Abstract

In the distributed control and information system (DCIS) for the electric power plant, the input and output modules occupy a large proportion of the components. Therefore, in order to reduce the cost and size of the total system, it is important to reduce those of the input and output modules. In this paper, the application of the multiple output DC-DC power converter to the photo-coupler analog signal isolator is introduced instead of using the conventional electromagnetic isolation
