Product Overview
Turbine overspeed protection is structured into three tiers: control, primary, and emergency. The IS200VTURH1B serves as a core component in the primary protection layer, working with the VTUR I/O board and TTUR terminal board to process shaft speed signals. These signals are median-selected by the controller, and upon detecting a trip condition, the card transmits a trip signal to the TRPG terminal board. Through a 2/3 voting mechanism across three relay circuits (one per trip solenoid), it ensures rapid de-energization of solenoids, stopping the turbine safely.
This integration with GE’s Mark VI system makes the IS200VTURH1B a trusted solution for industries relying on continuous turbine operation, where downtime or failures can lead to significant losses.

Features
Triple Redundancy for Reliability
The IS200VTURH1B operates within a redundant architecture, ensuring no single point of failure. It works alongside three independent VTUR outputs, each monitored and voted on to prevent false trips—critical for maintaining turbine uptime.
Software-Free Voting for Independence
Unlike systems relying on software-based logic, this card uses hardware-driven 2/3 voting in relay circuits. This design eliminates software-related delays or errors, making the protection mechanism faster and more reliable, especially in high-stakes operational environments.
Seamless Integration with GE Ecosystems
It integrates seamlessly with GE’s Mark VI control components, including the TTUR terminal board (for speed signal input) and TRPG terminal board (for trip signal output). This compatibility reduces installation complexity and ensures consistent performance within GE turbine systems.
Status Transparency via IONet
The card communicates status information through an IONet cable, providing real-time insights to operators. This visibility allows for proactive monitoring and troubleshooting, minimizing unplanned downtime.
Emergency Layer Compatibility
While focusing on primary protection, the IS200VTURH1B coexists with GE’s VPRO emergency protection system. Both systems operate independently, with the VPRO using triple redundant speed signals to trigger trips—ensuring layered safety for maximum risk mitigation.
Applications
Power Generation Turbines
The IS200VTURH1B is widely used in gas and steam turbines for power plants, where maintaining stable operation is vital for grid reliability. It prevents overspeed-related failures that could disrupt electricity supply.
Industrial Turbines
In industries like oil and gas, chemical processing, and manufacturing, turbines drive critical machinery (e.g., compressors, pumps). This card protects these turbines from overspeed, safeguarding equipment and preventing production halts.
Distributed Control System (DCS) Integration
As part of GE’s Mark VI system, it integrates with larger DCS setups, such as Emerson DeltaV or Foxboro I/A Series, enabling centralized monitoring and control of turbine safety across complex industrial facilities.
Simplex System Protection
For simplex (non-redundant) turbine systems, the card enhances safety via the Servo Terminal Board (TSVO). It connects to TREG terminal boards, ensuring that critical trips force control valves closed—an extra layer of protection for simpler setups.
FAQ
Is the IS200VTURH1B compatible with GE Mark VIe systems?
While primarily designed for the Mark VI system, the IS200VTURH1B may be compatible with Mark VIe setups with proper configuration. Consult GE’s technical documentation or contact support for verification.
How quickly does the card respond to an overspeed condition?
The hardware-based 2/3 voting mechanism ensures trip signals are transmitted within milliseconds of detecting an overspeed condition, minimizing response time to prevent damage.
What is the warranty for the IS200VTURH1B?
Warranty terms vary by supplier. For this product, standard warranties typically cover 12 months from delivery, excluding damage from improper installation or misuse.
Can the card be installed by in-house technicians?
Installation requires familiarity with GE Mark VI systems and turbine safety protocols. It is recommended to use certified technicians to ensure compliance with industry standards and avoid operational risks.
How does the IS200VTURH1B differ from other GE turbine protection cards?
Its key distinction is the software-free, relay-based voting system, which offers higher reliability than software-dependent alternatives. It also integrates tightly with Mark VI components, reducing compatibility issues.
