PLC-Based Emergency Trip System (ETS-LM)
About ETS-LM
ETS-LM is developed based on the HollySys LM-G3 PLC platform, which completes core functions such as data acquisition, calculation, and output. It is suitable for small turbine units. Using PLC system as the main controller has the advantages of fast response, high reliability, long life, centralized management, decentralized control, easy logic modification, convenient increase or decrease of protection conditions, etc.
