Description
DS200CPCAG1ABB: Product Overview
The GE DS200CPCAG1ABB is a contactor pilot board designed specifically for GE Mark V gas turbine control systems, a flagship platform for industrial power generation and turbine automation. As part of the Mark V ecosystem, it plays a pivotal role in regulating the excitation system—critical for maintaining turbine stability and power output.
Role in Automation Systems:
Positioned as a “contactor control hub” in Mark V architectures, the DS200CPCAG1ABB performs two primary functions:
-
Voltage Conversion: Transforms incoming 115 V AC (from the turbine’s power supply) into 105 V DC, which is required to energize the contactor coils. This conversion ensures that contactors operate reliably under varying load conditions.
-
Contactor Activation: Sends control signals to contactors, dictating when to open or close based on commands from the turbine’s main controller. For example, when the turbine starts, the DS200CPCAG1ABB activates contactors to connect the generator to the grid.
Core Functionality:
-
Precision Voltage Regulation: The board’s circuitry maintains a stable 105 V DC output, even with fluctuations in the input AC voltage. This stability is critical for preventing contactor chatter (rapid opening/closing), which can damage turbine components.
-
Flexible Connectivity: The 12-pin and 2-pin connectors allow seamless integration with the Mark V system’s backplane, while the four terminal blocks support up to 12 signal wires—enabling connection to multiple contactors and sensors.
-
24 V DC Power Relay: A built-in relay provides auxiliary power to the contactor coils, ensuring that the board can handle high-current loads without overheating.
-
Robust Design: Constructed with industrial-grade components, the DS200CPCAG1ABB withstands harsh environments (e.g., high temperature, vibration) commonly found in turbine halls.
