Description
Den Transistor Tl und das Relais 9 kann man als Spannungsteiler auffasssen. Liegt kurzzeitig eine Eingangsspannung U0 an, wird der Transistor Tl leitend und nachfolgend auch der Transistor Tl. Dadurch wird das Spannungsgefälle am Spannungsteiler aus dem jetzt niederohmigen Transistor Tl und dem Relais 9 mit der Schutzdiode 10 zu positiveren Werten verschoben. Da die Rückkopplung am Punkt 20, dem Mittelabgriff des Spannungsteilers, angeschlossen ist, gelangt jetzt über die Rückkopplungsleitung 17, die Rückstelltaste 4, den Widerstand 2, die Diode 1 und den Widerstand 16 eine Spannung auf die Basis des Transistors Tl, die ausreicht, ihn leitend zu halten. Wird die Rückkopplungsleitung 17 mit der Rückstelltaste 4 unterbrochen, so werden die Transistoren Tl und Tl wieder nichtleitend, sofern kein Eingangssignal Ue ansteht.The transistor T1 and the relay 9 can be viewed as a voltage divider. If an input voltage U 0 is applied briefly, the transistor Tl becomes conductive and subsequently also the transistor Tl. This shifts the voltage gradient at the voltage divider from the now low-resistance transistor Tl and the relay 9 with the protective diode 10 to more positive values. Since the feedback is connected to point 20, the center tap of the voltage divider, a voltage that is sufficient for it now reaches the base of the transistor T1 via the feedback line 17, the reset button 4, the resistor 2, the diode 1 and the resistor 16 to keep conductive. If the feedback line 17 is interrupted with the reset button 4, the transistors Tl and Tl become non-conductive again, provided there is no input signal U e .
Der Widerstand 12 geht von der Minusleitung 19 auf die Basis des Transistors T3. Von der Basis des Transistors Γ 3 führt ein Widerstand 11 zum Kollektor des Transistors Tl. Der Emitter des Transistors T 3 ist direkt mit der Minusleitung 19 verbunden.The resistor 12 goes from the negative line 19 to the base of the transistor T3. A resistor 11 leads from the base of the transistor Γ 3 to the collector of the transistor Tl. The emitter of the transistor T 3 is connected directly to the negative line 19.
In seinem Kollektorkreis liegt ein Widerstand 15. der mit der Plusleitung 18 verbunden ist. Der Transistor 74 liegt mit seiner Basis am Kollektor des Transistors T3 und mit seinem Emitter an der Minusleitung 19. Der Kollektor des Transistors T4 ist mit dem Punkt 21 verbunden.A resistor 15, which is connected to the positive line 18, is located in its collector circuit. The base of the transistor 74 is connected to the collector of the transistor T3 and its emitter is connected to the negative line 19. The collector of the transistor T4 is connected to the point 21.
Die Widerstände 11 und 12 bilden mit dem Transistor T2 einen Spannungsteiler, der so bemessen ist, daß der Transistor Γ3 leitet, wenn eine Eingangsspannung Ue anliegt und somit die Transistoren Π und Tl leiten. Der Transistor TA ist in diesem Fall wegen des niederohmigen Transistors Γ 3 gesperrt, der mit dem Widerstand 15 den Eingangsspannungsteiler für den Transistor Γ 4 bildet.The resistors 11 and 12 form a voltage divider with the transistor T2 , which is dimensioned so that the transistor Γ3 conducts when an input voltage U e is applied and thus the transistors Π and Tl conduct. The transistor TA is blocked in this case because of the low-resistance transistor Γ 3, which forms the input voltage divider for the transistor Γ 4 with the resistor 15.
Die mit der Erfindung erzielten Vorteile bestehen darin, daß eine bekannte Schaltung mit geringem
Mehraufwand an Bauelementen zu einer gegen Störimpulse gesicherten Schaltung erweitert wurde.
Die Ausführung der Schaltung ist ohne NachteileThe advantages achieved by the invention are that a known circuit has been expanded to a circuit protected against interference pulses with little additional expenditure on components.
The design of the circuit has no disadvantages
so auch in integrierter Schaltungstechnik möglich.so also possible in integrated circuit technology.
In diesem Fall wird für die Kippstufe ein Schaltverstärker verwendet.In this case, a switching amplifier is used for the multivibrator.
