🔧 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.
