Description

The invention relates to automation and telemechanics and can be used to control objects that operate sequentially one after the other in time, and is an improvement to the device by author. No. 1211781.

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

The drawing shows a circuit diagram of the device.

The device for receiving signals contains: election nodes 1 (1, ..., p), inputs 2 and 3 nodes, the first relay 4 with normally open contacts 4, and normally closed contacts 42, the second relay 5 having two windings and having magnetic memory with normally open contacts 5, normally closed contacts 5 "and additional contacts 5j located in the subsequent nodes of the election, diodes 6-9, third-relay 10 with normally open contacts 10 and terminal closed 10

An actuator (not shown) can be connected to the mains using the power contacts of relay 5 (not shown).

The device works as follows.

In the initial state, all elements of the scheme are disabled. To turn on the first node of the election, it is necessary + to supply the power source to input 2, and - to input 3. At the same time, the first electromagnetic relay 4 of the first election node is supplied through diode 6 and contact 5. Relay 4 ON

Having become, it becomes on self-blocking by contact 4, and by contact 4 it breaks the power circuit of all subsequent nodes. Through pin 4, the winding receives power from the first (including) and turns on the double-winding relay 5. Relay 5, having turned on, by contact 5, breaks the preparation circuit for switching on relay 4 and closes the preparation circuit for switching on relay 10 of the first election node 1, and 5 prepares the enable circuit of the second election node 1. After the time provided for switching on the first node has expired, the supply of supply voltage to inputs 2 and 3 is stopped. At the same time, relay 4 is turned off. Relay 5 is kept turned on by a permanent magnet, not consuming electrical energy.

To switch on the elements of the second node, it is necessary to feed again + the power source to input 2, and - to input 3 ". In this way, the elements of the second node are turned on and the switching-on circuits of the subsequent node are prepared.

After switching on the elements of the last nth node, it is necessary to change the polarity of the supply voltage pulses to inputs 2 and 3.

In this way, the second relay 10 and the second (disconnecting) winding of the relay 5 are similarly powered, sequentially switching elements of the first and all subsequent nodes.

The switching circuit of each second relay 10 passes through diode 7 and ends

step 5) relay 5. Relay 10, when turned on, becomes self-blocking by contact and contact lOg breaks the power supply circuit of all subsequent nodes. Through the contact 10j, the disconnecting winding relay 5 receives power.

Relay 5, (disconnecting by pin 52, prepares the turn-on circuit for relay 4, by pin 5 breaks the turn-on preparation circuit of relay 10, and by pin 5d it prepares the turn-off circuit for the next electoral unit.

switch two winding relay 5 each node.

Diodes 8 and 9 provide a stable connection in the specified 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 relay 4 (10) and the switching of relay 5, and the duration of the pause between pulses must be greater than the turn-off time of relay 4 (10).

To orient the device to its original position, it is necessary to apply a certain number of supply voltage pulses to inputs 2 and 3, the polarity of which is determined by the position of the contacts of relay 5. - The remote switch with magnetic memory is used as relay 5 and the relay 4 (10 ) is a low current magnetic relay, and no conditions are imposed on the speed of the relay.

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

Due to the fact that with each clock pulse, the voltage is applied only to one relay 4 (10), a powerful power source is not required and no conditions are imposed on the speed of the relay.
