Analog / digital - signal transducer means with galvanic separation into the mixed signal transmission path via

摘要

Analog / digital - signal transducer means (2, 15) for high information content, by way of 1 bit of an input-side analog voltage signal (v_in), whereina) the input side (e) by an insulation barrier (3) is galvanically separated from an output side (a) is,b) on the input side (e) means to a conversion of the input-side analog voltage signal (v_in) in, an input-side analog current signal (s_in) are provided, which means for the conversion of the input-side analog current signal (s_in) in an analog magnetic field signal (h) with a clearly from the signal strength of the analog current signal are arranged downstream of the magnetic field strength which is dependent on,andc) on the output side (a) a the magnetic field signal (h), a sensor (7, 18) to a unique, from the characteristic curve of the sensor is dependent on conversion of the magnet field signal (h) into an analog sequence signal (s_out) is provided, wherein the sensor (7, 18) includes means for converting the sequential signal (s_out) in a digital output-side voltage signal (v_out) are associated with.
