Description
GE DS3800NRTB1A1A
Technical Specifications
- Product Line: GE Speedtronic Mark IV.
- Part Number: DS3800NRTB1A1A.
- Board Type: Turbine Control / Relay / Interface Board.
- Suffix: 1A1A (Indicates specific hardware revision).
Functional Features
- Signal Processing: Accurately conditions analog and digital signals from turbine sensors.
- Actuator Control: Drives external relays and actuators for precise turbine speed and load management.
- Fault Tolerance: Designed to operate reliably within redundant control architectures.
- Diagnostics: Features onboard indicators for rapid troubleshooting.
Application Scenarios
Exclusively deployed in power generation plants, petrochemical facilities, and industrial cogeneration systems utilizing GE turbines.
Performance Parameters
- Response Time: Millisecond-level processing for critical safety and control functions.
- Signal Accuracy: High-precision analog processing.
- Environmental Tolerance: Ruggedized to withstand high temperatures and EMI in turbine enclosures.
Material Composition
Multi-layer industrial PCB with heavy conformal coating to protect against moisture, sulfur, and conductive dust. Features gold-plated backplane connectors.
Structural Characteristics
Standard Eurocard form factor with front panel test points, configuration jumpers, status LEDs, and a precision edge connector for rack integration.
Working Principle
Receives raw field signals, conditions and scales them, and routes the data to the central Mark IV processor. It also receives control commands from the processor and energizes output relays to control turbine valves and auxiliaries.
Installation Requirements
Must be inserted into an active Mark IV control rack. Handle strictly by the edges to prevent bending or damaging backplane pins.
Usage Precautions
Never hot-swap the board. Always de-energize the control rack before installation. Verify that the suffix matches the system requirements exactly.
