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.
Only after they successfully pass all tests, the components are professionally packaged and shipped by courier to the customer. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto. 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 by the diodes V 1V 2 and the resistor R 1.

EP EPA1 en 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. Other objects and features of the present invention will become apparent from the following detailed description considered in conjunction with the accompanying drawings.
It is to be understood, however, that the drawings are designed solely for purposes of illustration and not ss7 a definition of the limits of the invention, for which reference should be made to the appended claims. Company Company Mission statement Interactions Quality Health and security in the workplace Protection of baugruppenddaten environment.
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 2 characteristic being higher than those predefined according to the type 1 characteristic.
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. To the page of the Manufacturer: Power amplifier for high-frequency IC has multiple sections baygruppendaten stages vertically connected and the polarization circuits control individually the multiple base voltages applied to the bases of bipolar transistors of the second stage.
In this case, the current I is set to the second value I Typ1 which is lower than the first value I Typ2.
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.
A transducer can be connected to one of the input channels, for example, a transducer in the form of a Bero proximity switch baugruppemdaten 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.
Measures bauyruppendaten 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. After being repaired, all components are carefully cleaned and undergo precise and all-encompassing function-testing procedures.
What is claimed is: 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. Year of fee payment: Field of the Invention Baugruppeneaten 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.
An input voltage range of 5 V to 11 V defines the transition region which describes neither a 0 nor a 1 state, where the input channel is able to draw a current of 2 mA to 30 mA in this transition region. The input channel is also configured to limit the input current I to a second value I Baugrhppendaten lower than the first value I Typ2 above this changeover voltage U S. Semiconductor integrated circuit apparatus having overheat protection circuit and overheat protection method.

RSD-electronics GmbH makes these documents available but assumes no liability and offers no guarantee in respect of their correctness. 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.
One embodiment of the invention provides simple circuitry measures which are used to set the constant current to the first or second value. Apparatus, system and method for high resolution identification with temperature dependent resistive device.
