Description

Der Transistor 12 wird aber nur dann durchgesteuert, wenn an dem Hilfswiderstand M eine Spannung ausreichender Größe und geeigneter Richtung abfallt.

The relay 13 can only with Put on leavened transistor 12. The transistor 12 is only activated when the voltage across the auxiliary resistor M is sufficient Size and appropriate direction drops. The drawn in Spunnungsquelk · 15 is intended to be indicated be that the circuit must be potential-free in the present arrangement.

Diese Schwierigkeit läßt sich bei einer Anordnung nach Fig. 3 vermeiden. Diese Schaltung enthält einen bistabilen Kipper 16, der aus zwei Transistoren 17 und 18 besteht. Das Relais 13 zieht erst dann an, wenn der erste Transistor 17 gesperrt und der Transistor 18 somit durchlässig ist. Der Transistor 17 wird gesperrt, wenn eine ausreichend hohe positive Spannung vom Gruppensteiler her an -,einem Eingang anliegt. Durch Anlegen einer veränderlichen negativen Vorspannung kann dem Sperren dieses Transistors entgegengewirkt werden, so daß lieh ein. Umkippen der Schaltung auf die jeweils gewünschteThis difficulty can be avoided with an arrangement according to FIG. This circuit includes a bistable tipper 16, which consists of two transistors 17 and 18. The relay 13 only picks up, when the first transistor 17 is blocked and the transistor 18 is thus conductive. The transistor 17 is blocked when there is a sufficiently high positive voltage from the group divider to -, an input is applied. By applying a variable negative bias voltage, this can be locked Transistor are counteracted, so that borrowed a. Flip the circuit to the desired one

positive Spannung einstellen läßt. Werden die Widerstände des bistabilen Kippers 16 entsprechend dimensioniert, so nimmt der Kippverstärker ein sogenanntes Schwellwertverhalten an, wobei der Schwellwert beliebig einstellbar ist. Die Hystereseschleifepositive voltage can be set. If the resistances of the bistable tipper 16 are dimensioned accordingly, so the trigger amplifier assumes a so-called threshold value behavior, the threshold value can be set at will. The hysteresis loop
