Abstract

Eine Ankoppelschaltung für einen Busteilnehmer (101) an eine Busleitung (102) eines Feldbusses mit gleichspannungsfreier und differentieller, EIA-485/EIA-422 konformer Signalübertragung nach einem TTP-Protokolll, bei welcher die beiden Eingänge/Ausgänge (108, 109) einer Sende/Empfangs­komponente (104) des Busteilnehmers (101) mit einer ersten Wicklung eines Signalübertragers (103) und die beiden Pole der Busleitung (102) mit einer zweiten Wicklung des Signalübertragers verbunden sind und die erste Wicklung eine Mittenanzapfung (107) aufweist, wobei die Mittenanzapfung (107) mit dem lokalen Bezugspotential des Busteilnehmers (101) über einen Kondensator (105) verbunden ist, dessen Kapazität mindestens das 100-fache der parasitären Kapazität (110) des Übertragers (103) beträgt.
