Von Elektronikkreisen gesteuertes RelaisRelay controlled by electronic circuits
Die Erfindung bezieht sich auf ein von Elektronikkreisen gesteuertes Relais mit einem Abschaltüberspannungsschutz und einer parallel zur Relaisspule liegenden Reihenschaltung aus Widerstand und Leuchtdiode.The invention relates to one of electronic circuits Controlled relay with a switch-off overvoltage protection and a parallel to the relay coil Series connection of resistor and light emitting diode.
Bei einem bekannten Relais der obengenannten Art ist als Abschaltüberspannungsschutz parallel zur Relaisspule und der Reihenschaltung aus Widerstand und Leuchtdiode zusätzlich ein spannungsabhängiger Widerstand (Varistor) eingeschaltet, was einen relativ hohen Aufwand für diesen Schutz bedeutet. Der Erfindung liegt die Aufgabe zugrunde, ein Relais der obengenannten Art zu schaffen, bei dem der Abschaltüberspannungsschutz mit weniger aufwendigen Mitteln erreicht werden kann. Dies wird auf einfache Weise dadurch erreicht, daß der Abschaltüberspannungsschutz aus einer der Leuchtdiode zugeschalteten Diodenschaltung besteht. Eine einfache Ausführung der Diodenschaltung ergibt sich, wenn der Leuchtdiode eine Diode antiparallel geschaltet ist. Wird die Leuchtdiode in einer Brückend!agonale einer Gleichrichterbrückenschaltung eingeschaltet, so ergibt sich zusätzlich der Vorteil, daß die Relaisansteuerung polungsunabhängig ist.In a known relay of the type mentioned above, the switch-off overvoltage protection is parallel to the relay coil and the series connection of resistor and light-emitting diode also has a voltage-dependent resistor (Varistor) switched on, which means a relatively high effort for this protection. The invention lies the object of the invention is to create a relay of the type mentioned above, in which the switch-off overvoltage protection can be achieved with less expensive means. This is achieved in a simple manner in that the Switch-off overvoltage protection consists of a diode circuit connected to the light-emitting diode. A simple one The diode circuit is implemented when the light-emitting diode is connected in anti-parallel with a diode. If the light-emitting diode is in a bridging! Agonal one Rectifier bridge circuit switched on, then there is the additional advantage that the relay control is polarity independent.
Anhand der Zeichnung werden Ausführungsbeispiele gemäß der Erfindung beschrieben.Exemplary embodiments according to the invention are described with reference to the drawing.

Fig. 2 die Leuchtdiode in einer Brückendiagonale an einer Gleichrichterbrückenschaltung eingeschaltet.2 the light-emitting diode switched on in a bridge diagonal on a rectifier bridge circuit.
Bei der Ausführungsform nach Fig. 1 ist die Spule des Relais 1 einerseits mit den Anschlüssen 2, 3 und andererseits mit dem einen Ende des Widerstandes 4 am AnschluS 3 und andererseits mit den einen Enden der Leuchtdiode 5 und der Diode 6 am Anschluß 2 verbunden. Der Verbindungspunkt des anderen Endes des Widerstandes 4 mit den anderen Enden der Leuchtdiode 5 und der Diode 6 ist mit 7 bezeichnet. Anstelle der Diode 6 ist im Ausführungsbeispiel nach Fig. 2 ein Brückengleichrichter 8 angeordnet, dessen eine Diagonale vom Verbindungspunkt mit dem Anschluß 2 gebildet wird; in der anderen Diagonale liegt die Leuchtdiode 5. Diese Schaltungsanordnung hat den Vorteil, daß zum überspannungsschutz die dreifache Diodenspannung ausgenutzt werden kann,und darüber hinaus kann die Polarität der Steuerspannung beliebig gewählt werden, da die Leuchtdiode durch den Brückengleichrichter stets in Durchlaßrichtung mit Strom beaufschlagt wird. Die mit der erfindungsgemäßen Schaltungsanordnung erreichbaren Abschaltspannungen liegen in der gleichen Größenordnung wie die Abschaltüberspannungen, die mit einem Varistor erreicht werden können, jedoch liegen die hierzu aufgewendeten Kosten bei der Ausführungsform nach Fig. 1 etwa bei 20 % und bei der Ausführungsform nach Fig. 2 bei ca. 70 %. In the embodiment according to FIG. 1, the coil of the relay 1 is connected on the one hand to the terminals 2, 3 and on the other hand to one end of the resistor 4 at the terminal 3 and on the other hand to the one ends of the light-emitting diode 5 and the diode 6 at the terminal 2. The connection point of the other end of the resistor 4 with the other ends of the light-emitting diode 5 and the diode 6 is denoted by 7. Instead of the diode 6, a bridge rectifier 8 is arranged in the embodiment according to FIG. 2, one diagonal of which is formed by the connection point with the connection 2; on the other diagonal is the light-emitting diode 5. This circuit arrangement has the advantage that three times the diode voltage can be used for overvoltage protection, and the polarity of the control voltage can be chosen as desired, since the light-emitting diode is always supplied with current in the forward direction by the bridge rectifier . The switch-off voltages that can be achieved with the circuit arrangement according to the invention are of the same order of magnitude as the switch-off overvoltages that can be achieved with a varistor, but the costs incurred for this are around 20 % in the embodiment according to FIG. 1 and around 20% in the embodiment according to FIG. 2 approx. 70 %.
