GE Electric | DS200FSAAG2ABA | Field Sense Assembly (FSA) module
Product Description:
The GE DS200FSAAG2ABA is a Field Sense Assembly (FSA) module designed for GE’s Mark V Speedtronic gas/steam turbine control system. It serves as a field termination interface, acquiring, conditioning, isolating, and digitizing analog signals (e.g., voltage, current, RTDs, thermocouples) and digital status inputs from field sensors. The “G2” variant features integrated terminal blocks for direct field wiring, simplifying installation and maintenance compared to connector-based FSAs.

Features:
- Integrated Terminal Blocks: Enables direct field wiring without external connectors or adapter boards.
- Multi-Signal Support: Configurable per channel for voltage, mA, RTD, TC, or digital inputs.
- High Electrical Isolation: Protects sensitive control logic from field-side transients/noise.
- Signal Conditioning: Amplification, filtering, linearization, cold-junction compensation (T/Cs), and excitation (RTDs).
- On-Board Diagnostics: Real-time monitoring for sensor faults (open/short/out-of-range).
- Hot-Swap Capability: Replaceable without full system shutdown (requires following safety protocols).
- VME Bus Interface: High-speed communication with Mark V controller.
- Rugged Design: Built for harsh industrial environments (vibration, temperature).
Function/Role:
Acts as the primary I/O interface between field instrumentation (sensors/transmitters) and the Mark V controller. It converts raw analog/digital signals into isolated, high-accuracy digital data for turbine control and protection algorithms.
Purpose:
To reliably acquire critical process variables (temperature, pressure, flow, vibration, valve position) while providing electrical isolation, noise immunity, and diagnostic capabilities for safe turbine operation.
Applications & Use Cases:
- Gas/Steam Turbine Monitoring: Bearing temperatures, exhaust temp, fuel pressure, valve feedback.
- Generator Protection: Winding/bearing RTDs, hydrogen cooler temps, seal oil pressure.
- Auxiliary Systems: Lube oil temp/pressure, cooling water flow, filter differential pressure.
- Process Control: Analog loop monitoring (e.g., inlet guide vane position).
- Status Indication: Digital inputs (pump running, breaker status).
Application Fields:
- Power Generation Plants (Combined-Cycle, Simple-Cycle, Cogeneration)
- Oil & Gas (Compressor stations, offshore platforms)
- Industrial Facilities (Petrochemical, Pulp & Paper, Manufacturing)
- District Energy Systems
