Description
Product Overview
The GE DS200TBQBG1ACB 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 RST (Remote Signal Termination) series, this module serves as a critical interface 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, LVDT/RVDT position sensors, and discrete digital signals, making it ideal for applications requiring mixed signal processing in gas turbine control systems like the LM6000.
Integrated with the Mark V system’s RST architecture, the GE DS200TBQBG1ACB interfaces with terminal blocks like CTBA and TBQA to handle up to 154 discrete signal connections through its dual terminal blocks (77 terminals each). 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. 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 GE DS200TBQBG1ACB delivers field-proven reliability in mission-critical applications.

Main Features and Advantages
The GE DS200TBQBG1ACB excels in versatility and ruggedness, making it a cornerstone of Mark V turbine control systems. Its dual terminal blocks (77 terminals each) support simultaneous handling of analog and digital signals, reducing wiring complexity in turbine control panels. The 15 configurable jumpers (BJ1–BJ15) enable precise signal scaling for voltage (0–10 V) or current (4–20 mA) inputs, eliminating the need for hardware modifications when integrating with diverse field devices like pressure transducers or position sensors.
Reliability is a defining trait: the GE DS200TBQBG1ACB features 250 V electrical isolation to prevent ground loops and includes test points for quick diagnostic access, simplifying troubleshooting. Its removable connector design allows hot-swap capability, enabling module replacement without powering down the entire Mark V system—critical for minimizing downtime in mission-critical applications. With IP65-rated dust and moisture resistance and tolerance to high vibration, the module thrives in extreme industrial environments, from power plant turbine halls to offshore platforms.
Application Areas
The GE DS200TBQBG1ACB is primarily deployed in gas and steam turbine control systems across power generation, oil & gas, and industrial sectors. In gas turbines like GE’s LM6000, it interfaces with vibration transducers, fuel flow meters, and inlet guide vane position sensors, relaying real-time data to the Mark V controller for precise speed and load regulation. Its 4-20 mA outputs drive actuators such as fuel control valves, ensuring smooth operation during start-up, shutdown, and load changes.
Beyond turbines, the module supports process automation in refineries and chemical plants, where it connects to temperature transmitters (via RTD inputs) and solenoid valves (via discrete digital channels). Integrating with GE’s Speedtronic system, the GE DS200TBQBG1ACB enables centralized monitoring and control, making it invaluable for maintaining operational efficiency in distributed control systems (DCS) requiring mixed signal processing.
