Description
The GE IS200TTURH1CED (often referred to as the TTUR Terminal Board) is a critical I/O termination board used within the GE Mark VI and Mark VIe turbine control systems. It serves as a physical interface between field-mounted instrumentation—specifically turbine-related sensors—and the control system’s processor modules. The “H1C” designation identifies it as a standard turbine control termination board designed for high-density, reliable signal routing.

Key Applications & Connectivity ⚙️
The TTUR board is specifically engineered to handle the high-speed and sensitive signals required for turbine protection and control. It typically interacts with:
- Speed Inputs: Magnetic Pickups (MPUs) or proximity sensors used to monitor turbine rotor speed (shaft speed).
- Vibration Monitoring: Interfaces with sensors that provide real-time data on turbine seismic and radial vibration.
- Synchronous/Pulse Inputs: High-frequency signal processing for precise speed measurement.

To ensure the board functions correctly, it is usually paired with the following Mark VI/VIe modules:
- IS215VPROH1B (VPRO Protection Module – primary partner for TTUR)
- IS215VTURH1C (VTUR Turbine Control Module)
- IS200TRLYH1B (Relay Output Terminal Board)
- IS200STCIH1A (Bridge Interface Board)
- IS200TREGH1B (Turbine Control I/O Module)

- IS200WROBH1A (Relay Output Board)
Maintenance & Troubleshooting Notes ⚠️
- Revision Compatibility: When replacing an FA/00 revision board, verify if your system architecture allows for newer revisions (e.g., later versions of the H1C series). In many cases, these are backward compatible, but system-wide software configurations might need an update to reflect the hardware change.
- Sensor Wiring: Because the TTUR board handles sensitive speed and vibration signals, ensure that all shielded cables are properly terminated to the board’s chassis ground to prevent EMI/RFI noise from corrupting turbine control logic.
- LED Status: The board features diagnostic LEDs to indicate power and communication health; if a channel LED is off, verify the integrity of the field sensor loop before replacing the board itself.
