Description

Product Overview

The IS200TTURH1CFD Primary Turbine Protection Input Terminal Board by GE is engineered for high-reliability turbine control. It integrates seamlessly with VTUR, PTUR, and YTUR I/O packs, enabling precise speed and voltage monitoring. This board supports 12 pulse rate sensors and delivers 125 Vdc to the main breaker coil for automatic synchronizing.

Three onboard relays—K25, K25P, and K25A—must close simultaneously to energize breaker 52G. The board routes signals via PR3 and JR4 connectors in simplex systems, and expands to PR3, PS3, PT3, JR4, JS4, and JT4 in TMR configurations.

Application & Compatibility

The IS200TTURH1CFD board is compatible with GE’s Mark VIe control systems. It supports TRPG, TRPS, and TRPA boards, along with the PTUR I/O pack. For safety-certified environments, use TTURS1C. Note: TTURH1C is not suitable for Mark VI systems—use TTURH1B instead.

This board is ideal for turbine speed sensing, shaft voltage/current monitoring, and overspeed trip signal routing. It ensures robust protection and control in high-performance turbine applications.
