GE DS200TBQAG1A Analog/Digital Termination Module(XIONGBA)

Description

Product Overview
The GE DS200TBQAG1A is a high-performance analog/digital termination module designed for seamless integration with GE’s Speedtronic Mark V turbine control system, a cornerstone of industrial automation in power generation, oil & gas, and heavy industry. As part of the RST (Remote Signal Termination) series, the GE DS200TBQAG1A serves as a critical interface between field devices (sensors, actuators, transducers) and the Mark V controller, enabling precise signal conditioning, transmission, and isolation in harsh operational environments.

Engineered to handle analog inputs (e.g., thermocouples, RTDs) and discrete digital signals, the GE DS200TBQAG1A ensures compatibility with core Mark V modules like the DS200TCCAG1B (analog I/O) and DS200TCEAG1B (power supply). Its dual 90-pin terminal blocks support up to 180 signal connections, while configurable jumpers allow field technicians to scale voltage/current inputs without hardware modifications. The module’s 20-pin connectors (JGR, JHR, JGS/T) facilitate secure communication with the Mark V controller, ensuring real-time data exchange for turbine speed regulation, fuel control, and safety interlocks.

Built with industrial-grade components and a multilayer PCB design, the GE DS200TBQAG1A delivers robust immunity to electromagnetic interference (EMI) and high vibration, making it ideal for turbine halls, offshore platforms, and other extreme environments. With 250 V continuous isolation and a wide -40°C to +85°C operating range, this module ensures stable performance in mission-critical applications where downtime is costly.

Technical Specifications

Main Features and Advantages
The GE DS200TBQAG1A stands out for its versatility and ruggedness, offering field-proven solutions for complex turbine control systems. Its dual 90-pin terminal blocks simplify wiring by consolidating analog and digital signals into a single module, reducing panel space and installation complexity. The configurable jumpers allow technicians to adapt the module to diverse field devices—such as thermocouples (K-type, J-type) or pressure transducers (0–10 V)—without replacing hardware, enhancing flexibility in retrofit projects.

Reliability is a cornerstone of the GE DS200TBQAG1A: its 250 V isolation prevents ground loops and signal degradation, while test points enable quick diagnostics without disconnecting field wiring. The module’s hot-swap capability further minimizes downtime, allowing replacement of faulty units without powering down the entire Mark V system—a critical feature for 24/7 operations.

Engineered for extreme conditions, the GE DS200TBQAG1A incorporates IP65-rated dust and moisture resistance and a vibration-resistant design, ensuring consistent performance in high-noise environments. Its removable connectors and color-coded terminal labels streamline maintenance, while GE’s Proficy software supports remote calibration and monitoring, optimizing system efficiency.

Application Areas
The GE DS200TBQAG1A is widely deployed in gas and steam turbine control systems, where it interfaces with critical components like:

• Thermocouplesand RTDs to monitor turbine inlet/exhaust temperatures and prevent overheating.
• Vibration transducersand proximity probes to detect shaft misalignment or bearing wear.
• Fuel flow metersand pressure transmitters to regulate fuel delivery during start-up, load changes, and shutdowns.
• Solenoid valvesand limit switches for safety interlocks and emergency shutdowns.

Beyond turbines, the module excels in process automation for refineries, chemical plants, and power generation facilities. It connects level sensors and pH probes to the Mark V controller for precise process monitoring and drives discrete outputs to control pumps, compressors, and other auxiliary equipment. By integrating with GE’s Speedtronic system, the GE DS200TBQAG1A enables centralized control and diagnostics, reducing operational costs and improving system responsiveness.
