Product details
🌐 Overview
The GE IS200TTURH1C termination board is a high-performance synchronization module designed for Speedtronic Mark VI and Mark VIe turbine control systems. It ensures accurate phase and speed alignment between generators, enabling reliable operation in gas and steam turbines.
Engineered for industrial robustness, the board includes D-shell connectors, dual center transformers, and heavy-duty screw terminal blocks that guarantee stable and interference-free signal transmission.
⚙️ Key Features
- Manufacturer: General Electric
- Model: IS200TTURH1C
- Series: Mark VI / Mark VIe
- Function: Termination / terminal board for turbine control and synchronization tasks
- Connectivity: D-shell male and female connectors, plug connectors, and two numbered screw terminal blocks
- Voting Modes: Two onboard jumper switches for simplex or TMR (Triple Modular Redundant) configuration
- Components: Surface relays, variable resistors, and two center transformers for signal isolation
- Environmental Tolerance: Designed for control room temperatures and electrical noise immunity
- Interfacing: Works with PTUR and VTUR daughter PCBs to process phase and speed signals
🔧 Performance & Reliability
The IS200TTURH1C board meets standard turbine synchronization and protection requirements. It employs transformer coupling and hardware isolation for strong noise immunity and uses robust mechanical relays to ensure long-term electrical reliability. Its mechanical layout and terminal design support stable field wiring connections for years of dependable operation.
🧰 Installation Guide
- Mount the IS200TTURH1C board on a grounded rack near PTUR and VTUR boards for short connector runs.
- Configure the jumper switches before applying power to select simplex or TMR mode.
- Connect D-shell and plug connectors according to mating pinouts.
- Tighten screw terminals with proper torque and label each wire.
- Perform continuity and insulation checks before first commissioning.
🔄 Compatibility
This board is fully compatible with GE Speedtronic Mark VI and Mark VIe turbine control systems. It is suitable for gas and steam turbines, particularly in combined-cycle and base-load plants requiring precise synchronization and generator protection.
🧠 Technical Notes (from Field Engineers)
- Use shielded twisted-pair cables for PTUR/VTUR signals and terminate shields at a single point.
- Always torque screw terminals per manufacturer recommendation to prevent contact resistance.
- Choose TMR voting when redundancy is essential for fault-tolerant operation.
⚡ Why Proper Voting Matters
Simplex mode provides straightforward configuration for single-channel systems, while TMR mode offers fault tolerance and improved reliability. For critical turbine plants, engineers typically recommend TMR mode to reduce false trip events and improve uptime.
📊 Example from Field Application
In a 3×350 MW combined-cycle plant, upgrading from older termination boards to the IS200TTURH1C reduced synchronization alarms by over 70%, significantly improving startup stability and generator reliability.
❓ FAQ
Q: How do I select simplex or TMR mode?
A: Use the two onboard jumper switches to set the required configuration. Follow your plant’s voting diagram for correct setup.
Q: Are transformers included on the board?
A: Yes. Two isolation transformers are mounted near the center of the board for signal conditioning.
Q: Which connectors should I use for wiring?
A: Use the D-shell connectors for module connections and the two numbered screw terminal blocks for field wiring.
