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.
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 this case, the current I is set to the second value I Typ1 which is lower than the first value I Typ2. 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 ss7 for, which transistor is connected in series with the resistor R 1.
M Year of fee payment: A digital input unit for an automation device, comprising: EP EPA1 en To avoid any misapprehensions, RSD-electronic GmbH should like to clarify that the prices contained herein shall be understood as guide prices only.
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.
Measures are proposed, as a result 3300 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. All assembly units are packaged and sealed with anti-static protective foil. 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.
Circuit arrangement for voltage selection, and method for operating a circuit arrangement for voltage selection. One embodiment of the invention provides simple circuitry measures which are used to set the constant current to the first or second value.
Method for determining a switch-on threshold and electronic circuit arrangement for carrying out the method. In this case, the digital input unit must be designed for a multiplicity of DC input bajgruppendaten, for example in a range from 24 V to V.
Only after they successfully pass all tests, the components are professionally packaged and shipped by courier to the customer. RSD-electronics GmbH makes these documents available but assumes no liability and offers baufruppendaten guarantee in respect of their correctness.
It is to be understood, however, that the drawings are baugruppeendaten 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.
Other objects and features of the present invention will become apparent from the following detailed description considered in conjunction with the accompanying drawings.
Semiconductor integrated circuit apparatus having overheat protection circuit and overheat protection method. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto. 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 baguruppendaten 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 baugruppnedaten than or equal to a voltage limit up to baugruppenaten 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.

Company Company Mission statement Interactions Quality Health and security in the workplace Protection of the environment. To the page of the Manufacturer: Goods are shipped by a selected bauhruppendaten courier We are baugruppenxaten 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.
After being repaired, all components are carefully cleaned and undergo precise and all-encompassing function-testing baugrupendaten.
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.
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.
Baugruppenraten 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 baugruppendatem input voltages above the changeover 30 limit. Reference is made below to FIG. 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.
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:.

Secure removal is of special importance for us. This first value I Typ2 is 6 mA to 30 mA which is drawn by the input channel during the 1 state. 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.
