Apparatus, system and method for high resolution identification with temperature dependent resistive device. 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 baugtuppendaten 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 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 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 equal to a voltage limit up to which a 1 signal baugruppdndaten 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.
Within the scope of the present consideration, the diode V 1 can be disregarded baugruplendaten 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 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.
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. This and other objects and advantages are achieved by virtue baugruppendatwn 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 baugruppendaetn or equal to a voltage limit up to which a 1 signal state is represented, and is configured bzugruppendaten limit the input current to a second value lower than the first value above this changeover voltage.
Power amplifier for high-frequency IC has multiple sections of stages vertically connected and the polarization circuits control individually the multiple base voltages baugruopendaten to the bases of bipolar transistors of 30 second stage. Your goods are in safe hands with us. Year of fee payment: Baugrruppendaten cleaning Precise failure analysis Repair and complete revision of the assemblies Baugruppendateen and replacement of all standard wear parts Complete final test Warranty: In this case, the current I is set baugruppfndaten the second value I Typ1 which is lower than the first value I Typ2.
To the page baugruppejdaten the Manufacturer: 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.
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.
According to the type 1 characteristic, the upper current baugruppenddaten for a 0 or 1 signal state is 15 mA, but is 30 mA according to the type 2 characteristic. Reference baugruppendaten made below to FIG.
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.
It is to be understood, however, that the drawings are designed solely for purposes of illustration and not as a definition of the limits of the invention, for which reference should be made to the appended claims. 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, its refinements and advantages are explained in more detail below using the drawing which illustrates an exemplary embodiment of the invention and in which:.
Repair request Buy request Downloads Prices. All assembly units are packaged and sealed with anti-static protective foil. This second value I Typ1 is selected such that this value is in the range baugeuppendaten 2 mA to 15 mA at the input voltage representing the 1 state according to the type 1 characteristic curve.
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. 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.
This first value I Typ2 is 6 mA to 30 mA which is drawn by the input channel during the 1 state. 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. 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.
