The IS200TRPGH1A module functions as a primary trip termination board within the gas turbine control system.
It interfaces with the primary turbine protection controller (VTUR or PTUR) and plays a pivotal role in managing emergency trip scenarios.
The module features 12 relays arranged in two rows of six, which facilitate the interface with the primary protection system and accommodate inputs from flame detectors.
In Triple Modular Redundant (TMR) applications, the module employs relay ladder logic in two out of three voting circuits to enhance redundancy and reliability.
