Common Applications
Product Precautions
The IS200TTURH1B forms the field-wiring boundary for the Mark VI primary turbine-protection chain, keeping speed, synchronization and shaft-monitoring signals organized before they reach VTUR.
- Receives passive pulse-rate speed-sensor wiring for turbine-speed measurement and primary overspeed protection.
- Terminates generator and bus potential-transformer inputs used by the automatic synchronization functions.
- Carries shaft-voltage and shaft-current monitoring signals into the primary protection subsystem.
- Connects to the VTUR processor through the documented Mark VI protection-board cabling arrangement.
TTUR keeps magnetic speed inputs, generator and bus PT circuits, shaft monitoring and VTUR cabling inside one controlled primary-protection boundary.
Important Notice: Confirm IS200TTURH1B, the installed VTUR and trip-board architecture, all terminal assignments and the simplex or TMR cabling arrangement before installation.

GE IS200TTURH1B Technical Reference (PDF)GE IS200TTURH1B Installation & Commissioning Guide (PDF)
The technical reference consolidates product identity and interface data; the installation guide provides separate readiness, configuration, verification and handover checks.
Primary overspeed inputs
Terminates passive magnetic pickup circuits used by VTUR for turbine-speed protection.
Automatic synchronization
Carries generator and bus potential-transformer inputs used by synchronization functions.
Shaft monitoring
Routes shaft-voltage and shaft-current measurement circuits into the primary protection subsystem.
Simplex or TMR integration
Supports the documented VTUR cabling arrangement selected for the installed redundancy architecture.
Read the applicable product and site instructions before work. Verify IS200TTURH1B, the installed host and every connected interface before isolation or replacement.
1
Confirm the IS200TTURH1B revision, VTUR processor and installed primary-trip-board arrangement.
2
Record every magnetic pickup, PT, shaft-monitoring and breaker-related terminal before isolation.
3
Capture the simplex or TMR cable map, including each JR, JS and JT connector used by the position.
4
Place the turbine and generator-breaker circuits in the approved maintenance state.
5
Protect keyed connectors, terminal-block labels and chassis-ground shield terminations during handling.
6
Restore pickup polarity, PT phase, shaft circuits, jumpers and relay wiring exactly as documented.
7
Review VTUR diagnostics, measured speed, PT values and synchronization permissives after energization.
8
Perform the controlled primary-trip and synchronization checks before service handover.
Technical notes
Verify the complete IS200TTURH1B revision, associated VTUR processor, terminal assignments, speed-sensor polarity, PT wiring, shaft-monitoring circuits and protection-system redundancy before removal or return to service.
