The constantly increasing demand for automation
technology means that ever larger amounts of data have
to be processed.
A highly diverse range of interface converters in serial and
digital form are used in such instances.
They are primarily used to adapt different data protocols
and for converting analogue signals
into digital ones or vice versa.
