Abstract

The invention relates to an electronic system for a field device that comprises a power controller, through which a supply current flows, for setting and/or modulating the supply current, the latter being driven by a supply voltage that is provided by means of the external energy supply. The electronic system for a field device also comprises an internal operating and evaluation circuit for controlling the field device, in addition to an internal supply circuit that is applied to an internal input voltage of the field device electronic system, is separate from the supply voltage and feeds the internal operating and evaluation circuit. A voltage controller, through which a first partial current of the supply current flows at least intermittently, is provided in the supply circuit, said controller providing an essentially constantly controlled first internal useful voltage at a predeterminable voltage level in the electronic system of the field device. In addition, the supply circuit comprises a second voltage controller, through which a second partial current of the supply current flows at least intermittently, said controller providing a second internal useful voltage in the electronic system of the field device that can be varied within a predeterminable voltage range and a voltage controller, through which a third partial current of the supply current flows at least intermittently, for setting and maintaining the internal input voltage of the field device electronic system at a predeterminable voltage level. According to the invention, both a first useful current that is driven by the first useful voltage and a second useful current that is driven by the second useful voltage flow through the operating and evaluation circuit.
