TC2000 Turbine Control Analog Module | DS200TCCAG1BAA GE

Product Overview

The GE DS200TCCAG1BAA serves as a high-performance Analog I/O Board within the Speedtronic™ Mark V turbine control and TC2000 drive platforms. It executes the critical task of interfacing the control core with variable field signals, including pressure, temperature, and flow data. By processing high-accuracy analog inputs and generating precise output commands for actuators, this board maintains the closed-loop stability necessary for steam and gas turbine operation. It occupies a central role in the Mark V rack, converting physical process variables into the digital intelligence required for turbine protection and regulation.

Condition: 100% Brand New and Original in Factory Packing.

Technical Specifications

The DS200TCCAG1BAA utilizes professional-grade A/D conversion and robust communication bus interfaces to ensure zero-latency data throughput.

Engineering Advantages

• Configurable Signal Adaptation: The board features eight hardware jumpers (J1–J8) that allow onsite technicians to customize signal scaling and input types. This flexibility eliminates the need for multiple board variants, as one DS200TCCAG1BAA adapts to various turbine control configurations via simple physical settings.

• Real-Time Diagnostic Feedback: A dedicated LED block with 10 status indicators provides instantaneous visual health checks. These LEDs allow maintenance teams to identify communication faults or power irregularities immediately, significantly reducing Mean Time to Repair (MTTR) during critical outages.

• High-Bandwidth Processing: The integrated CPU and onboard SRAM handle complex signal linearization and engineering unit conversions at the board level. By offloading these tasks from the main control core, the DS200TCCAG1BAA improves the overall response time of the turbine’s governor and protection loops.

• Industrial-Grade Thermal Resilience: Engineered for harsh turbine hall environments, this module maintains 100% accuracy across a broad temperature range of -40°C to +70°C. The robust PCB coating protects against the humidity and airborne contaminants typically found in industrial power plants.

• Seamless TMR Integration: The DS200TCCAG1BAA fully supports Triple Modular Redundant (TMR) architectures. It synchronizes analog data across the R, S, and T cores, ensuring that the control system performs accurate hardware voting to prevent nuisance trips caused by sensor drift.

FAQs

Q: What distinguishes the DS200TCCAG1BAA from the TCDA digital board?

A: The TCCA (DS200TCCAG1BAA) focuses exclusively on analog signals, such as 4-20mA loops and variable voltage inputs. The TCDA board handles discrete "on/off" digital signals. While they share a similar form factor, their internal A/D and D/A conversion circuitry serves entirely different measurement types.

Q: Does this module require firmware loading upon installation?

A: This board contains 32 KB of non-volatile EEPROM. While it arrives with factory-default settings, you must verify that the onboard software revision matches your specific turbine's control parameters. Configuration typically occurs via the Mark V Toolbox software during the commissioning phase.

Q: How do I verify if the hardware jumpers are set correctly?

A: Always refer to the unit's original elementary drawings (Control Specifications). The J1–J8 jumpers must match the configuration of your previous board to ensure the signal gain and offset remain consistent with the connected field instrumentation.

Q: Is this board compatible with both gas and steam turbine Mark V systems?

A: Yes. The DS200TCCAG1BAA serves as a universal analog interface for the Speedtronic™ Mark V platform, provided the backplane and ribbon cable configurations align with the TCCA board's technical pinouts.
