Description

DS200UPLAG1B: Product Overview​
The GE DS200UPLAG1B​ is an RST extended analog terminal board designed for integration into GE’s Mark V series​ of turbine control systems. As a critical component of the Mark V ecosystem, it enables extended analog signal termination and conditioning for field devices (e.g., LVDT position sensors, thermocouples, pressure transmitters) and communicates processed signals to the Mark V controller.
Role in Automation Systems:
Positioned as an “extended signal interface” in the Mark V architecture, the DS200UPLAG1B performs two primary functions:
  1. Signal Termination: Provides additional analog input/output (I/O) channels to support growing system demands (e.g., adding more sensors or actuators in a turbine control system).
  2. Signal Conditioning: Filters, amplifies, and scales raw analog signals from field devices to ensure accuracy and consistency before transmitting them to the Mark V controller.
Core Functionality:
  • Extended Signal Support: Builds on the capabilities of standard Mark V analog I/O boards (e.g., TCQA) by adding more channels for LVDT, thermocouple, 4–20 mA, and voltage signals.
  • Hardware Configuration: Uses jumpers (e.g., J1–J8) to select signal types, configure output ranges (e.g., 4–20 mA vs. 0–20 mA), and enable test modes (e.g., RS232 port for card testing).
  • Communication: Transmits processed signals to the Mark V controller via the 3PL data bus and exchanges generator/line signals with other I/O boards (e.g., TCQC) via the JE connector.
Platform Benefits (Mark V Series):
The DS200UPLAG1B leverages GE’s Mark V platform, which is renowned for:
  • Reliability: Industrial-grade components and a rugged design ensure 24/7 operation in harsh turbine hall environments (e.g., high temperature, vibration).
  • Scalability: Supports expansion with additional terminal boards to accommodate growing system demands (e.g., adding more sensors or actuators).
  • Integration: Seamlessly integrates with Mark V controllers and other I/O cores (R1, R2, R3), reducing setup time and effort.

Core Features & Customer Value​
1. Extended Signal Capacity:
The DS200UPLAG1B provides additional analog I/O channels beyond standard Mark V boards, allowing engineers to expand system capabilities without replacing existing hardware. For example, in a gas turbine control system, this means adding more LVDT sensors to monitor blade positions or thermocouples to measure exhaust gas temperature, improving control precision.
2. Flexible Configuration:
Hardware jumpers enable customization of signal types and output ranges, reducing the need for software changes. For instance, configuring the milliamp output range (20 mA vs. 200 mA) via J5/J6 allows the board to interface with different actuators (e.g., small valves vs. large pumps), saving time and money during installation.
3. Reliable Communication:
The 3PL data bus and JE connector ensure seamless communication with other Mark V components, minimizing latency and ensuring real-time signal transmission. This reliability is critical for turbine control, where delayed signals could lead to equipment damage or downtime.
4. Rugged Design:
The board’s operating temperature range (-40°C to +70°C) and compact form factor make it suitable for harsh turbine hall environments. Its DIN rail mounting option simplifies installation in crowded control cabinets, reducing setup time and effort.
Typical Applications​
The GE DS200UPLAG1B​ is widely used in gas turbine control systems for:
  1. Turbine Blade Position Monitoring:
    • Uses LVDT inputs to measure the position of turbine blades, enabling the Mark V controller to adjust blade angles for optimal efficiency.
  2. Exhaust Gas Temperature Measurement:
    • Uses thermocouple inputs to monitor exhaust gas temperature, helping to prevent overheating and optimize combustion.
  3. Pressure/Flow Control:
    • Uses 4–20 mA inputs to measure pressure and flow rates in fuel lines, enabling the controller to adjust fuel flow for consistent turbine output.
  4. Generator/Line Signal Exchange:
    • Uses the JE connector to exchange generator and line signals with other I/O boards (e.g., TCQC), supporting grid synchronization and power output control.
