IS200SRTDH2ACB GE Analog Input Terminal Board

Product Description

The IS200SRTDH2ACB is a Simplex Analog Input Terminal Board designed for GE’s Mark VI Speedtronic Turbine Control System. It serves as an interface between field sensors (e.g., RTDs, thermocouples) and the Mark VI controller. This board conditions low-level analog signals for accurate processing by the control system, ensuring reliable monitoring of temperature and other critical parameters in industrial environments.

IS200SRTDH2ACB Key Specifications & Parameters

1. Type: Simplex (non-redundant) Terminal Board.
2. Compatibility: Interfaces with SRTDO (IS200SRTDO-) Analog Input Processor modules.
3. Input Channels: 16 channels (configurable for various sensor types).
4. Supported Sensors: 
   • Resistance Temperature Detectors (RTDs): 2-wire, 3-wire, or 4-wire configurations (e.g., Pt100, Ni120).
   • Thermocouples (TCs): Types J, K, T, E, R, S, B, N.
   • Millivolt (mV) signals.
   • Dry contact closures (discrete status).
5. Signal Conditioning: Provides excitation current for RTDs, cold junction compensation (CJC) for thermocouples, and filtering.
6. Isolation: High-voltage isolation between field wiring and the control system.
7. Connections: Screw terminal blocks for field wiring.
8. Mounting: Installs directly into a Mark VI I/O pack or terminal board enclosure.
9. Series: Part of the GE Mark VI (IS200-) series for gas/steam turbine and compressor control.

Key Features

1. High Density: 16 channels per board optimize space in control cabinets.
2. Versatile Input Handling: Flexible configuration per channel for RTD, TC, mV, or dry contact.
3. Accuracy & Stability: Precision signal conditioning for reliable temperature and process monitoring.
4. Isolation: Protects sensitive control electronics from ground loops, surges, and noise in field wiring.
5. Cold Junction Compensation: Integrated CJC for accurate thermocouple readings.
6. RTD Excitation: Supplies stable current for 2-wire, 3-wire, or 4-wire RTD measurements.
7. Robust Construction: Designed for harsh industrial environments (vibration, temperature extremes).
8. Plug-and-Play: Simplified installation and replacement within the Mark VI architecture.

 Function & Purpose

• Signal Interface: Bridges passive field sensors (RTDs, TCs) to the active processing electronics (SRTDO module).
• Signal Conditioning: Converts raw sensor outputs (resistance changes, small voltages) into clean, normalized signals suitable for the controller’s analog-to-digital converters (ADCs).
• Isolation Barrier: Electrically separates potentially noisy or hazardous field wiring from the critical control system circuitry.
• Sensor Support: Provides necessary power (excitation) and compensation (CJC) for specific sensor types to operate correctly.

Applications & Use Cases

1. Gas Turbine Control: 
   • Exhaust gas temperature (EGT) monitoring via thermocouples.
   • Bearing metal temperatures via RTDs.
   • Lube oil/coolant temperatures.
2. Steam Turbine Control: 
   • Steam chest/casing metal temperatures.
   • Bearing temperatures.
   • Cooling water temperatures.
3. Compressor Control: 
   • Process gas inlet/outlet temperatures.
   • Bearing and seal temperatures.
   • Coolant temperatures.
4. Power Generation: Critical temperature monitoring in boilers, heat recovery steam generators (HRSGs), and auxiliary systems.
5. Industrial Process Control: Any application requiring high-density, reliable temperature monitoring within the Mark VI ecosystem.
