In a second operating mode in which the input voltage U EM exceeds the changeover voltage U S formed by the resistors R 3R 4the transistor V turns on and the current I is determined baugruppehdaten the diodes V bagruppendatenV 2 and the resistor R 1. In order to enable a fast and transparent budget calculation, RSD-electronic GmbH specifies a price range including special packaging for the desired products or services. The situation may then occur in which, on account of a customer requirement, a digital input unit must perform functions for a multiplicity of transducers of different nominal DC voltages.

A digital input unit for an automation device includes at least one current drawing DC input channel for connecting a transducer operated at a nominal DC voltage, where the input channel is configured to set the current based on an input voltage UEM baugrjppendaten to an input characteristic curve.

In this case, in order to avoid this disadvantage, the input current is reduced to the input current according to the type 1 characteristic in the case of large input voltages above the changeover voltage limit. It should be further understood that the drawings are not necessarily drawn to scale and that, unless otherwise indicated, they are baugtuppendaten intended to conceptually illustrate the structures and procedures described herein. Field of the Invention The invention relates to a digital input unit for an automation device having at least one current-drawing DC input channel for connecting a transducer operated at a nominal DC voltage, where the input channel is configured to set the current based on the input voltage according to an input characteristic curve.

A digital input unit for an automation device, having at least one current I -drawing DC input channel for connecting a transducer 3 operated at a nominal DC voltage, the input channel being configured to set the current I based on the input voltage U EM according to an input characteristic curve, is distinguished by the fact that the input channel is baugrruppendaten configured to limit the input current I to a first value I Typ2 up to a changeover voltage U Sthe changeover voltage U S being greater than or equal to a voltage limit up to which a 1 signal state is represented, and to limit the input current I to a second value I Typ1 lower than the first value I Typ2 above this changeover voltage U S.

At low input voltages U up to a voltage U Baugrjppendatenthe input channel has a resistive behavior and is also configured to limit the input current I to a first value I Typ2 below U S baugruppenvaten, the changeover voltage U S being greater than or equal to the voltage limit of 30 V, up to which the 1 signal state is represented. It is to be understood, however, that the drawings are designed solely for purposes of illustration and not as a baugruppednaten of the limits of the invention, for which reference should be made to the appended claims.

To the page of the Manufacturer: The input channel is also configured to limit the input current I to a second value I Typ1 lower than the first value I Typ2 above this changeover voltage U S.

All assembly units baugruppdndaten packaged and sealed with anti-static protective foil. M Year of fee payment: Only after they successfully pass all tests, the components are professionally packaged and shipped by courier to the customer.

A transducer can be connected to one of the input channels, for example, a transducer in the form of a Bero proximity switch which is designed for a nominal DC voltage of 24 or 48 V, an input characteristic curve complying with a so-called type 1 or type 2 characteristic according to the IEC or EN standard.

Circuit arrangement for voltage selection, and method for operating a circuit arrangement for voltage selection.

Measures are proposed, as a result of which the digital input unit is suitable for connecting transducers of different supply voltages, where the digital input unit is operable with a reduced power loss. This change in resistance influences an input voltage U EM at terminals E, M of the input circuitry 4which is applied to a threshold evaluation unit 9 for determining a 0 or 1 signal state.

In accordance with the invention, the input characteristic curve is set, which represents the dependence of the current on the input voltage, based on the input voltage.

Secure removal is of special importance for us. Download start up and backup procedures, error messages, manuals and more here. According to the type 1 characteristic, the upper current limit for a 0 or x7 signal state is 15 mA, but is 30 mA according to the type 2 characteristic.

This and other objects and advantages are achieved by baugruppensaten of the fact that an input channel of the digital input unit is configured to limit the input current to a first baugruppenfaten up to a changeover voltage, where the changeover voltage is greater than or equal to a voltage z7 up to which a 1 signal state is represented, and is configured to limit the input current to a second value lower than the first value above this changeover voltage.

The digital input unit as claimed in claim 1wherein the input channel includes: Within the scope of the present consideration, the diode V 1 can be disregarded because the voltage drop and the voltage drop across the base-emitter diode of a transistor V are compensated for, which transistor is connected in series with the resistor R 1.

The invention can thus be summarized as follows: Such a digital unit is suitable for connecting transducers of different supply voltages and can be operated with a reduced power loss.
