GE DS200TCSAG1A Fuel Skid Interface Board

الوصف

The GE DS200TCSAG1A is a specialized circuit board known as the Fuel Skid Interface Board or UC Pressure Transducer Interface within the GE Speedtronic Mark V Turbine Control System.¹

It plays a critical role in the operation of gas turbines, particularly those using Dry Low Emissions (DLE) technology, by managing the communication and processing of high-resolution fuel-related signals.²

⛽ Function and Location

Primary Function

The primary function of the DS200TCSAG1A (TCSA) is to act as a signal decoder and interface for the fuel control system.³ It is responsible for:

1. Pressure Transducer Signal Decoding: It decodes the serial protocol signals (specifically RS422 protocol) received from high-resolution pressure transducers located on the external fuel skid.⁴
2. Fuel Skid Interface: It interfaces with the XD⁵SA board (a digital input/output board) on the fuel skid to manage and receive these pressure signals.⁶
3. Data Transmission: It writes the decoded transducer signals to the UCIB board (Unit Control Interface Board) for processing by its dedicated 196 processor.⁷
4. Power Supply: It provides ⁸$\text{12 VDC}$ excitation power to the pressure transducers and the FMVED (Fuel Metering Valve Electric Drive) motor controllers.⁹

System Location

• Series: GE Speedtronic Mark V Turbine Control System.¹⁰
• Core: Typically mounted in the R core of the Mark V panel.¹¹
• Interfacing Boards: It directly interfaces with the XD¹²SA board on the fuel skid and the UCIB board within the Mark V control panel.¹³ Signals are often routed through the TBSA terminal board to the TCSA board via the P3 connector.
