Siemens EM11T I/O Module

Feature & Principle

It is a dedicated high-speed I/O card for Siemens SIMADYN D control system. It collects analog process signals, digital switching signals and SSI absolute encoder signals, and transmits them to the main processor via rack backplane bus. It also outputs analog control signals and digital switching signals to actuators. It features fast sampling cycle to meet the dynamic regulation requirements of turbines and generators, widely used for power generation set speed, excitation and load closed-loop control.
