Bei der Signalisierung werden als Meldungen von fehlerhaften Geräten Fehlersignale und als Meldungen über die Nichtverfügbarkeit von Nachrichtenverbindungen Störungssignale erzeugt. Diese führen zu einem dringenden Alarm (A-Alarm) oder zu einem nicht dringenden Alarm (B-Alarm), die in Signalfeldern angezeigt werden. Quittierte Signale werden durch eine Erinnerungslampe kenntlich gemacht. Meldungen aus Signalfeldern werden an Sammelleitungen von Gestellreihen weitergegeben.During the signaling, error signals are generated as messages from faulty devices and fault signals as messages about the unavailability of message connections. These lead to an urgent alarm (A alarm) or a non-urgent alarm (B alarm), which are displayed in signal fields. Acknowledged lamps are identified by a reminder lamp. Messages from signal fields are passed on to manifolds of rack rows.

Bekannt sind Signalfelder, die mit einer Betriebsspannung von -12V und solche, die mit einer Betriebsspannung von -24V arbeiten.Signal fields are known which operate with an operating voltage of -12V and those which operate with an operating voltage of -24V.

Aufgabe der Erfindung ist es, eine Anordnung zur Anregung von Relais, insbesondere für ein Signalfeld anzugeben, die mit zwei verschiedenen Betriebsspannungen arbeitet. Ein Signalfeld mit der erfindungsgemäßen Anordnung soll beispielsweise die beiden bekannten Signalfelder ersetzen können.The object of the invention is to provide an arrangement for exciting relays, in particular for a signal field, which works with two different operating voltages. A signal field with the arrangement according to the invention should, for example, be able to replace the two known signal fields.

Ausgehend von einer Anordnung zur Anregung von Relais wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß in einer ersten, an einer Betriebsspannung angeschlossenen Reihenschal tung ein Relais, eine Parallelschaltung aus einem ersten widerstand und aus einem ersten Schalter sowie ein zweiter Schalter angeordnet sind, daß ein an die Betriebsspannung angeschlossener Komparator vorgesehen ist, der bei Anliegen eines oberen Werts der Betriebsspanmmg eine logische Null und bei Anliegen eines unteren Werts eine logische Eins abgibt, daß eine monostabile Kippstufe vorgesehen ist, an deren Eingang ein Anregungssignal anlegbar ist, daß ein erstes ODER-Gatter vorgeschen ist, dessen erster Eingang mit dem Ausgang des Komparators, dessen zweiter Eingang mit dem Ausgang der monostabilen Kippstufe und dessen Ausgang über eine erste Schalteransteuerung mit einem Steuereingang des ersten Schalters verbunden sind, daß ein zweites ODER-Gatter vorgesehen ist, dessen erster Eingang mit dem Ausgang und dessen zweiter Eingang mit dem Eingang der monostabilen Kippstufe und dessen Ausgang über eine zweite Schalteransteuerung mit einem Steuereingang des zweiten Schalters verbunden sind und daß der Wert des ersten Widerstandes so bemessen ist, daß die Haltespanmmg des Relais nicht unterschritten wird.Based on an arrangement for exciting relays, this object is achieved in that In a first, connected to an operating voltage series circuit device, a relay, a parallel circuit consisting of a first resistor and a first switch and a second switch are arranged that a comparator connected to the operating voltage is provided, the one when an upper value of the operating voltage is applied logic zero and if a lower value is present a logic one indicates that a monostable multivibrator is provided, at the input of which an excitation signal can be applied, that a first OR gate has occurred, the first input of which is connected to the output of the comparator, the second input of which is the output of the monostable multivibrator and its output are connected via a first switch control to a control input of the first switch, that a second OR gate is provided, the first input of which is connected to the output and the second input of which is connected to the input of the monostable multivibrator and its output via a second switch ran control are connected to a control input of the second switch and that the value of the first resistor is dimensioned such that the holding voltage of the relay is not undercut.

Für die Funktion der Anordnung ist es vorteilhaft, wenn der erste Schalter bei dem oberen Wert der Betriebsspannung aufgrund einer logischen Null am Ausgang des Komparators offen ist und nur bei Auftreten der logischen Eins am Ausgang der monostabilen Kippstufe geschlossen ist, wenn der erste Schalter bei einem unteren Wert der Betriebsspannung aufgrund der logischen Eins am Ausgang des Komparators geschlossen ist und wenn der zweite Schalter bei Auftreten der logischen Eins am Eingang oder Ausgang der monostabilen Kippstufe geschlossen ist.For the function of the arrangement, it is advantageous if the first switch at the upper value of the operating voltage is open due to a logic zero at the output of the comparator and is only closed when logic one occurs at the output of the monostable multivibrator, if the first switch is at a lower value of the operating voltage is closed due to the logic one at the output of the comparator and if the second switch is closed when logic one occurs at the input or output of the monostable multivibrator.

Eine Anordnung zur individuellen Anregung mehrerer Relais ist dadurch gekennzeichnet, daß zwischen dem ersten Schalter und dem Relais eine Entkopplungsdiode vorgesehen ist, daß n weitere Relais vorgesehen sind, daß n weitere erste Reihenschaltungen ohne ersten Schalter aber mit Entkopplungsdiode vorgesehen sind, daß eine Verbindung der relaisabgewandten Anschlüsse der Entkopplungsdiode vorgesehen ist, daß n weitere monostabile Kippstufen mit Eingängen vorgesehen sind, daß ein erstes ODER-Gatter mit n weiteren Eingängen vorgesehen ist, an die jeweils ein Ausgang der weiteren n monostabilen Kippstufen angeschlossen sind, daß n weitere zweite ODER-Gatter vorgesehen sind, deren Eingänge mit einem Ein- und einem Ausgang der zugeordneten monostabilen Kippstufe und deren Ausgänge über jeweils eine von n weiteren zweiten Schalteransteuerungen mit den Steuereingängen der zugeordneten weiteren n zweiten Schalter verbunden sind.An arrangement for the individual excitation of several relays is characterized in that between the first Switch and the relay a decoupling diode is provided, that n further relays are provided, n further first series connections are provided without a first switch but with decoupling diode, that a connection of the relay-facing connections of the decoupling diode is provided, that n further monostable multivibrator stages are provided with inputs that a first OR gate is provided with n further inputs, to each of which an output of the further n monostable multivibrators is connected, that n further second OR gates are provided, the inputs of which have one input and one output of the assigned monostable multivibrator and whose outputs are each connected to the control inputs of the assigned further n second switches via one of n further second switch controls.

Eine vorteilhafte Ausgestaltung der Erfindung besteht darin, daß die Schalter durch Transistoren realisiert sind.An advantageous embodiment of the invention is that the switches are implemented by transistors.

Ein vorteilhaftes Detail der Erfindung besteht darin, daß der Komparator aus einer zweiten, an der Betriebsspannung angeschlossenen Reihenschaltung aus einer Zenerdiode und aus einem zweiten Widerstand und aus einem an den Mittelabgriff dieser zweiten Reihenschaltung angeschlossenen Inverter besteht, dessen Ausgang als Komparatorausgang dient.An advantageous detail of the invention is that the comparator consists of a second series circuit connected to the operating voltage, a zener diode and a second resistor and an inverter connected to the center tap of this second series circuit, the output of which serves as a comparator output.

Ein vorteilhafter Einsatz der erfindungsgemäßen Anordnung erfolgt bei Betriebsgleichspannungen in Bereichen von -12V und -24V bzw. -24V und -60V.An advantageous use of the arrangement according to the invention takes place at operating DC voltages in the range of -12V and -24V or -24V and -60V.

Anhand von Ausführungsbeispielen wird die Erfindung nachstehend erläutert.The invention is explained below using exemplary embodiments.

  • Fig. 1 zeigt eine erfindungsgemäße Anordnung mit einem Relais.Fig. 1 shows an arrangement according to the invention with a relay.
  • Fig. 2 zeigt eine erfindungsgemäße Anordnung mit drei Relais.Fig. 2 shows an arrangement according to the invention with three relays.

  • Fig. 4 zeigt detailliert eine Anordnung nach den Figuren 2 und 3.4 shows an arrangement according to FIGS. 2 and 3 in detail.
  • Figur 1 zeigt eine erfindungsgemäße Anordnung. Diese enthält ein Relais 1, einen Widerstand 2, Schalter 3 und 5, einen Komparator 6, eine monostabile Kippstufe 7, einen Eingang 8, ODER-Gatter 9 und 11, sowie Schalteransteuerungen 10 und 12. Der Kontaktsatz des Relais 1 ist als nicht zur Erfindung gehörig nicht dargestellt.Figure 1 shows an arrangement according to the invention. This contains a relay 1, a resistor 2, switches 3 and 5, a comparator 6, a monostable multivibrator 7, an input 8, OR gates 9 and 11, and switch controls 10 and 12. The contact set of relay 1 is not for Invention not properly shown.

Bei Relais liegt die Haltespannung zum Teil wesentlich niedriger als die Ansprechspannung. Daher genügt es, wenn das Relais bis zum Ansprechen an eine Spannung gelegt wird, die größer als die minimale Ansprechspannung ist. Danach kann die Spannung auf den Wert der Haltespannung abgesenkt werden. Das Relais 1 hat eine Nennspannung, die dem unteren Wert der Betriebsspannung UB entspricht.In the case of relays, the holding voltage is sometimes significantly lower than the response voltage. It is therefore sufficient if the relay is connected to a voltage that is greater than the minimum response voltage until it responds. The voltage can then be reduced to the value of the holding voltage. Relay 1 has a nominal voltage which corresponds to the lower value of the operating voltage U B.

Der Schalter 3 wird bei dem unteren Wert der Betriebsspannung UB vom Komparator 6 über das ODER-Gatter 9 und die Schalteransteuerung 10 geschlossen und legt das Relais 1 direkt an die Betriebsspannung UB. Der Zustand am anderen Eingang des ODBR-Gatters 9 ist jetzt wirkungslos.The switch 3 is closed at the lower value of the operating voltage U B by the comparator 6 via the OR gate 9 and the switch control 10 and applies the relay 1 directly to the operating voltage U B. The state at the other input of the ODBR gate 9 is now ineffective.

Bei einem oberen Wert der Betriebsspannung UB kann der Schalter 3 nur vom Ausgangssignal der monostabilen Kippstufe 7 für deren Impulsdauer über das ODER-Gatter 9 und die Schalteransteuerung 10 geschlossen werden. Diese Impulsdauer ist derart bemessen, daß das Relais 1 sicher anspricht. Nach dieser Zeit liegt das Relais über den Wiederstand 2 an der Betriebsspannung UB. Dieser ist so dimensioniert, daß die minimale Haltespannung nicht unterschritten wird.At an upper value of the operating voltage U B , the switch 3 can only from the output signal of the monostable Flip-flop 7 are closed for their pulse duration via the OR gate 9 and the switch control 10. This pulse duration is dimensioned such that the relay 1 responds safely. After this time, the relay is connected to the operating voltage U B via resistor 2. This is dimensioned so that the minimum holding voltage is not undercut.

Die Ansteuerung des Relais 1 erfolgt über den Schalter 5. Während der Kippzeit der monostabilen Kippstufe 7 wird der Schalter 5 über das ODER-Gatter 11 und die Schalteransteuerung 12 geschlossen, auch wenn der Anregungsimpuls am Eingang 8 kürzer ist. Bei Anregungsimpulsen, die länger als die Kippzeit andauern, erfolgt die Schließung des Schalters 5 unter Umgehung der monostabilen Kippstufe 7.The control of relay 1 takes place via switch 5. During the tilting time of monostable multivibrator 7, switch 5 is closed via OR gate 11 and switch control 12, even if the excitation pulse at input 8 is shorter. In the case of excitation pulses that last longer than the tilting time, the switch 5 is closed by bypassing the monostable multivibrator 7.

Figur 2 zeigt eine erfindungsgemäße Anordnung für drei Relais 1, 1', 1". Die verwendeten Bezugszeichen entsprechen denen in Figur 1. Die dem Relais 1' zugeordneten Elemente tragen ein Bezugszeichen mit ebenfalls einem Apostroph, die dem Relais 1" zugeordneten Elemente tragen Bezugszeichen mit zwei Apostrophen. Eine Sonderstellung nimmt das ODER-Gatter 9' ein, da in ihm drei einzelne ODER-Gatter vereint sind. Zusätzlich sind Entkopplungsdioden 4, 4' und 4" eingeführt.FIG. 2 shows an arrangement according to the invention for three relays 1, 1 ', 1 ". The reference symbols used correspond to those in FIG. 1. The elements assigned to relay 1' have a reference symbol with an apostrophe as well, the elements assigned to relay 1" have reference symbols with two apostrophes. The OR gate 9 'has a special position, since it combines three individual OR gates. In addition, decoupling diodes 4, 4 'and 4 "are introduced.

Bei einem oberen Wert der Betriebsspannung UB wird der Schalter 3 nur dann geschlossen, wenn am Ausgang wenigstens einer der monostabilen Kippstufe 7, 7', 7" eine logische Eins anliegt. Da nur ein Schalter 3 vorhanden ist, werden alle Relais 1, 1', 1" beim Ansprechen eines Relais über den Schalter 3 und die Entkopplungsdioden 4, 4', 4" an die Betriebsspannung UB gelegt. Bereits angesprochene Relais werden dadurch nochmals kurzzeitig an die Betriebsspannung UB gelegt. Dies hat keinen Einfluß auf die Funktion der bereits angesprochenen Relais. Der Rest der Anordnung arbeitet wie bei der nach Figur 1.If the operating voltage U B is at an upper value, the switch 3 is only closed if at least one of the monostable multivibrators 7, 7 ', 7 "is present at the output. Since only one switch 3 is present, all relays 1, 1 ', 1 "when a relay responds via the switch 3 and the decoupling diodes 4, 4', 4" to the operating voltage U B. Relays that have already been addressed are thus briefly connected to the operating voltage U B again. This has no influence on the function of the relays already mentioned. The rest of the arrangement works like that of FIG. 1.

Figur 3 zeigt einen Komparator 6, der aus einer Zenerdiode 13, einem Widerstand 14 und einem CMOS-Inverter 15 besteht.FIG. 3 shows a comparator 6, which consists of a zener diode 13, a resistor 14 and a CMOS inverter 15.

Der Inverter 15 wird an einer Hilfsbetriebsspannung U'B von 10V betrieben. Die typische Schaltschwelle liegt somit bei 5V. Ist die Betriebsspannung UB kleiner als die Summe von Spannung der Zenerdiode 13 und Ansprechschwelle des Inverters 15, so ist dessen Ausgang auf logisch Eins. Wird die Betriebsspannung UB größer als diese Summe, so nimmt der Ausgang des Inverters 15 den logischen Pegel Null an.The inverter 15 is operated at an auxiliary operating voltage U ' B of 10V. The typical switching threshold is 5V. If the operating voltage U B is less than the sum of the voltage of the Zener diode 13 and the response threshold of the inverter 15, its output is at logic one. If the operating voltage U B is greater than this sum, the output of the inverter 15 assumes the logic level zero.

Figur 4 zeigt die Anordnung nach Figur 2 detaillierter. Die Anordnung enthält einen Komparator 6 nach Figur 3, bei dem der Inverter 15 durch ein NOR-Gatter 15' mit seinem erstes Eingang realisiert ist.Figure 4 shows the arrangement of Figure 2 in more detail. The arrangement contains a comparator 6 according to FIG. 3, in which the inverter 15 is implemented by a NOR gate 15 'with its first input.

Das ODER-Gatter 9' besteht aus Dioden 16, 17, 18 und aus dem NOR-Gatter 15' im Hinblick auf seinen zweiten Eingang an der Verbindungsleitung 19.The OR gate 9 'consists of diodes 16, 17, 18 and the NOR gate 15' with regard to its second input on the connecting line 19.

Der Schalter 3 und seine Schalteransteuerung 10 bestehen aus Widerständen 20 bis 23 und Transistoren 24 und 25. Die Schalter 5, 5', 5" mit ihren Schalteransteuerungen 12, 12', 12" sind durch Transistoren 29 bis 31 und Widerstände 32 bis 34 realisiert.The switch 3 and its switch control 10 consist of resistors 20 to 23 and transistors 24 and 25. The switches 5, 5 ', 5 "with their switch controls 12, 12', 12" are implemented by transistors 29 to 31 and resistors 32 to 34 .

Es ist ein oberer Wert der Betriebsspannung UB im Bereich von -20V bis -26,4V und ein unterer Wert im Bereich von -10,5V bis -13,5V zulässig.An upper value of the operating voltage U B in the range from -20V to -26.4V and a lower value in the range from -10.5V to -13.5V is permissible.

Die Spannung der Zenerdiode 13 ist mit 13V derart gewählt, daß der entsprechende Eingang des NOR-Gatters 15' im Bereich des unteren Wertes unterhalb der Schaltschwelle liegt. Der Ausgang des NOR-Gatters 15' ist damit in diesem Bereich auf Minuspotential, was ein Durchschalten der Transistoren 24 und 25 über die Diode 16 bewirkt. Der zweite Eingang des NOR-Gatters 15' ist dadurch wirkungslos. Damit werden die Relais 1, 1', 1" über die Dioden 4, 4', 4" an die Betriebsspannung UB gelegt.The voltage of the Zener diode 13 is chosen to be 13V such that the corresponding input of the NOR gate 15 'is in the range of the lower value below the switching threshold. The output of the NOR gate 15 'is thus in this region at minus potential, which causes the transistors 24 and 25 to be switched through via the diode 16. The second input of the NOR gate 15 'is therefore ineffective. Relays 1, 1 ', 1 "are thus connected to operating voltage U B via diodes 4, 4', 4".

Bei dem oberen Wert der Betriebsspannung UB wird der eine Eingang des NOR-Gatters 15' über den Widerstand 35 soweit negativ, daß, falls der andere Eingang ebenfalls negativ ist, der Ausgang mit Sicherheit Massepotential annimmt. Die Transistoren 24 und 25 sind gesperrt. Das NOR-Gatter 15' wird jetzt nur noch von den Ausgängen der monostabilen Kippstufen 7, 7', 7" gesteuert.At the upper value of the operating voltage U B , one input of the NOR gate 15 'via the resistor 35 becomes negative to such an extent that, if the other input is also negative, the output assumes ground potential with certainty. Transistors 24 and 25 are blocked. The NOR gate 15 'is now only controlled by the outputs of the monostable multivibrators 7, 7', 7 ".

Die Dioden 26 bis 28 sind Löschdioden.The diodes 26 to 28 are quenching diodes.
