Description
DS200DTBAG1AAA: Product Overview
The GE DS200DTBAG1AAA is a digital contact terminal board designed for integration into GE’s Mark V series of turbine control systems. As a key component of the Mark V ecosystem, it enables reliable signal transmission between digital field devices (e.g., sensors, actuators) and the turbine control unit, ensuring precise monitoring and control of turbine operations.
Role in Automation Systems:
Positioned as a “field interface” in the Mark V architecture, the DS200DTBAG1AAA performs two primary functions:
-
Digital Signal Acquisition: Receives digital input signals (e.g., from a limit switch indicating a valve is open) from field devices and transmits them to the Mark V controller for processing.
-
Relay Output Control: Sends control commands from the Mark V controller to field actuators (e.g., starting a pump, opening a valve) via relay outputs.
Core Functionality:
-
Digital Input Handling: Supports 16 channels of 24 V DC dry contact inputs, suitable for a wide range of digital sensors (e.g., proximity switches, pushbutton stations).
-
Relay Output Control: Provides 8 SPDT (single-pole double-throw) relay outputs with a maximum current rating of 5 A/250 V AC, enabling control of high-power actuators.
-
Communication: Transmits processed digital signals to the Mark V controller via the 3PL data bus, ensuring real-time communication for turbine control.
Platform Benefits (Mark V Series):
The DS200DTBAG1AAA 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 components, reducing setup time and effort.

Core Features & Customer Value
1. Reliable Digital Signal Acquisition:
The DS200DTBAG1AAA’s 16 digital input channels provide reliable signal acquisition from field devices, even in electrically noisy environments. For example, in a gas turbine, the module can monitor the status of a turbine’s emergency stop button, ensuring that the turbine shuts down safely if the button is pressed.
2. Flexible Relay Output Control:
The 8 relay outputs allow engineers to control a variety of actuators, from small relays to large valves. For instance, in a power plant, the module can start a cooling pump by sending a signal to a relay, ensuring that the turbine operates within safe temperature limits.
3. Rugged Industrial Design:
The board’s operating temperature range (-20°C to +60°C) and compact form factor make it suitable for harsh turbine hall environments. Its panel mount design simplifies installation in crowded control cabinets, reducing setup time and effort.
4. Seamless Integration with Mark V:
Designed specifically for GE’s Mark V series, the DS200DTBAG1AAA integrates with existing turbine control systems without requiring custom configuration. This reduces setup time and ensures compatibility with legacy systems, which is critical for power plants and industrial facilities.
Typical Applications
The GE DS200DTBAG1AAA is widely used in turbine control systems for:
-
Power Generation:
-
Monitors the status of turbine components (e.g., emergency stop buttons, valve position switches) in gas/steam turbines.
-
Example: In a combined-cycle power plant, the module monitors the status of a gas turbine’s inlet guide vanes, enabling the DCS to adjust the vanes for optimal efficiency.
-
-
Industrial Automation:
-
Controls actuators (e.g., valves, pumps) in industrial automation systems, ensuring precise process control.
-
Example: In a chemical plant, the module controls the opening and closing of a reactor valve based on temperature sensor inputs.
-
-
Manufacturing:
-
Monitors the status of conveyor belts, robotic arms, and other equipment in manufacturing plants.
-
Example: In an automotive plant, the module monitors the status of a conveyor belt’s limit switch, ensuring that parts are delivered to the assembly line in time.
