Description
The GE IS200TTURH1CED (TTURH1C) is a specific Termination Board designed for the Mark VIe distributed control system. It serves as the physical interface between the field wiring and the control hardware, specifically tailored for turbine control applications. The “TTUR” designation signifies its primary usage in turbine monitoring and control loops, facilitating high-density signal termination for critical inputs like speed sensors, valve feedback, and temperature monitoring.

🚀 Integration and Application
The TTUR board is a foundational piece of the Mark VIe I/O cabinet architecture. Key integration points include:
- I/O Packs: Interfaces directly with specific Mark VIe I/O packs that plug into the board to process the incoming field signals.
- Turbine Sensors: Commonly used to terminate Magnetic Pickups (MPUs) for speed sensing, LVDT/RVDT feedback for valve position, and thermocouple inputs for exhaust gas temperature.
- Cabinet Wiring: Facilitates the organized transition from heavy-gauge field cables to the backplane-compatible signal path.
- Shield Grounding: Includes integrated grounding bars to help mitigate EMI/RFI noise, which is critical for sensitive analog turbine signals.
⚠️ Installation and Maintenance Note
Because this board handles safety-critical signals, follow these guidelines during replacement:
- Part Number Verification: The revision code (e.g., “CED”) is vital. Always ensure that the board revision is compatible with the I/O pack firmware currently in use.
- Static Precautions: This board contains sensitive signal-conditioning components. Always wear a grounded ESD wrist strap before handling.
- Loop Integrity: Before reconnecting field wires, verify that the field wiring has not been compromised by vibration or heat, as the TTUR board is often mounted in environments where mechanical stress is common.
- ToolboxST Mapping: After installation, use ToolboxST to verify that the board is communicating correctly with the controller and that all analog/digital values are being mapped properly to your control logic.
