EPRO A6371/00 Overspeed Protection Backplane

Overview

The EPRO A6371/00 backplane is a critical component in Emerson's AMS 6300 SIS Overspeed Protection System. It ensures the safe operation of turbines by preventing overspeed conditions, which can lead to catastrophic failures. The backplane integrates with A6370 overspeed protection monitors and employs redundant trip logic for reliable and safe turbine shutdown. Its compact design fits into a 19” rack, offering efficient system integration while maintaining high reliability and safety compliance.
