Abstract

The relay has at least one working contact (3), conductive on a control signal at the relay input terminals (1, 1'), and at least one rest contact (7). The voltage, applied to the working contact so controls the rest contact that, with the working contact blocked, its voltage makes the rest contact. With the working contact made and possibly still with low rest voltage, the rest contacts remains open. Pref. The input circuit (1, 1'), the working contact circuit (5, 5'), and the rest contact circuit (8, 8') are mutually galvanically separated.

Im Prinzip arbeiten elektronische Relais, wie in Fig. 1 schematisch darge­ stellt, mit einem Arbeitskontakt 3, über den, bei vorhandenem Steuersignal an den Eingangsklemmen 1 und 1', der zu schaltende Strom 4 fließt, und bei fehlendem Steuersignal dieser Stromfluß unterbrochen wird.In principle, electronic relays, as shown in Fig. 1 schematically Darge, with a normally open contact 3 , via which, with a control signal present at the input terminals 1 and 1 ', the current to be switched 4 flows, and if there is no control signal, this current flow is interrupted.

In der Regel enthält der Eingangskreis eine oder mehrere lichtemittierende Dioden 2 eines Optokopplers. Der Arbeitskontakt 3 wird durch Schaltun­ gen mit Transistoren, Thyristoren und/oder Triacs realisiert, die durch die lichtemittierende Diode 2 leitend gemacht oder gesperrt werden.As a rule, the input circuit contains one or more light-emitting diodes 2 of an optocoupler. The normally open contact 3 is realized by circuits with transistors, thyristors and / or triacs, which are made conductive or blocked by the light-emitting diode 2 .

Die an den Anschlußklemmen 5 und 5, liegende geschaltete Spannung kann Gleich- oder Wechselspannung sein. Bei Bedarf kann man mehrere elektronische Relais zusammenschalten, um mehrere Arbeitskontakte zu haben.The switched voltage at the connection terminals 5 and 5 can be direct or alternating voltage. If necessary, several electronic relays can be interconnected in order to have several working contacts.

Die Aufgabe besteht darin, ein elektronisches Relais zu schaffen, das sowohl einen Arbeitskontakt als auch einen von diesem vorzugsweise gal­ vanisch getrennten Ruhekontakt aufweist und das zum Schalten sowohl von Gleich- als auch von Wechselstrom geeignet ist. The task is to create an electronic relay that both a work contact and one of these preferably gal Vanically separated normally closed contact and that for switching both of direct as well as alternating current is suitable.  

Diese Aufgabe wird durch die in Anspruch 1 gekennzeichnete Erfindung gelöst. Die Erfindung bietet die Möglichkeiten,
This object is achieved by the invention characterized in claim 1. The invention offers the possibilities

  • - daß der Arbeits- und/oder der Ruhekontakt Schaltungen mit Dioden, Transistoren, Thyristoren, Triacs, integrierten Schaltungen, logischen Schal­ tungen, Schmitt-Triggern, Fotozellen, Fotowiderständen enthält, und- That the working and / or the normally closed circuits with diodes, Transistors, thyristors, triacs, integrated circuits, logic scarf contains, Schmitt triggers, photocells, photo resistors, and
  • - daß das Schalten der Relaiskontakte immer im Nulldurchgang einer Wechselspannung geschieht, und- That the switching of the relay contacts always at zero crossing AC voltage happens, and
  • - daß zwischen Arbeits- und Ruhekontakt ein Zeitverzögerungsglied geschaltet ist, wodurch das Schalten des Ruhekontakts erst nach einer gewünschten Zeit erfolgt, und- That a time delay between work and rest contact is switched, whereby the switching of the normally closed contact only after one desired time, and
  • - daß an Stelle nur eines Ruhe- und/oder eines Arbeitskontakts mehrere Kontakte realisiert werden.- That instead of just one rest and / or work contact several Contacts can be realized.

Ein Vorteil dabei ist, daß man durch die entsprechende Wahl des Arbeits- und Ruhekontakts ein elektronisches Wechselspannungsrelais erhalten kann.One advantage is that you can choose the right work and Get an electronic AC voltage relay can.

Im folgenden wird die Erfindung unter Bezugnahme auf die Zeichnung näher erläutert. Es zeigen:In the following the invention with reference to the drawing explained in more detail. Show it:

Fig. 1 ein Schaltbild eines bekannten elektronischen Relais, Fig. 1 is a circuit diagram of a known electronic relay,

Fig. 2 ein Schaltbild einer bevorzugten Ausführungsform der Erfindung und Fig. 2 is a circuit diagram of a preferred embodiment of the invention and

Fig. 3 ein Anwendungsbeispiel des elektronischen Relais gemäß Fig. 2. Fig. 3 shows an application example of the electronic relay of FIG. 2.

Die erfindungsgemäße Schaltung eines elektronischen Relais mit einem zusätzlichen Ruhekontakt ist in Fig. 2 schematisch dargestellt. Diese Schal­ tung enthält neben dem ersten elektronischen Relais I noch ein zweites elektronisches Relais II, das nur dann den Strom 9 leitet, wenn die Kon­ taktspannung an dem Schaltelement 3 des elektronischen Relais I liegt, also wenn der Arbeitskontakt 3 gesperrt ist, und die Kontaktspannung über das Anpassungsnetzwerk 10 an den Eingangsklemmen 11 und 11' des elektronischen Relais II liegt. Dadurch wird sichergestellt, daß der Ruhe­ kontakt 7 erst nach dem Öffnen des Arbeitskontakts 3 geschlossen wird. The circuit according to the invention of an electronic relay with an additional normally closed contact is shown schematically in FIG. 2. This scarf device contains, in addition to the first electronic relay I, a second electronic relay II, which only conducts the current 9 when the contact voltage at the switching element 3 of the electronic relay I, that is when the normally open contact 3 is blocked, and the contact voltage via the matching network 10 at the input terminals 11 and 11 'of the electronic relay II. This ensures that the normally closed contact 7 is only closed after opening the working contact 3 .

Verbindet man zum Beispiel die Klemmen 5 und 8 (Fig. 2), so kann man die Schaltung aus Fig. 2 vereinfacht wie in Fig. 3 darstellen, wobei der durch den Arbeitskontakt 3 zu speisende Verbraucher 12 und der durch den Ruhekontakt 7 zu speisende Verbraucher 13 an der Quelle 14 der elektri­ schen Energie liegen.If, for example, terminals 5 and 8 are connected ( FIG. 2), the circuit from FIG. 2 can be represented in a simplified manner as in FIG. 3, the consumer 12 to be fed by the normally open contact 3 and the consumer 12 to be fed by the normally closed contact 7 Consumers 13 are at the source 14 of the electrical energy.

Durch die Erfindung wird also ein elektronisches Relais geschaffen, bei dem zum Schalten des Ruhekontaktes die am Arbeitskontakt liegende Spannung benutzt wird, wobei der Eingangskreis des Relais und die beiden Kontakt­ kreise untereinander galvanisch getrennt sein können.The invention thus creates an electronic relay in which the voltage at the normally open contact to switch the normally closed contact is used, the input circuit of the relay and the two contacts circles can be galvanically isolated from each other.
