A disadvantage of the known distribution of bodies is the most frequent triggering of the clock generator relay: four times when it is required to receive two pulses in a series, six 3 times in three pulses in a series, etc., i.e. according to the number of front and rear edges of pulses in a series. Other turnips for the period of the series follow work only one by one. In this case, it must be taken into account that: the load of the switching contact of the relay of the generator is inductive, the ST (preparatory windings). All this reduces the reliability of the device. The purpose of the invention is to increase the reliability of the relay distributor. The goal is achieved by the fact that a switchboard containing a clock generator and a generator of a series of periods with corresponding relays, a switch made to the relay, whose blocking windings are connected to generator inputs via moving contacts of a clock generator and h a cut - with a power source, and other outputs of the blocking windings are connected via a disconnecting contact of the generator of the period following the series to the common bus and the leads of the preparatory windings barely switch wherein the other terminals of windings odd preparatory relay ra commutators are connected through the closing Comte you previous even commutators ra relay, and even relay switch - through zamykayu1schy previous odd relay contact switch.

FIG. 1 shows the functionality of the distributor circuit; in fig. 2 (a, b, c, d, d, e) are time diagrams of the proceeding processes. The distributor contains a clock generator 1 and a generator 2 of period 4 following the series with the corresponding relays 3 and 4, a series switch, performed on the double-winding relay 5-8, a switch 9 of the power supply, and also the first and second transistor switches 10 and P The leads of winding windings of two-winding relays 5-8 through their closing contacts 12-15 are connected to the input of the generators I and 2, with the moving pole of the switching contact 16 of the relay 3 of the clock generator 1 and through the switch 9 with the power source. Other conclusions of the blocking windings of the relay 5-8 are connected via opening the contact 17 of the relay 4 of the generator 2 of the series following periods to the common tire and the conclusions of the preparatory windings of the same relay. Other conclusions of the preparatory windings of the odd relays 5 and 7 are connected via contacts 18 and -19 of the previous even relays 6 and 8, and other conclusions of the preparatory windings of even relays 6 and 8 through the closure contacts 20 of the previous odd relay 7. The prohibiting input of the clock generator through another the closing contact 21 of the last relay 5 is connected to its input. Transistor switch 10 (11) has a control input 22 (23), an input .24 (25), and an output 26 (27). The control inputs 22 and 23 are connected to the fixed poles of the switching contact 6 of the relay 3 of the clock generator 1. Inputs 24 and 25 are connected to the input of the generator 2 of the series following up period. The output 26 of the first switch 10 is connected to the preparatory windings of the odd relays 5 and 7 connected via closing contacts 18 and 19, and the output 27 of the second switch 11 to the preparatory windings of the even relays 6 and 8 connected via the closure contact 20.

FIG. 2e designates the duration of a series of pulses, n ". ,, the duration of the pause between a series of pulses, - the period of the series, tuwn. pulse duration in the series. The distributor works as follows. At the time when the key 9 is closed, the supply voltage is applied and the relay 3 of the clock generator 1 is activated for the duration of the pulse duration tuMn. (Fig. 2a). The moving pole of the switching contact 16 of the relay 3 is transferred to another state and a control voltage is applied to the control input 23, which then opens the transistor of the switch 11 through a resistive divider and through the input 25 - output 27 preparatory winding of the relay 8 flows current. Relay 8 is activated and self-blocked by means of a closing contact 15 (Fig. 2c), and the other closing contact 19 prepares the relay 7 for operation. After time t, the moving pole of the switching: contact 16 of the relay 3 of the clock generator 1 returns to its initial state, the control input 22 receives a supply voltage which then opens the transistor of the switch 10 via a resistive divider and the input 24 - output 26 - the closing contact 19 self-blocks of rovivig relay 8 - preparatory winding of relay 7 is flowing current. Relay 7 is triggered and self-blocked by closing contact 14 (Fig. 2d and its other closing contact, contact 20, prepares relay 6 for co-operation. After a time-tMMn. Output of the clock generator 1, another pulse appears, relay 3 is activated (Fig. 2a) , the moving pole of the switching contact 16 is again transferred to another state, and power supply voltage is again supplied to the control input 23 of the transistor switch 1.1. The transistor of the switch P opens and the circuit 25 - output 27 closes the contact 20 to self-blocking relay 7 - preparer a current flows across the winding of relay 6. Relay.6 is actuated and self-blocked by means of a closing contact 13 (Fig. 2e), and its other closing contact 18 prepares relay 5 to operate. At the end of the second pulse of the so-called generator 1 the moving pole of the switching contact 16, relay 3 returns to its original state, transistor key is applied to control input 22. Transistor key 10 opens and the input 24 through output 26 is locked and contact 18 is turned off by self-locking relay 6 and the preparatory winding of relay 5 is flowing. Relay 5 is triggered and self-blocked by means of closing contact 12. Through the closing contact 21 of the activated relay 5 (Fig. 2e), the voltage is applied to the inhibitory input of the clock generator 1, which stops the generation of pulses for the time tnayi. Through time .-- Tsau. the output of the generator 2 of the period of the series is generated, a pulse is formed and the relay 4 is activated (Fig. 2b). At the same time, opening contact 17 of the relay 4 of the generator 2 of the series following sequence unlocks all the relays of the switch and the inhibiting voltage is removed from the inhibit input of the clock generator 1. At the output of the clock generator 1, a pulse appears and the process of forming the next series of pulses by means of the distributor is repeated. Thus, the switching contact 16 of the relay 3 of the clock oscillator 1 in the proposed device, which previously operated in the most demanding mode, transmits a current limited by resistive dividers (active load) in the circuit of the control inputs 22 and 23 of the transistor switches 0 and P. This the current is much less than the transistor switches flowing through the preparatory windings of the commutator switch commutator. By additionally connecting two, four, etc. serial switches to the circuit. the relay can respectively increase the number of pulses in the series to three, four, etc. The invention includes a distributor containing a clock generator and a generator of the period of the following sequence with the corresponding relays, a switch made on the relay, the leads of the blocking windings of the cohorts through the closure contacts are connected to the generator inputs, with a moving pole of the switching contact of the clock generator relay and through a key - with the power source, and other outputs of the blocking windings are connected via the disconnecting contact of the generator of the period of the next series to the common bus and the leads of the prepared windings of the relay The other side of the preparatory windings of the odd relay switch is connected through the closing contacts of the previous even switch relay, and the even relay of the switch is connected through the closing contact of the previous odd switch relay, besides the clock generator inhibitor input is connected to the other contact terminal of the last relay switch its input, characterized in that, in order to increase the distribution of the distributor, the first and second transistor 46 keys are entered into it, the control inputs of which are connected They are connected to the fixed poles of the switching contact of the clock generator relay, the inputs to the generator input of the series following period, the output of the first transistor switch is connected to the connected ones through the closing ones. the preparatory windings of the odd relay switch contacts, and the output of the second transistor switch are connected to the preparatory windings of the even relay switchboards connected via the closing contact (a.
