Abstract

Disclosed is a field device electronics for a field device of automation engineering, comprising: first and second terminals for connecting the field device electronics to a cable for an electrical input current to the field device electronics; a series regulator to set the input current; a shunt regulator following the series regulator; a first capacitance connected in parallel with the shunt regulator for energy storage; a supply circuit connected in parallel with the shunt regulator and the first capacitance for providing an operating voltage; and connected after the supply circuit and supplied by the operating voltage, a control unit adapted to register a buffer voltage lying across the first capacitance, based on the registered buffer voltage, to make a decision concerning at least one part of the field device electronics.
