The invention relates to automation and can be used, for example, in relay counters of pulse signals.

The purpose of the invention is to improve the reliability and efficiency of the distributor by eliminating the capacitor with the corresponding circuits in each of the units.

The drawing shows a schematic diagram of the inventive distributor, which contains n parallel connected cells, each of them contains three conclusions, while the third conclusions of the odd cells are combined and connected to the cathode of the common diode 8, and the third conclusions of the even cells are connected to the cathode of the diode 9. Each of the cells has a single-wound polarized relay 12, opening contact 10 of this relay, making contact 11 of the relay

previous cell, except the first, as well as

diode 13. Common elements are, in addition to the above diodes 8, 9, a capacitor 3, a control contact group 2 and 4, an initial installation button 1 with opening and closing contacts, a charging resistor 5, diodes 14, 15, 16 , 17, a first power supply terminal 6, a second power supply terminal 7.

The operation of the device. After the supply voltage is supplied by the button 1, the distributor is returned to its initial state. There is a charge of the capacitor 3 along the circuit: the first terminal 6 of the power source - the NC contact of the button 1 of the initial installation of the distributor - the NC contact of the first control contact group 2 - diode 14 - capacitor 3 - diode 17 - the NC contact of the first control contact group 4 - resistor 5 is a second terminal 7 of a power source. When the state of the control contact group 2 and 4 changes, the capacitor 3 is discharged along the circuit: capacitor plate 3 - diode 8 - third output of the first cell

- NC opening contact of this cell - relay coil 12 - first output of this cell

- the opening contact of the button 1 of the initial installation - the closing contact of the first control contact group 2 - diode 15 - the lining of the capacitor 3. Relay 12 of the first cell is activated and with its making contact 11 prepares the switching circuit of the relay of the second cell, Capacitor 3 continues to recharge on the circuit : the first terminal 6 of the power source is the opening contact of the initial installation button 1 - the closing contact of the first control contact group 2 - diode 15 - capacitor 3 - diode 16 - the closing contact of the second control contact group 14 5

resistor 5 - second terminal 7 of the power source.

When the state of the control contact group 2 and 4 changes, which corresponds to the second command, the capacitor 3 is discharged along the circuit: capacitor plate 3 - diode 9 - third output of the second cell

- making contact 11 of the relay of the first cell - opening contact 10 of the relay of the second cell - winding of relay 12 of the second cell - first output of this cell - opening contact of button 1 of the initial installation - opening contact of the first control contact group 2 - diode 14 - capacitor plate 3. Relay 12 of the second cell is activated and prepares the circuit to turn on the relay of the third cell, and the capacitor 3 is recharged, etc., with each new state of the control group of contacts 2 and 4. After the last cell is activated, the distributor capacity is exhausted.

When the button 1 is pressed, its NC contact opens the charge circuit of the capacitor 3, and the NO contact switches on the circuit of the second terminals of all cells and the current passes through the circuit: the first terminal 6 of the power supply

- first terminals of all cells - relay windings 12 - diodes 13 - second terminals of all cells - closing contact of button 1 of the initial installation - second terminal 7 of the power source. As a result, the relay distributor returns to its original state.

Thus, the introduction of an additional group of control contacts allows us to abandon the capacitor in each of the n-cells, and to use one common capacitor with the corresponding group of semiconductor diodes, which improves the reliability of operation and reduces the cost of the distributor. This determines the technical and economic effect of its use.
