SY3700 Triple Redundancy Over-speed Protection System
SY3700-G is a triple redundant overspeed protection system, which can be applied to critical scenarios such as steam turbines, compressors, and motors that have functional safety SIL3 level requirements. The equipment consists of three redundant-configured speed monitoring modules, SY3701-G. Each speed monitoring module adopts a dual-core processor architecture, enabling low latency, high precision, and high reliability for overspeed protection functions.
