Abstract
A control device includes an electrically contactless depluggable logic module such as a computer that is used to interface between a power supply and input and output elements to process a system of control signals. There are no electrical connections to the logic module. This eliminates electromagnetic interference and conducted line interference. The power supply is magnetically coupled to the logic module. Information and control signals are optically coupled to the logic module. It is a free standing, environmentally immune unit, electrically isolated from the outside world.
