Description
Product Overview
The GE DS200TBQGG1A is a high-performance analog/digital termination module designed for GE’s Speedtronic Mark V turbine control system, a legacy platform widely used in power generation, oil & gas, and industrial automation. As part of the DS200 series of I/O interface solutions, the DS200TBQGG1A serves as a critical link between field sensors/actuators and the Mark V controller, enabling precise signal conditioning and transmission in harsh industrial environments. It supports a wide range of signal types, including 4-20 mA analog inputs, thermocouples, RTDs, and discrete digital signals, making it ideal for applications requiring mixed signal processing.
Integrated with the Mark V system’s RST (Remote Signal Termination) architecture, the DS200TBQGG1A interfaces with terminal blocks like CTBA and TBQA to handle up to 154 discrete signal connections through its dual terminal blocks (77 terminals each) 1. Its 15 jumpers (BJ1–BJ15) allow configurable signal scaling for voltage/current inputs, while 34-pin and 16-pin connectors (JGR, JHR, JGS/T) ensure seamless communication with core control modules like DS200TCCAG1B 110. The module’s multilayer PCB design and industrial-grade components provide robust immunity to electromagnetic interference, ensuring stable operation in high-vibration turbine environments. With 250 V continuous isolation and -40°C to +85°C operating temperature range, the DS200TBQGG1A delivers field-proven reliability in mission-critical applications.

Main Features and Advantages
The DS200TBQGG1A stands out for its versatile signal handling and field-proven ruggedness. Its dual terminal blocks support simultaneous analog and digital signal termination, reducing cabling complexity in turbine control panels. The module’s jumper-configurable signal scaling allows seamless integration with legacy systems, enabling users to adapt to voltage (0–10 V) or current (4–20 mA) inputs without hardware modifications 1. For example, jumpers BJ8–BJ15 configure analog channels for current/voltage operation, while BJ1–BJ7 enable burden resistor installation for pressure transducer inputs 1.
Reliability is a core strength: the DS200TBQGG1A incorporates electrical isolation to prevent ground loops and includes test points (TP1–TP3) for diagnostic access to critical circuits 20. Its removable connector design facilitates quick module replacement during maintenance, minimizing downtime. The module also supports hot-swap capabilities, allowing in-system upgrades without powering down the entire Mark V system. With IP65-rated dust/moisture resistance and shock/vibration tolerance, the DS200TBQGG1A excels in extreme industrial settings.
Application Areas
The DS200TBQGG1A is widely deployed in gas and steam turbine control systems for power plants, refineries, and industrial machinery. In gas turbines, it interfaces with vibration transducers, fuel flow transmitters, and compressor discharge sensors, providing real-time data to the Mark V controller for safe and efficient operation 1021. The module’s 4-20 mA outputs drive actuators like inlet guide vanes and fuel valves, ensuring precise load regulation during start-up and shutdown sequences.
In process automation, the DS200TBQGG1A supports distributed control systems (DCS) in chemical plants and water treatment facilities. Its RTD inputs monitor reactor temperatures, while discrete digital channels manage solenoid valves and motor starters. The module’s Corebus communication integrates seamlessly with GE’s Speedtronic system, enabling centralized diagnostics and remote configuration. For example, it can be paired with DS200TCCAG1B analog I/O modules to create hybrid control loops for temperature and pressure regulation 6.

Installation and Maintenance
Installation: Mount the DS200TBQGG1A in the Mark V system’s R5 core chassis, ensuring proper grounding. Connect field wiring to the dual terminal blocks using 22–16 AWG shielded cables, following the terminal layout specified in GE’s GEI-100168 manual 22. Configure jumpers (BJ1–BJ15) based on the application’s signal requirements (e.g., current/voltage selection). Use GE-approved fuses (5×20 mm, 800 mA) to protect input channels from overcurrent.
Maintenance: Regularly inspect the module for loose connections or physical damage. Clean dust with a static-free cloth and verify LED indicators for 异常状态. To replace the board, transfer PROM modules from the old unit to the new DS200TBQGG1A using an anti-static wrist strap. Calibrate analog inputs annually using GE’s Proficy software to maintain accuracy.
