GE Electric | DS200SI0CG1AEA | High-Density Analog Input/Output Module

Key Features

• Versatile I/O Support:
  Supports a wide range of analog signal types on a single module, including mA, Voltage (V), RTD, and Thermocouple (TC) inputs.

• High Accuracy:
  Delivers 16-bit resolution for precise and reliable process monitoring in critical turbine applications.

• Galvanic Isolation:
  Electrically isolates signal channels to protect control systems from ground loops and transient disturbances.

• Hot-Swap Capable:
  Modules can be replaced without system shutdown in redundant turbine configurations, ensuring continuous operation.

• On-board Diagnostics:
  Provides real-time fault detection, including open wire and out-of-range signal alerts, improving system reliability and response time.

• EMC/RFI Immunity:
  Built to operate reliably in electrically noisy environments typical of power generation facilities.

Primary Function & Purpose

This module is designed to:

• Input: Convert field analog signals into digital data used by the turbine control logic.

• Output: Translate digital controller commands into analog signals for field actuators.

It plays a vital role in maintaining precision, stability, and safety within critical process control loops, such as:

• Fuel flow regulation

• Temperature control

• Pressure monitoring

Typical Applications & Use Cases

Process Monitoring:

• Turbine inlet temperature (via thermocouples)

• Lube oil pressure (from 4–20mA transmitters)

• Vibration signals (using ±10VDC sensors)

Control Outputs:

• Governor valve position control (through 4–20mA to I/P converters)

• Inlet guide vane positioning (0–10VDC control)

Protection Systems:

• Exhaust over-temperature protection (RTD inputs)

• Hydraulic system pressure feedback
