Abstract

An assembly with a secondary coil arranged on a coil carrier for a field device is described, wherein the field device comprises an electronics and an inductive interface connected to the electronics, and wherein the assembly can be used in the field device such that the field device can be connected via its interface to an inductive interface of a superordinate unit such that the secondary coil of the assembly, with a primary coil of the inductive interface of the superordinate unit, form a transformer for transmitting data and/or energy, which makes it possible to reduce the dimensions of field devices equipped with it and also contributes to increased operational safety, in that an assembly circuit formed by the secondary coil and at least one electronic component connected to the secondary coil via lines connected to it and arranged on the coil carrier is arranged on the coil carrier.
