Description

The invention relates to automation and telemechanics and can be used to control a large number of control objects operating sequentially one after the other in time.

The purpose of the invention is to simplify the device.

The drawing shows a schematic diagram of the device.

The device contains nodes 1,,, .., 1 elections, each of which contains a relay 2 with a closing contact 2, and an opening contact 2j, a relay 3 with a closing contact 3, and with a breaking contact 3, diodes 4-7, lines 8 and 9 communications.

The device works as follows.

In the initial state, all circuit elements are disabled. To enable the first node 1 (elect to

line 8 is communication, and minus is at line 9 of communication. At the same time, relay 2 is turned on. Relay 2 turn on circuit: plus power supply - relay 2 winding, first winding 3 - diode

The switching on circuit of the relay 2, in this case, passes through the contact 3, the diode 7 and the second winding of the relay 3. Once turned on, it becomes locked by contact 2j through g 6, and the contact 2 breaks the power supply of all subsequent nodes and wounds. Through pin 2 and diode 6, the power is supplied to the second winding, which, having turned off, prepared the switch-on circuit of relay 2 through contact

food chain of all subsequent nodes of the election. Through pin 2 (and the diode 5 receives power, the first winding of the relay 3 and it turns on. Relay 3, having turned on, contact 3j, breaks the preparatory circuit Q for switching on relay 2 of the first node of the election through diode 4 n and prepares the turn-on circuit for relay 2 through pin 3 and diode 7, After expiration

Diodes 4 and 7 provide field separation of the switch-on signals for each node in the election. Diodes 5 provide switching on and off of the two-winding relay 3 of each at the election and self-blocking of the relay with different polarity of the applied voltage.

 For normal operation of the circuit, it is necessary that the duration of the impulses of the supply voltage b is longer than the turn-on time of the relay 2

In order to switch on the elements of the second election node, it is necessary to submit again the plus power source 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 switching circuits of the next election node are prepared.

After switching on the elements of the last node of election, it is necessary to change the polarity of the supply voltage pulses.

In this case, the power is supplied to the relay 2 and the second winding of the relay 3 produces sequential switching of the elements of the first and all subsequent nodes of the election.

The switch-on circuit of relay 2, in this case, passes through pin 3, diode 7 and the second winding of relay 3. Relay 2, when turned on, becomes self-locking by pin 2j through diode 6, and pin 2 breaks the power supply circuit of all subsequent electoral nodes. Through pin 2 and diode 6 it receives power from the second winding of relay 3, which, having switched off, prepares the switching circuit of relay 2 through contact

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

 In order for the circuit to function normally, it is necessary that the duration of the supply voltage pulses be longer than the switching time of relay 2 and ne

the time provided for switching on the 45 relays of the relay 3, and the duration of neither the first electoral unit, the interruption of the pause between pulses should be

more time off relay 2.

In order to orient the device, it is necessary to apply a certain number of supply voltage pulses on the line 8 and 9 of the communication, the polarity of which is determined by the position of the contacts of the two-winding

The supply voltage to the inputs is protected. The relay 2 and the actuator are disabled. Relay 3 is held in the on position by a permanent magnet, without consuming electrical energy.

Relay 2 is assumed to be faster than relay 3, and since the switching on of relay 2 is not a sufficient condition for switching the electoral unit (relay 3), its short-term activation does not affect the device's operation.
