Description
GE IS200TTURH1CDC – Turbine Termination Input/Output Board
Product Overview
The GE IS200TTURH1CDC is a high-reliability Turbine Termination Board designed for the Mark VI and Mark VIe Speedtronic™ control systems. This module serves as the primary interface between the turbine’s field sensors and the controller’s I/O processors. Its fundamental role is to consolidate and route critical signals—specifically those related to turbine speed monitoring, flame detection, and shaft voltage—ensuring that the control system receives clean, accurate data for real-time decision-making.
In a gas or steam turbine environment, the IS200TTURH1CDC acts as a robust junction point. It simplifies field wiring by providing dedicated terminal blocks for magnetic pickups and flame sensors, while also incorporating protective circuitry to prevent electrical noise or surges from reaching the sensitive control processors. As a “C” revision (CDC variant), this board features updated hardware components for improved longevity and signal stability in harsh industrial conditions.

Key Features & Benefits
- High-Density Speed Monitoring: Supports up to 12 magnetic pickup inputs, allowing for redundant speed sensing to prevent false trips or undetected overspeed conditions.
- Passive Signal Routing: As a termination board, it uses passive components to route signals, which inherently increases system reliability by reducing the number of active failure points between the field and the processor.
- Flame Detector Integration: Features specialized circuitry to handle inputs from ultraviolet or intensity-based flame sensors, which are critical for “Loss of Flame” safety logic in gas turbines.
- Redundancy Support: Designed to work in Simplex, Dual, or TMR (Triple Modular Redundant) configurations, providing the flexibility needed for different safety integrity levels (SIL).
Application Scenarios
- Gas Turbine Power Plants: Used in GE Frame 6, 7, and 9 turbines to monitor rotor speed and combustion stability through flame sensor feedback.
- Steam Turbine Control: Provides shaft voltage monitoring and speed sensing for large-scale steam turbines used in nuclear or fossil fuel power generation.
- Mechanical Drive Applications: Deployed in large-scale LNG (Liquefied Natural Gas) facilities where turbines drive massive compressors and require fail-safe speed monitoring.
Frequently Asked Questions (FAQ)
- Q: What is the primary function of the IS200TTURH1CDC?
- A: It is a termination board that collects speed (MPU) and flame detection signals from the turbine and transmits them to the Mark VI/VIe I/O processors.
- Q: Is IS200TTURH1CDC compatible with legacy systems?
- A: This board is specifically designed for the Mark VI and Mark VIe platforms. While it shares functions with older Mark V systems, it is not pin-for-pin compatible without the corresponding control architecture.
- Q: Does the “CDC” suffix indicate a specific version?
- A: Yes, the “CDC” suffix refers to the specific revision and group of the board. It typically denotes the hardware version and the specific coating or component set used during manufacturing for that model group.
