製品紹介
The GE IS220PPRAH1A Emergency Turbine Backup Protection I/O Module is a critical component in GE’s Mark VIe control system architecture, designed to provide high-integrity, independent protection for industrial and power generation turbines.
This module acts as a secondary backup to the primary turbine controller, providing fast and reliable emergency shutdown capability for gas and steam turbines in the event / a critical fault or controller failure. The IS220PPRAH1A module is specifically engineered to interface directly with the turbine trip mechanisms, emergency shutdown devices (ESD), and overspeed protection systems.
It operates independently / the primary control system logic, with hardwired inputs and outputs for maximum integrity and response time. Featuring robust diagnostics, isolated I/O, and compliance with rigorous industry safety standards, the IS220PPRAH1A ensures an added layer / protection to safeguard critical equipment and personnel.
