FU NCTIONAL DESCRIPTION:
DS3800DRRA1B is a Reel Regulator Auxiliary Card manufactured and designed by General Electric and is part of the Mark IV Series used in GE Speedtronic gas turbine control systems. It functions as a supporting regulation module that enhances signal conditioning and voltage stability. Measuring approximately 2 inches high by 5 inches long, the board includes six heavy-duty terminals with retention screws, sixteen single-pin connectors, three jumpers, five resistors, and multiple capacitors that work together to filter noise and stabilize control signals. Its primary purpose is to interface accurately with the main regulator, ensuring clean and reliable signal transfer, as well as electrical isolation between system sections.
INSTALLATION:
The card is then secured into its designated Mark IV backplane slot using its four corner mounting holes and screws per the original GE chassis design. Electrical interface is achieved through the six screw-down terminals and sixteen pin connectors, which must be fastened to their corresponding harnesses and connectors in the rack. Proper seating and secure fastening are critical to avoid vibration-induced faults during turbine operation. Once mechanically secured and the board connections are verified, system power can be restored and diagnostics run to confirm full functionality.
�
OPERATION:
It processes input signals, filtering capacitive noise, buffering current through its resistors, and maintaining stable voltage levels across its terminals and connectors. The jumpers allow limited configuration or mode selection based on system requirements. Designed as a passive yet integral part of the Mark IV control system, the card does not require operator intervention during normal operation and automatically supports the control logic. Its auxiliary regulation stabilizes field signals, contributing to the overall precision, reliability, and safe functioning of turbine control loops.
