Description
DS200TBQDG1AFE: Product Overview
The GE DS200TBQDG1AFE is an analog input termination module designed specifically for GE Speedtronic™ Mark V distributed control systems (DCS), the industry standard for gas, steam, and hydro turbine control in power generation. As part of the Mark V ecosystem, it acts as a “signal gateway” between field devices (e.g., temperature probes, pressure transducers, current sensors) and the turbine control unit. Its primary role is to terminate and condition analog signals—converting raw signals from field devices into a format suitable for the control unit—ensuring reliable data transmission for turbine stability and efficiency.
Engineered for the demanding conditions of turbine halls, the DS200TBQDG1AFE features a robust rail-mounted design and high-precision signal processing to withstand vibration, dust, and electromagnetic interference (EMI). Its legacy compatibility makes it ideal for retrofitting aging Mark V systems—common in power plants operating turbines for 20+ years—where replacing the entire control architecture is cost-prohibitive. Whether used in 7EA gas turbines or 9F steam turbines, the DS200TBQDG1AFE ensures accurate signal termination, directly extending the operational life of critical turbine control systems.
Role in Automation Systems
Positioned as a “field-to-controller signal interface” in Mark V architectures, the DS200TBQDG1AFE performs two key functions:
-
Signal Termination: Receives analog signals from field devices (e.g., a thermocouple measuring turbine exhaust temperature) and terminates them into the module’s input channels.
-
Signal Conditioning: Scales and conditions the raw signals (e.g., converting millivolt signals to 4–20 mA current loops) to match the input requirements of the turbine control unit. This ensures the control unit receives accurate data for processing (e.g., adjusting fuel flow based on temperature readings).
Its core value lies in bridging the gap between field devices and the control unit—a critical step in maintaining turbine stability, as even minor signal inaccuracies can lead to process instability (e.g., turbine speed variations) or equipment damage (e.g., excitation system failure).
Core Functionality
-
High-Precision Signal Processing: The DS200TBQDG1AFE offers ±0.1% input accuracy, ensuring that the turbine control unit receives precise data from field devices. This is critical for applications like turbine exhaust temperature monitoring, where small deviations can impact fuel efficiency and emissions.
-
Flexible Input Ranges: Supports customizable input ranges (e.g., 0–10 V DC, 4–20 mA) to accommodate diverse field devices. This flexibility reduces the need for additional signal conditioning hardware, saving time and money during installation.
-
Rugged Industrial Design: The module’s rail-mounted design and industrial-grade components (e.g., robust PCB coating) protect against dust, moisture, and vibration—common in turbine hall environments. The operating temperature range (-40°C to +85°C) ensures reliable operation in extreme climates.
-
Easy Integration: Compatible with existing Mark V components (e.g., I/O racks, controllers), the DS200TBQDG1AFE fits into standard Mark V control cabinets without major modifications. This minimizes installation time and cost, making it ideal for retrofit projects.

Core Features & Customer Value
1. Reliable Signal Termination:
The DS200TBQDG1AFE’s high-precision signal processing ensures that the turbine control unit receives accurate data from field devices. For example, in a power plant, the module can precisely terminate the signal from a turbine exhaust temperature sensor, allowing the control unit to adjust fuel flow and maintain optimal efficiency.
2. Flexible Configuration:
Customizable input ranges allow engineers to adapt the module to different field devices, reducing the need for additional signal conditioning hardware. This flexibility saves time and money during installation, especially in retrofit projects.
3. Rugged Industrial Design:
The module’s rail-mounted design and industrial-grade components ensure reliable operation in harsh environments. For example, in a turbine hall, the DS200TBQDG1AFE can withstand vibration from nearby turbines and electromagnetic interference (EMI) from high-voltage equipment.
4. Easy Integration:
Compatibility with existing Mark V components minimizes installation time and cost. The rail-mounted design simplifies integration into standard Mark V control cabinets, making it ideal for retrofit projects.
