Description

The invention relates to a pulse technique and can be used in various devices of discrete automation.

, 1.3.1., 1.2.1 - windings of the relay 1 common bus 4. The switching contact of the contact group 1.1.1 is thrown and prepares the switch-on circuit of the relay 1.2 from the pulse at the input 11.

When the switch 8 is pressed by a current pulse passing through ’capacitor 9, the thyristor turns on

2.1, which includes the relay 1.2, the latter becomes self-blocking due to the contact group

1.2.1, while the relay 1.1 is turned off. The switching contact of the contact group 1.2.1 is thrown and prepares the switching circuit of the relay .1.3, etc. (it should be borne in mind that the time constant of the charge circuit of the capacitor 9 should be less than the time of switching on the relay 1). When the switch contact switch 8 returns to its original position

the capacitor 9 is discharged through the current limiting resistor 10.

When η-m press the switch 8 current pulse passing through the 5th capacitor 9, the thyristor turns on

2.p, through which the charge of the capacitor 6 is provided to the turn-on voltage of the dynistor 7. When the voltage on the capacitor 6 is reached at 10 turn-on of the dynistor 7, the last

turns on, switching the winding of the relay 1. (And + 1) to the capacitor 6. Relay 1. (n + 1) turns on, the contacts of group 1. (n + 1) .1 opens, relay 1.p turns off. When a voltage drops on the capacitor 6, which is lower than the holding voltage of the relay 1. (c + 1), the relay 1. (n + 1) turns off, the contacts of group 1. (n + 1) .1 close and the relay 1.1 operates, preparing the switch-on circuit of the relay 1.2, i.e. providing counter operation to recycle.
