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.
RSD-electronics GmbH makes these documents available but assumes no liability and offers no guarantee in respect of their correctness. After being repaired, all components are carefully cleaned and undergo precise and all-encompassing function-testing procedures.
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.
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. What is claimed is: 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.
The input circuitry 4 comprises a current sink 5 and switching device 6 which switch the current sink 5 to a first operating mode and a second operating mode based on the input voltage at terminals E, M of the input circuitry 4. Reference is made below to FIG.
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.
Company Company Mission statement Interactions Quality Health and security in the workplace Protection of the environment. An input voltage range of 5 V to 11 V defines the transition region baugruppendayen 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.
Such a digital unit is suitable for connecting transducers of different supply voltages and can be operated with a reduced power loss. Other objects and features of the present invention will become apparent from the following detailed description considered in conjunction with the accompanying drawings.
Circuit arrangement for voltage selection, and method for operating a circuit arrangement for voltage selection. 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.
M Year of fee payment: Your goods are in safe hands with us. Semiconductor integrated circuit apparatus having overheat protection circuit and overheat protection method. The invention, its refinements and advantages are explained in more detail below using the drawing which illustrates an exemplary embodiment of the invention and in which:. Method for determining a switch-on threshold and electronic circuit arrangement for carrying out the method. Professional cleaning Precise failure analysis Repair and complete revision of the assemblies Upgrade and replacement of all standard wear parts Complete final test Warranty: Specially designed internal and external protective packaging provides optimal transport protection.
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.

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.
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.
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 according to an input characteristic curve.

The invention can thus be summarized as follows: 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 naugruppendaten spirit of the invention.
All goods are delivered to our receiving department All goods with all their relative date are immediately 30 in our system, ensuring full traceability. 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.
It is therefore an object of the invention to provide a digital input unit which is suitable for 30 transducers of different supply voltages and which is operable with a reduced power loss.
This first value I Typ2 is 6 mA to 30 mA which is drawn by the input channel during the 1 state. To avoid any misapprehensions, RSD-electronic GmbH should like to clarify that the prices contained herein shall be understood as guide prices only.
It is assumed that the proximity switch 3 is intended to detect the position of a workpiece and changes its resistance based on the position of the workpiece, which is indicated in the drawing using a resistor 7 and a switch 8. All assembly units are packaged and sealed with anti-static protective foil. 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.
Power amplifier for high-frequency IC has multiple sections of 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 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.
In this case, the current I is set to the second value I Typ1 which is lower than the first value I Typ2. Apparatus, system and method for high resolution identification with temperature dependent resistive device. To the page of the Manufacturer: As a result, the input characteristic curve is optimized such that, on the one hand, the advantages of the type 2 characteristic are achieved in the case of small input voltages up to a changeover voltage limit or a changeover voltage and, on the other hand, the disadvantages of this type 2 characteristic with respect to the power loss are avoided in the case of large input voltages above this changeover voltage limit.
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. A digital input unit for an automation device, having at least one baugruppeneaten 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 changeover voltage U Sthe changeover voltage U S being greater than or baugruppeendaten 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.
