GE Electric | DS200SI0CG1AEA | High-Density Analog Input/Output Module
Product Description:
The GE DS200SIOCG1AEA is a High-Density Analog Input/Output Module for Speedtronic Mark V turbine control systems. It provides bidirectional signal conditioning between field sensors/actuators and the Mark V controller, handling analog voltage/current inputs (e.g., temperature, pressure) and outputs (e.g., valve control signals) with precision conversion, isolation, and diagnostics.

Key Features:
- Versatile I/O Support: Handles diverse analog signals (mA, V, RTD, TC) on a single module.
- High Accuracy: 16-bit resolution for critical process monitoring.
- Galvanic Isolation: Protects control systems from ground loops/transients.
- Hot-Swap Capable: Replaceable without shutting down the turbine (redundant systems).
- On-board Diagnostics: Real-time fault detection (open wire, out-of-range).
- EMC/RFI Immunity: Designed for electrically noisy power plant environments.
Primary Function & Purpose:
Converts field analog signals to digital data for turbine control logic (inputs) and translates controller commands to analog outputs for actuator control (outputs). Ensures precision, stability, and safety in critical loops (e.g., fuel flow, temperature control).
Typical Applications & Use Cases:
- Process Monitoring:
- Turbine inlet temperature (thermocouples).
- Lube oil pressure (4–20mA transmitters).
- Vibration sensor signals (±10VDC).
- Control Outputs:
- Governor valve position (4–20mA to I/P converters).
- Inlet guide vane control (0–10VDC).
- Protection Systems:
- Exhaust over-temperature (RTD inputs).
- Hydraulic pressure feedback.
Application Field:
Deployed in turbine control and protection systems across:
- Power Generation: Combined-cycle plants (CCPP), gas/steam turbines.
- Oil & Gas: Turbine-driven compressors/pumps.
- Marine: Naval propulsion control.
- Industrial: Cogeneration facilities, compressor stations.
