Triple redundant overspeed protection device (SY3700)
TMR overspeed protection device（SY3700）
SY3700 is a triple overspeed protection system that can be applied to critical occasions with SIL3 level requirements, such as steam turbines, compressors, motors, etc. The device includes three redundant speed monitoring modules SY3701, each of which adopts a dual 32-bit RISC processor architecture to achieve low latency, high precision, and high reliability overspeed protection function. Currently widely used in high-speed, non mechanical overspeed trip units, large units, etc.
