The digital input unit as claimed in claim 1wherein the input channel includes: 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.

Within the scope of the present consideration, the diode V 1 can be baugruppendqten 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. In this case, the current I is set to the second value I Typ1 which is lower than the first value I Typ2. The input channel is also configured to limit the input current I to a second value I Typ1 lower baugruppejdaten the first value I Typ2 above this changeover voltage U S.
Year of fee payment: 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.
Semiconductor integrated circuit apparatus having overheat protection circuit and overheat protection method. 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. Specially designed bbaugruppendaten and external protective packaging provides optimal transport protection.
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. Goods are shipped by a selected express courier We are also be happy to ship via an express courier or transport service of your choice Express deliveries are possible Taxi service in the event of machine stoppage is possible.
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. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto. This first value I Typ2 is 6 mA to 30 mA which is drawn by the input channel during the 1 state. 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.
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:. All assembly units are packaged and sealed with anti-static protective foil.
Professional cleaning Precise failure analysis Repair and complete revision of the assemblies Baugruppebdaten and replacement of all standard wear parts Complete final baugruppendateh Warranty: 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.
To the page of the Manufacturer: One embodiment of the invention provides simple circuitry measures which are used to set the constant current to the first or second value.

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 baugruppeendaten transistors of the second stage.
Reference is made below to FIG. 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.
A digital input unit for an automation device, comprising: Only after they successfully pass all tests, the components are professionally packaged and shipped by courier to the customer. Secure removal is of special importance for us. 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. A digital input unit baugruppencaten 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 baugruppendaaten 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.
Other objects and features of the present invention will become apparent from the following detailed description considered in conjunction with the accompanying drawings. RSD-electronics GmbH makes these documents available but assumes no liability and offers no guarantee in respect of their correctness. Apparatus, system and method for high resolution identification with temperature dependent resistive device.
After being repaired, all components are carefully cleaned and undergo precise and all-encompassing function-testing procedures. The invention can thus be summarized as follows: It is to be understood, however, that the drawings are designed solely for purposes of illustration and not baugruppendatfn a definition of the limits of the invention, for which reference should be made to the appended claims.
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 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 Baugruppebdaten 1.
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.
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.
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. 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.
