FUNCTIONAL DESCRIPTION:
DS3800DRFA1B is an Auxiliary Regulator Board manufactured and designed by General Electric and is part of the Mark IV Series used in GE Speedtronic gas turbine control systems. It functions primarily to regulate and stabilize auxiliary DC voltages required for the proper operation of the turbine control logic. The board provides signal conditioning by filtering noise and buffering input signals to ensure accurate and reliable control system performance. It supports pulse inputs ranging from 10 Hz to 25 kHz, which allows it to interface effectively with various sensors and control devices. Designed for rugged industrial environments, the board maintains electrical stability and signal integrity across the operating temperature range of –40 °C to +70 °C, ensuring continuous, precise turbine control.
INSTALLATION:
Before installation, ensure that all power sources to the control system are completely disconnected. The DS3800DRFA1B Auxiliary Regulator Board is designed for plug-in installation within the Mark IV Speedtronic control rack. Align the board’s edge connector with the mating connector on the motherboard or backplane and carefully insert the board until fully seated. Secure the board using the provided fastening hardware to prevent displacement during system operation. Connect any required auxiliary cables or ribbon connectors per the system wiring diagram and installation guidelines. Verify all connections are properly seated and oriented before reapplying power to the control system.
OPERATION:
Upon application of power, the board automatically begins regulating auxiliary voltages required by the turbine control system. The board provides continuous voltage stabilization, filtering, and buffering to maintain signal integrity and reduce electrical noise. It accepts pulse input signals ranging from 10 Hz to 25 kHz and converts these signals for use by the primary control processor. The board is designed to operate reliably within an ambient temperature range of –40 °C to +70 °C and is continuously monitored by the Mark IV diagnostic system. Any faults or deviations detected during operation are reported through the system’s diagnostic routines to facilitate prompt maintenance actions.
