Abstract (en)
Multifunction time control device composed of a first programmed circuit (1) with programs selected by microswitches (6); of a second oscillator circuit (2) generating a fixed frequency of 32.768 Hz afterwards divided by a couple of counters in order to obtain a 1 Hz frequency and by further counters to furtherly divide said frequency and obtain signals with 1 minute and 1 hour pulses; of a third circuit (3) equipped with trigger and logic comparators to select time scales, of a fourth circuit (4) equipped with a programmable counter selected by preselectors (8) and of a supply circuit (5) generating different voltage values. <IMAGE>
