Description

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

The purpose of the invention is to increase the reliability of the device.

The drawing shows the proposed device.

Device for receiving signals

contains nodes 1 elect (11)

line 2 of the communication, input 3 of the node, the first relay 4 with normally open contacts 4, and normal closed contacts 4., the second relay 5 having two windings and having magnetic memory with normally open contacts 5f and normal closed contacts 52, first diode 6, the second diode 7, the third diode 8, the fourth diode 9, the third relay 10 with normally-open contacts 10 and the normal contact with the open contacts 10j.

An executive mechanism (not shown) can be connected in parallel to one of the windings of a two-winding

relay 5.

The device works as follows.

In the initial state, all elements of the circuit are canceled. To switch on the first node 1 of the election, it is necessary plus a power source to input 2, and minus to input 3. At the same time, through the diode 6 and contact 5, the first electromagnetic relay 4 will receive power. Relay 4 turns on and becomes self-blocking by contact 4 ( and breaks the power supply circuit of all subsequent nodes by contact 4. Through contact 4, the first (including) winding will receive power and the two-winding relay 5 will turn on. Relay 5, having turned on, breaks the activation circuit of relay 4 with contact, and closes the circuit for activation of relay 10 of the first node 1 After coincidence time provided for energizing the first node stops the supply of the supply voltage in lines 2 and 3. In this case, relay 4 are turned off and executive mehanizm.Rele 5 b.udet retained in closed position by the permanent magnet, not consumed electric energy.

Relay 4 is received more quickly than relay 5, and since switching on of relay 4 is not enough

if the electoral node is switched over (relay 5), then its short-term, switching on does not affect the operation of the device.

5 To switch on the elements of the second node, it is necessary to feed again plus the power supply to input 2, and minus to input 3. In this way, the elements Q of the second node will be turned on and the next node should be turned on.

After switching on the elements of the last AND -th node, it is necessary to change the polarity of the pulses of the supplying device, eg, input 2 and 3.

In this way, the second electromagnetic relay 10 and the second (disconnecting) winding of the two-winding relay 5 will be powered in the same way, producing sequential switching of the elements of the first and all subsequent nodes.

The switching circuit of each second electromagnetic relay 10 will pass through diode 7 and contact 5f of the included two-winding relay 5. Relay 10, when turned on, becomes self-locking by contact 10, and the South contact breaks the power supply circuit of all subsequent nodes. Through pin 10, the disconnecting winding relay 5 will receive power.

Relay 5, having been switched off, by pin 5 will prepare the switching circuit of the relay 4, and by the contact it will break the supply switching circuit of the relay 10.

Diodes 6 and 7 provide polar separation of the on and off signals of the two-winding relay 5

each node. 40

Diodes 8 and 9 and their corresponding installation provide a stable connection in a predetermined sequence, first relay 4 (10), and then

 relay 5.

For normal operation of the circuit, it is necessary that the duration of the supply voltage pulses be longer than the turn-on time of the electromagnetic relay 4 (10) and the switching of the two-winding relay 5, and the duration of the pause between pulses must be longer than the turn-off time of the relay 4 (10).

55 To orient the device in the output state, it is necessary to input a certain number of supply voltage pulses to the inputs 2 and 3

The polarity of which is determined by the position of the contactor of the double-winding relay 5.

As a double-winding relay 5, a remote switch with magnetic memory was used, and as a Editor M. Bandura

A and 10 relays are high-speed low-current electromagnetic relays.

Thus, when applying clock pulses of a voltage of a certain polarity to inputs 2 and 3, the elements of the nodes are turned on and off in series.
