Abstract

In its use this circuit operates at relay speeds to enter high speed pulses into electronic solid state counters for preset count or limit purposes and is particularly adaptable to automatic control systems. These pulses can also be entered manually with this circuit.

Preset Pulse Circuit

In its use this circuit operates at relay speeds to enter high speed pulses into electronic solid state counters for preset count or limit purposes and is particularly adaptable to automatic control systems. These pulses can also be entered manually with this circuit.

A read in pulse fires the transistor, which may be of either the NPN or PNP type, and places a collector voltage on the particular capacitor selected by either relay or keying means. The value of the capacitor determines how many pulses are generated after the read in pulse disappears and are created by oscillation of the L-C tank circuit. The output can be fed to a level set circuit, if needed for greater reliability due to the nature of the damped oscillations.
