Description
GE DS3820FDRA1B1A
Technical Specifications
- System Platform: GE Mark IV Speedtronic.
- Input Type: Analog (4-20mA, 0-10V, RTD, TC).
- Channels: Multiple isolated analog inputs.
- Resolution: High-resolution ADC.
Functional Features
- Signal Conditioning: Filters, amplifies, and scales raw sensor signals.
- Isolation: Channel-to-channel and channel-to-ground isolation.
- Diagnostics: Detects open circuits, short circuits, and out-of-range conditions.
Application Scenarios
Essential for monitoring turbine speed, temperature, pressure, and vibration in power generation.
Performance Parameters
- Accuracy: ±0.1% or better of span.
- Update Rate: Fast scanning for real-time control.
- Noise Rejection: High CMRR for noisy environments.
Material Composition
Precision analog components, isolation transformers, and conformal-coated PCB.
Structural Characteristics
Mark IV board form factor with front-panel test points and backplane connector.
Operating Principle
Analog signals are filtered, amplified, and converted to digital values by the ADC. Data is transmitted to the Mark IV processor via the backplane.
Installation Requirements
Use shielded twisted-pair cable for analog signals. Ground shields at one end only. Calibrate after installation.
Usage Precautions
Do not apply voltage beyond input rating. Verify signal type matches configuration. Handle with ESD protection.
