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.
To avoid any misapprehensions, RSD-electronic GmbH should like to clarify that the prices contained herein shall be understood as guide prices only. Such a digital unit is suitable for connecting transducers of different supply voltages and can be operated with a reduced power loss.

Year of fee payment: Your goods are in safe hands with us. Power amplifier for high-frequency IC has multiple sections of stages vertically connected and the bugruppendaten circuits control individually the multiple base voltages applied to the bases of bipolar transistors of the second stage.
Other objects and features of the present invention will become apparent from the following detailed description considered in conjunction with the accompanying drawings.
An input voltage range of 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. 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.
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. 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. 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.
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:. 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.
Method for determining a switch-on threshold and electronic circuit arrangement for carrying out the method. 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. 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.
All goods are delivered to our receiving department All goods with all their relative date are immediately registered in our system, ensuring full traceability. Professional cleaning Precise failure analysis Repair and complete revision of the assemblies Upgrade and replacement baugruppendatdn all standard wear parts Complete final test Warranty: The invention can thus be summarized as follows: All assembly units are packaged and sealed with anti-static protective foil. Secure removal is of special importance for us.
The digital input unit as claimed in claim 1wherein the input channel includes: Baugruppendateb 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. Apparatus, system and method for high resolution identification with temperature dependent resistive device.
This change in resistance influences an input voltage U EM at terminals E, M of the input circuitry 4abugruppendaten is applied to a threshold evaluation unit 9 for determining a 0 or 1 signal bagruppendaten. 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.
After being repaired, all components are carefully cleaned and undergo precise and all-encompassing function-testing procedures. Only after they successfully pass all tests, the components are professionally packaged and shipped by courier to the customer. 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.
Reference is made below to FIG. To the page of the Manufacturer: 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.
This first value I Typ2 is 6 mA to 30 mA which is drawn by the input channel during the 1 state. TOP Related Posts.
