CO The invention relates to automation and can be used to control objects that operate sequentially one after the other in time. A known distribution relay switch containing two power supply lines, dialing nodes, each of which is equipped with two electromagnetic relays and diodes, i The disadvantage of the relay distributed switch is a high electrical energy consumption, depending on the number of electors involved. The closest in technical essence to the present invention is a device for receiving signals, comprising nodes each of which is selected on the first relay and the second relay with magnetic memory, the first input of the device through serially connected diodes, the windings of the second relay and the first relay contact of the first relay the first node of the election is connected to the second input of the device and to the first output of the winding of the first relay; the first input of the device is connected through a parallel-connected chain of a diode and the first terminals cycles of the second relay of the first node of the election is connected with the first conclusions of the diodes of the next node of the election 2. A disadvantage of this device is the inability to force synchronization of switching of the nodes of the election, which limits its scope. The purpose of the invention is to expand the field of application of the device. . This goal is achieved by the fact that the device for receiving signals containing series-connected electoral nodes, X1 each of which is made on the first relay and on the second relay with magnetic memory, the first input of each node is selected through series-connected diodes, windings of the second relay and the first contact the first relay is connected to the second input of the electoral node and to the first terminal of the winding of the first relay; the first input of the electoral node through parallel middle chains of series-connected diode and first the contacts of the second relay of the first node of the election are connected to the first terminals of the diodes of the next node of the election; the second and third contacts of the first relay are entered into the nodes of the election; the second output of the first relay is connected to the first input of the node of the second relay through the second contacts of the second relay connected to the middle points of the chains of a series-connected diode and the first contacts of the second relay, the second input of the electoral node through the trip the third contacts of the first relay connected to the second input follow this knot elect. The drawing shows a diagram of the device. The device for receiving signals contains the first electromagnetic relay 1 and the 1, 1 and disconnecting C contacts, a two-winding relay 2 with magnetic memory and its 2, 2 and locking 2, 2x relays. contacts, nodes 3-5 elect, the first 6 and second 7 inputs, diodes 8-11. An actuator (not shown) can be connected in parallel to the winding of the electromagnetic relay 1. The device1) operation operates as follows. In the initial state, all circuit elements are disabled. To turn on the first node of election 3, the necessary power supply source is applied to input b, and minus - to connect output 7. At the same time, through the diode 10, the break contact 22, the actuator and relay 1 will receive power. Relay 1,. when turned on, it becomes self-ignoring. contact 1, contact 1 closes the power circuit of the turn-on winding of the (first) two-pin precision relay 2, and contact Lj breaks the power circuit of the second electoral unit 4. Relay 2 turns on and prepares the turn on circuit of the second node 4 of the election by contact 2, and contact 2 l breaks the preparation circuit for turning on the relay 1 of the first cell of election 3. After the time stipulated for turning on the first actuator has expired, the supply voltage to buses b and 7 stops. In this case, the actuator is disconnected and the relay 1. Relay 2 will be held in the on position by a permanent magnet, not consuming electrical energy. To turn on the elements of the second electoral node 4, you must again submit the plus power source to input b, and the minus to input 7. At the same time, the executive mechanism will turn on and prepare circuits for switching on electoral units of the third electoral node. After switching on the actuator of the last node of the election, the polarity of the pulses of the supply voltage supplied to inputs 6 and 7 must be changed. In this case, the preparation circuit for switching on each relay 1 will pass through diode 11 and pin 2 of the two-winding relay 2. The voltage is opposite

the polarities supplied in this way to the disconnecting (second) winding of the ffeyx winding relay 2 disconnects the relay 2 which, in turn, prepares the turn-on circuit for the next dialing node, etc. by contact 2.

For a normal function of the circuit, it is necessary that the duration of the supply voltage ttulsi be longer than the turn-on time of the relay I and the switching of the two-winding relay 2, and the duration of the pause between the pulses must be greater than the turn-off time of the relay 1.

To orient the device to its original state, it is necessary to apply a certain number of supply voltage pulses to the inputs 6 and 7, field p

whose strength is determined by the position of the contacts of the relay 2.

 Thus, when clock pulses of a certain polarity are applied, inputs 6 and 7 sequentially turn on and off elements of the dial-up nodes.

The supply of each node of the device I election, which has two inputs and a two-winding relay with magnetic memory, an electromagnetic relay with additional contacts allows expanding the device's three-meter area using it in the receiving and transmitted to the semi-sets of the telemechanics system with forced syn- chronization of the switching of the voting nodes.
