An electrical voltage arrangement is to be provided with which different electrical input variables, for example in the form of a unidirectional voltage, a bidirectional voltage or a unidirectional current, can be converted into an impressed electrical output voltage. At the same time, there is to be a predefined relationship between the input variable and the output voltage. The circuit arrangement contains a first arithmetic circuit which converts a voltage fed to it into a first impressed voltage, and a second arithmetic circuit which converts an input voltage fed to it into a second impressed voltage. The voltage which is present at the input terminals of the circuit arrangement is fed to the first arithmetic circuit. The voltage which drops across a resistor which can be connected to the input terminals of the circuit arrangement is fed to the second arithmetic circuit. If the input variable which is to be converted is a voltage, the output voltage of the first arithmetic circuit is used as an output voltage of the circuit arrangement. If the input variable which is to be converted is a current, the current is fed to the resistor, and the output voltage of the second arithmetic circuit is used as the output voltage of the circuit arrangement. The circuit arrangement is provided for use in automation equipment.
