Abstract
The present invention relates in general to the field of interface technology. Electronic components, such as modular converters for measurement control and regulation technology, in particular isolation amplifiers, are known from interface technology. Such isolation amplifiers can be used for galvanic separation, conversion, amplification and filtering of standard, normal signals and for matching analog signals. These isolation amplifiers are galvanically separated from one another in the input, output and supply circuits. According to the invention, a separate component of a transformer is integrated for separation into a circuit board of an isolation amplifier with the aid of SMD mounting technology, wherein the transformer contains a combination of inductive components, consisting of a magnetic core and a winding, and a substrate which contains internal printed conductors that form planar short-circuit windings.
