E80 General turbomachinery safety protection device（ETS）
E80 uses highly-reliable all-hardware loops to protect turbomachinery from failures and downtime without the need for programming. It has 20 independent protection channels, where 10 channels are 2 out of 3 switch inputs, and 10 channels are single switch inputs. Every channel has an independent hard switch. Safe-level products are used for relays that send out downtime messages, and the basic protection part uses a triple redundancy framework that is suitable for the safety protection devices of different types of turbomachinery.
