The GE IS200TRPGH1B Turbine Protection & Relay Processing Gateway (TRPG) Module is a critical discrete I/O and protection interface board engineered for GE Mark VI turbine control systems. This module acts as a central relay processing gateway that bridges protection logic outputs and field relay actuation, ensuring that trip commands, alarms, and protective responses are reliably delivered to external devices such as circuit breakers, contactors, annunciators, and other critical actuators.
Designed to excel in demanding industrial environments, the IS200TRPGH1B provides enhanced signal conditioning, isolation, and output integrity to meet the strict availability and safety requirements of power generation systems. Its well-structured relay output handling supports complex protection and control logic within Mark VI architectures.
