IS200TGNAH1A – Turbine-Generator Terminal Board

The IS200TGNAH1A is a turbine-generator terminal board engineered for use in GE Mark VIe control systems. It acts as the critical interface between turbine-generator field devices and the control electronics, enabling accurate data exchange for monitoring, protection, and operational control.

Designed to process a variety of input and output signals, the IS200TGNAH1A handles connections from sensors, actuators, and protection circuits associated with turbine-generator operations. These may include voltage and current transformers, protection relays, status contacts, and control outputs. With channel-to-channel galvanic isolation, it ensures that the control system is protected from electrical noise, surges, and grounding issues commonly found in industrial environments.

The board incorporates built-in LED indicators to display status and health information for each channel, allowing operators and maintenance personnel to quickly diagnose potential faults or verify correct operation. Its hot-swappable and field-replaceable design makes it possible to replace the board without halting turbine operations, minimizing downtime and increasing plant availability.

Constructed from rugged industrial-grade materials, the IS200TGNAH1A withstands vibration, temperature extremes, and electrical interference. This durability makes it suitable for installation in gas turbines, steam turbines, and combined-cycle power generation facilities.

Seamlessly integrating with GE Mark VIe control hardware, the IS200TGNAH1A supports both simplex and redundant configurations, offering flexibility to meet varying system reliability requirements. By ensuring accurate and noise-free transmission of field signals, it plays a key role in protecting turbine-generators, optimizing performance, and maintaining operational safety.

Whether deployed in power generation plants, oil & gas installations, or heavy industrial applications, the IS200TGNAH1A delivers the performance, reliability, and maintainability demanded by modern turbine-generator systems.
