GE IS200STCIH1A IS200STCIH1ADD Turbine Emergency Trip

The IS200STCIH1A IS200STCIH1ADD functions as an emergency trip board for gas turbines. This printed circuit board belongs to the Mark VI Speedtronic series from General Electric. The IS200STCIH1A serves as the standard version for overspeed protection. Its variant, the IS200STCIH1ADD, includes a conformal coating for enhanced circuit durability. Both boards manage emergency shutdown functions for gas turbine safety systems.

Core Technical Specifications

This board provides one emergency trip relay channel for overspeed conditions. You will also find redundant trip circuits for fail-safe operation. The board stores minimal energy but uses capacitors for contact protection. Meanwhile, the backplane interface handles all power and data transfers.
