GE LCI System DS200DDTBG2A Digital Analog Diagnostic Terminal Board

GE LCI System DS200DDTBG2A Digital Analog Diagnostic Terminal Board

DS200DDTBG2A is a DDTB digital analog diagnostic terminal board for the GE Vernova Speedtronic Mark V/LS2100 static start LCI system, which belongs to the signal interface board supporting the turbine static start control system. DS200DDTBG2A serves as a signal conditioning and terminal conversion unit between on-site sensors, actuators, and the main control DSP board, responsible for collecting high-voltage AC signals, current monitoring signals, switch inputs, and outputting analog and isolated digital signals. The board completes signal filtering, level conversion, and signal isolation, standardizes various raw signals on site and sends them to the main control processor. At the same time, it undertakes circuit diagnosis function, monitors the line status in real time, and provides signal acquisition, output, and fault diagnosis for gas turbine and turbine LCI static start control, ensuring stable and reliable unit start-up, excitation, and speed regulation processes.

Product features

1. Integrate multiple high-voltage AC, current, analog, and switch signal interfaces to complete on-site signal conversion, conditioning, and isolation in one stop, simplifying the external wiring of LCI systems.
2. Onboard passive filtering and signal voltage reduction circuit, preprocesses high-voltage input signals to reduce strong electrical interference and protect the backend main control board.
3. Equipped with jumper configuration bits, the signal range and signal routing can be flexibly adjusted to adapt to different on-site sensor specifications of the unit.
4. Optoelectronic isolation output channel, achieving strong and weak electrical isolation, blocking on-site interference from entering the control system, and enhancing the system’s anti-interference ability.
5. PCB with conformal coating, moisture-proof and corrosion-resistant, suitable for high humidity and high dust industrial environments inside power plant control cabinets.
6. Built in hardware circuit diagnosis can identify signal disconnection, over range, and short circuit faults, and upload fault information to the Mark V main control.
7. European card rack mounted installation, directly inserted into the Mark V chassis backplane, paired with flat cables for communication with the ADMA board, easy to disassemble and maintain.
8. Designed specifically for the LS2100 LCI static start-up unit, it is natively compatible with the entire Mark V turbine start-up control hardware for monitoring during the unit start-up phase.
