sequentially one after the other in time, the purpose of the invention is to increase speed and reduce energy consumption. A device for receiving signals contains election nodes, each of which contains a relay with closing and opening contacts and with a switching contact group included in the next measurement node, diodes and communication lines. Due to the fact that with each clock pulse, the voltage is applied only to one relay, a powerful power source is not required and no relay speed requirements are imposed.1 silt.

The invention relates to automation and telemechanics, can be used to control objects that operate sequentially one after the other in time, and is an improvement of the device by AB. No. 1282182.

The purpose of the invention is to increase speed and reduce energy consumption.

The drawing shows a circuit diagram of a device for receiving signals.

A device for receiving signals contains nodes 1 election (1 ...... p), each of

which contains relay 2 with closing contact 2ι and disconnecting contact 2g, relay 3 with closing contact 3ι and with disconnecting contact For and with a switching contact group Z3, included in the next measurement node, diodes 4-7, lines 8 and 9 of communication.

The device works as follows.

In the initial state of the expert circuit elements are disabled. To enable the first

Node 1 of the election requires the “plus” of the power source to be supplied to the communication line 8, and the “minus” to the communication line 9. This switches on the relay 2. Relay 2 turn-on circuit: “plus” of the power supply - relay 2 winding - the first winding of the relay 3 - diode 4 - contact Cr - line 9 connection - the "minus" of the power source. Relay 2, having turned on, becomes self-blocking by contact 2ι through diode 5, and by contact 2g it breaks the power supply circuit of all subsequent electoral nodes. Via contact 2ι and diode 5, the first winding of relay 3 is energized, and it turns on.

Relay 3, having turned on, by contact Zg, breaks the preparation circuit for switching on relay 2 of the first election node through diode 4 and prepares the switching circuit of relay 2 through contact 3ι and diode 7, contact Z3 prepares the switching circuit for the second election node. After the expiration of the time provided for the inclusion of the first election site, the supply of supply voltage to the inputs is terminated. This turns off relay 2. Relay 3 is held in

on with a permanent magnet, without consuming electrical energy.

The actuator (not shown) can be connected to the mains using the power contacts of relay 3 (not shown).

Almost no conditions are imposed on the speed of the relays used.

To turn on the elements of the second election node, it is necessary to re-supply the power supply plus to the communication line 8, and the minus to the line 9. In this way, the elements of the second node are turned on and the next election node is prepared.

After switching on the elements of the last election site 1, the polarity of the supply voltage pulses must be changed. In this case, the power is supplied to the relay 2 and the second winding of the relay 3, producing successive switching of the elements of the first and all subsequent electoral nodes.

The switch-on circuit of relay 2 in this case passes through pin 31, diode 7 and the second winding of relay 3. Relay 2, when turned on, becomes self-blocking by pin 21 through diode 6, and contact 2g breaks the power supply circuit of all subsequent electoral nodes. Through'contact 2ι and diode 6 receives power the second winding of relay 3, which, having been disconnected, prepares the turn-on circuit of relay 2 through pin Zg and diode 4, and contact 3ι breaks the preparatory circuit for switching on relay 2 through diode 7, contact Z3 prepares the turn-on circuit of the second node election.

Diodes 4 and 7 provide a polar separation of the switching signals of the relay 2 of each node of the election. Diodes 5 and 6 provide switching on and off of the two-winding relay 3 of each node of the election and self-blocking of relay 2 with different polarity of the applied voltage.

For the normal operation of the circuit, it is necessary that the duration of the supply voltage pulses be longer than the time for switching on the relay 2 and switching the relay 3, and the duration of the pause between the pulses must be greater than the switching off time of the relay 2.

To orient the device, it is necessary to apply a certain number of supply voltage pulses on the communication lines 8 and 9, the polarity of which is determined by the position of the contacts of the two-winding relay 3.

Due to the fact that with each clock pulse the voltage is applied only to one relay 2, a powerful power source is not required and no conditions are imposed on the speed of the relay.
