Description
GE DS200TCTGG1AFF
Technical Specifications
- Part Number: DS200TCTGG1AFF
- Product Type: Thermocouple Input Board
- System Compatibility: GE Mark V Speedtronic Control System
- Input Type: Type K, J, E, or T Thermocouples (configurable)
Functional Features
- High-Channel Density: Supports multiple thermocouple inputs on a single board to monitor exhaust temperature spreads.
- Cold Junction Compensation: Provides precise internal cold junction compensation to ensure accurate temperature readings.
- Signal Filtering: Integrates hardware filtering to reject electrical noise common in turbine environments.
Application Scenarios
Gas and steam turbine exhaust temperature monitoring, combustion zone profiling, and thermal protection systems.
Performance Parameters
- Measurement Accuracy: High-precision temperature conversion with minimal drift.
- Scan Rate: Fast sampling rate to detect rapid temperature transients.
Material Composition
Industrial-grade PCB populated with precision analog front-end ICs, isolation amplifiers, and robust terminal connectors.
Structural Characteristics
Standard Mark V board form factor with high-density backplane connectors and front-panel terminal blocks for field wiring.
Working Principle
Low-level millivolt signals from thermocouples are amplified, filtered, and compensated for cold junction temperature, then converted to digital values for the Mark V processor to calculate exhaust temperature spreads and trigger alarms.
Installation Requirements
- Install in the designated I/O slot in the Mark V rack.
- Use properly shielded thermocouple extension wires.
- Ground shields at the panel only to prevent ground loops.
Usage Precautions
- Verify thermocouple type and polarity before connecting.
- Never apply external voltage to thermocouple input terminals.
- Handle with strict ESD precautions.
