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 also configured to limit the input current I to a first value I Typ2 up to a baugrupendaten 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 Sthe input channel has a resistive behavior and is also configured to limit the input current I to a first value I Typ2 below U Sthe 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.

This first baugruppehdaten I Typ2 is 6 mA to 30 mA which is drawn by the input channel during the 1 state.

To the page of the Manufacturer: Reference is made below to FIG. In a second operating mode in which the input voltage 30 EM exceeds the changeover voltage U S formed by the resistors R 3R 4the transistor V turns on and the current I is determined by the diodes V 1V 2 and the resistor R 1. Specially designed internal and external protective packaging provides optimal transport protection. Circuit arrangement for voltage selection, and method for operating a circuit arrangement for voltage selection.

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.

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.

This and other objects and advantages are achieved by virtue of the fact that an input channel of the digital input unit is configured to limit the input current to a first value up to a changeover voltage, where the changeover voltage is greater than or equal to a voltage limit 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.

In this case, the digital input unit must be designed for a multiplicity of DC input voltages, for example in a range from 24 V to V. The input circuitry 4 comprises a current sink 5 and switching device 6 which switch the current sink 5 to a first operating baugruppendaten and z7 second operating mode based on the input voltage at baufruppendaten E, M of the input circuitry 4.

This second value I Typ1 is selected such that this value is in the range of 2 mA to 15 mA at the input voltage representing the 1 state according to the type 1 characteristic curve. It should be further understood that the drawings are not necessarily drawn to scale and that, unless otherwise indicated, they are merely intended to conceptually illustrate the structures and procedures described herein. 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.

The invention can thus be summarized as follows: Year of fee payment: EP EPA1 en 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. All goods are delivered to our receiving department All goods with all their relative date are immediately registered in our system, ensuring full traceability. Such a digital unit is suitable for connecting transducers of different supply voltages and can be operated with a reduced power loss.

Up to an input voltage limit of 30 V, which represents the upper limit of the V nominal range, the digital input unit has a type 2 behavior according to the IEC or EN standard.

According to the type 1 characteristic, the upper current limit for a 0 or 1 signal state is 15 mA, but is 30 mA according to the type 2 characteristic. RSD-electronics GmbH makes these documents available but assumes no liability and offers no guarantee in respect of their correctness. 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 baugrkppendaten 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.

Only after they successfully pass all tests, the components baugruppendateen professionally packaged and shipped by courier to the customer.

Thus, while there have shown, described and pointed out fundamental novel features of the invention as applied to a preferred embodiment thereof, it will be understood that various omissions and substitutions and changes in the form and details of the devices illustrated, and in their operation, may be made by those skilled in the art without departing from the spirit of the invention.

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.

In this case, the current I is set to the second value I Typ1 which is lower than the first value I Typ2. One embodiment of the invention provides simple circuitry measures which are used to set the constant current to the first or second value.

It is therefore an object of the invention to provide a digital input unit which is suitable for connecting transducers of different supply voltages and which is operable with a reduced power loss.

The digital input unit as claimed in claim 1wherein the input channel includes: Download start up and backup procedures, error messages, manuals and more here.

This standard prescribes current and voltage limits for 0 and 1 signal states for the type 1 and type 2 characteristics, the current limits according to the type baugruppendzten characteristic being higher than those predefined according to the type 1 characteristic.

It is the intention, therefore, to be limited only as indicated by the baugruppndaten of the claims appended hereto. After being repaired, all components are carefully cleaned and undergo precise and all-encompassing function-testing procedures. 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.

All assembly units are packaged and sealed with anti-static protective foil. The invention, its refinements and advantages are explained in more detail below using the drawing which illustrates an exemplary embodiment of the invention and 30 which:.

Professional cleaning Precise failure analysis Repair and complete revision of the assemblies Upgrade and replacement of all standard wear parts Complete final test Warranty: An input voltage range of 5 V to 11 V defines baugtuppendaten transition region which describes neither a 0 nor a 1 state, where the input channel is able to baugruppeneaten a current of 2 mA to 30 mA in this transition region.
