Description
GE DS200IMCPG1CGC
Technical Specifications
- Manufacturer: General Electric (GE).
- Product Type: RST Analog I/O Board.
- Functional Acronym: TCQA.
- Series: Mark V.
- Hardware Jumpers: Includes J1, J2, J5, J6, J7, and J8 for configuring output circuits and testing.
Functional Features
- Signal Conditioning: Scales and conditions numerous analog signals, including LVDT inputs, servo valve outputs, thermocouple inputs, 4-20 mA inputs/outputs, vibration inputs, relay driver outputs, pulse inputs, voltage inputs, and generator/line signals.
- Data Bus Transmission: Transmits conditioned signals to the COREBUS via the 3PL connector.
- Generator and Line Signals: Uses the JE connector to send and receive generator and line signals to/from the TCQC board.
- Signal Routing: Routes specific 4-20 mA input signals (such as compressor stall detection and fuel flow pressure) for processing.
Application Scenarios
Deployed in industrial gas turbine control systems where precise analog signal conditioning, monitoring, and control are required for safe and efficient turbine operation.
Performance Parameters
- Milliamp Output Configuration: J1 and J2 are used to select the milliamp output circuit. J5 and J6 configure the output current range, which can be set to either 20 mA or 200 mA.
- Testing and Oscillation: J7 is utilized for card testing via the RS232 port, while J8 is used to start the oscillator.
Material Composition
Constructed with high-reliability industrial-grade printed circuit boards (PCBs) and precision electronic components designed to withstand the harsh electrical and thermal environments of power generation facilities.
Structural Characteristics
Features multiple specialized connectors for system integration, including 2PL for power distribution, 3PL for data bus connections, JB for 4-20 mA inputs/outputs, JD for trip signals, JE for pulse and generator signals, and JF/JG for LVDT and vibration inputs.
Working Principle
The board acts as an intermediary signal processor. It receives raw analog signals from various turbine sensors via terminal boards, scales and conditions these signals to appropriate levels, and routes them through specific connectors to the core processing units for real-time turbine control and protection logic.
Installation Requirements
Must be correctly seated into the designated I/O core slot within the Mark V control rack. All associated ribbon cables and signal wires must be accurately routed and connected to the corresponding terminal boards according to the hardware jumper panel guidelines.
