IS200TTURH1B
A turbine termination board used in the Mark VI control architecture for turbine speed pickup signals, shaft monitoring, generator and bus voltage sensing, and generator-breaker synchronization circuits.
Signal Interface & Control Role
How the board fits into the turbine control system
TTUR provides field termination for selected turbine-control signals and connects those circuits with the associated control and protection hardware. Its interfaces include magnetic speed pickups, shaft voltage and current monitoring, generator and bus potential-transformer inputs, and the main generator breaker close circuit.
For automatic synchronization, the generator and bus voltage signals are evaluated alongside turbine speed and synchronization logic. Breaker closure depends on the required internal relay conditions and external permissives; the terminal board alone does not determine whether the generator is ready to connect to the bus.
Technical Specifications
Board identification and system-level interface details
GE Mark VI turbine control architecture
Detailed signal, terminal and relay characteristics
The Mark VI system guide gives a pulse-rate range of 2 Hz to 14 kHz and an input sensitivity of 27 mV peak for the documented MPU interface.
The system-level specification lists 0.05% of reading for MPU pulse-rate accuracy. Confirm applicability to the installed hardware and signal path before using this value for acceptance testing.
The synchronization interface uses potential-transformer secondary signals. The documented typical nominal value is 115 V AC RMS; verify the actual plant circuit and approved wiring before testing.
The documented TTUR breaker interface uses a nominal 125 V DC breaker-coil supply. Verify the installed breaker circuit rating, wiring and isolation arrangements before maintenance.
Terminal block layout reference
| Terminal range | Signal or circuit | Identification notes |
|---|---|---|
| TB points 1–8 | Generator breaker close circuit and associated relay contacts | Includes the breaker interface and synchronization relay paths. |
| TB points 17–20 | Generator and bus voltage signals | Used by the synchronization interface. |
| TB points 21–24 | Shaft voltage and shaft current signals | Confirm the exact terminal assignment against the applicable wiring diagram. |
| TB points 25–48 | Magnetic speed pickup signal pairs | Signal pairs are allocated to the documented T, S and R paths. |
Synchronization relay logic and redundancy configuration
Works with the VTUR automatic synchronization function to provide the associated breaker-close relay condition.
Provides a permissive condition tied to the turbine control sequence and application logic.
Provides a synchronization-check relay function associated with the protection-side logic.
The documented architecture uses jumper-selectable relay driver arrangements for Simplex or TMR applications. The correct jumper positions must match the installed control configuration.
The generator breaker close circuit requires the appropriate relay conditions and external permissives. In TMR configurations, the relevant control paths use redundant controller signals and voting logic. Relay status, breaker feedback and circuit supply should be checked as separate diagnostic points.
Application & Fault Investigation
Practical checks for common turbine-control symptoms
Missing or unstable speed signal
Check the pickup device, cable condition, terminal pair, shield termination and corresponding control diagnostics. Confirm whether the issue affects one channel or multiple redundant paths before attributing the fault to the board.
Generator will not synchronize
Review generator and bus voltage measurements, frequency and phase differences, synchronization permissives, relay feedback and external interlocks. A failed close permissive does not by itself identify a defective TTUR board.
Generator breaker will not close
Check the specified breaker-coil supply, K25/K25P/K25A relay states, external permissives and 52G feedback according to the approved troubleshooting procedure. Isolate the breaker close circuit before any functional test.
Shaft signal abnormality
Inspect the sensor circuit, field wiring and signal termination, then compare the indicated measurement with the system's diagnostic data. Confirm the fault source before replacing hardware.
Documentation Reference
For technical verification and maintenance planning
The GE Mark VI Control System Guide, GEH-6421 series, covers the TTUR terminal board architecture, speed pickup inputs, synchronization relays, terminal connections and breaker-interface checks. Use the applicable volume and revision together with the plant's approved wiring diagrams to verify the installed configuration.
