Description

The invention relates to automation and may find application in relay counters of pulse signals.

The aim of the invention is to simplify by eliminating the capacitor and diode in each cell.

The drawing shows a structurally electrical circuit of the distributor.

The distributor contains a contact ed control group 1, a capacitor 2, an outdoor installation button 3, and in each cell there is a double-wound polarized relay 4 with NC 5 and NO 6 contacts, a zener diode ed 7 and a thyristor 8.

The relay distributor operates as follows.

After supplying the supply voltage with the button 3 of the initial installation, the distributor 2Q divider is returned to the initial state, in which all two-winding polarized relays 4 are switched off. In this case, the capacitor 2 is charged to voltage. power supply through a current-limiting resistor .. When the state of contact group 1 of the control changes, the thyristor 8 of the first cell is turned on and the capacitor 2 is discharged to include the winding of a double-winding polarized relay 30 of the first cell. The relay 4 of the first cell is turned on, opening the opening contact 5 of the first cell and closing the making contact 6 of the second cell, thereby providing a thyristor 8 circuit of the second cell. When the state of the contact group 1 control when it returns to its original state, shown in the drawing, the capacitor 2 is recharged.

When the state of the contact group 1 of the control is changed a second time, which corresponds to the second command, the thyristor 8 of the second cell is turned on, ensuring that relay 4 of the second cell is turned on.

In the future, the dispenser operation is exhausted after the relay of the last cell is triggered, it is returned to its initial state by button 3 of the initial installation.

The stabilization voltage of the zener diodes is selected less than the voltage of the power source, but more than the voltage that remains on the capacitor after the next switching on of the relay (after closing the make contact).
