of sensitive electronic components.
- Protection: The board is designed to mitigate power surges and energy spikes. It incorporates components like fuses to prevent overvoltage situations and protect circuits from damage.
- Signal Processing: It takes commands from the main control processor and translates them into the necessary signals to control and regulate the system’s power.
- System Integration: As a daughter board, it allows for a modular design, enabling the main control board to handle a wide range of applications by simply adding the appropriate daughter cards.
Technical and Design Features
The DS3800DVRC is a legacy industrial control board, reflecting the technology of the GE Mark IV series.
- Legacy Part: The “DS3800” prefix indicates that it is a legacy GE industrial part from a series that is no longer in production by the manufacturer. These boards are now sourced from surplus, repair, and refurbishment channels for the maintenance of older turbine control systems.
- Daughter Board: Its “daughter board” designation means it is a smaller, auxiliary card that connects to a larger main board, typically through a set of pin headers.
- Hardware: The board is populated with various electronic components, including capacitors, resistors, fuses, and a 34-pin connector. It also features jumpers and indicator LEDs for configuration and diagnostics.
Applications and Importance
The DS3800DVRC is a fundamental component in legacy GE turbine control systems. Its importance lies in the fact that it provides the necessary voltage regulation and protection capabilities to ensure the stability and efficiency of the entire control system. Without this board, the system’s ability to maintain stable power levels would be severely impaired, potentially leading to a system malfunction or shutdown.
