Abstract: An electro-hydraulic control device is equipped with a valve and with activating electronics for the electrical activation of the valve as a function of a control signal. A sensor component or actuator component which is held on the valve, is connected to the activating electronics by means of an electrical connecting line. A non-volatile data memory is arranged on or in the sensor component or the actuator component, and the data of the data memory can be read out via the electrical connecting line.

Abstract: An electrical voltage arrangement to be provided with selectively 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 arrangenent 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.

Abstract: An electrical circuit arrangement for converting an input voltage into an impressed electrical output variable, to convert the input voltage optionally into an output voltage or into an output current, wherein the input voltage is fed to the desired value input of a regulator. A negative feedback voltage is fed to the actual value input of the regulator, the voltage being a measure of the respectively effective output variable. For converting the input voltage into an impressed output voltage, the negative feedback voltage is a voltage proportional to the output voltage. For converting the input voltage into an impressed current, the negative feedback voltage is a voltage dropped across a resistor through which the output current flows. Circuit arrangements of this type serve for further processing of a unipolar voltage in circuit arrangements which require a current as input variable, or a voltage whose range deviates from that of the input voltage. This is the case e.g.

Abstract: In a device for controlling a hydraulic actuator having an electrically actuated valve which controls the flow of pressure medium to and from the actuator, a controller for the position of the valve piston is integrated in the housing of the valve or arranged on the latter in a housing of its own. In order additionally to integrate axial functionality into a device of this type, a second controller, provided for controlling the pressure or the quantity of the pressure medium fed to the actuator, is arranged in the same housing as the controller for the position of the valve piston. Devices of this type are used for example in machine tools.
