Description

one

This invention relates to automation and computing. The switch can be used in output devices that control high-current circuits with currents of various kinds, where memory of previous states is required.

A relay switch is known that contains control regions that control relays that are connected via two contact groups to switching cells, each of which consists of two relays having four contact groups (three normally open, one normally closed).

However, the known device does not allow switching the circuits in a random order and for a long time to block (remember) previous states of the relay.

The purpose of the invention is an arbitrary sampling of switched circuits and memorization of previous states.

The proposed switch is characterized in that the first contacts of three normally open groups of one relay are connected to the first contacts of normally open groups of the other, and the second contacts of the first normally open groups of both relays are connected to the ends of the windings of their other relays connected to control shi2

us, and the other ends of the windings are connected to the first pins of the second normally open groups, the second pins of which are connected to each other and to the common length, to which the first pins of the third normally open groups are connected.

The drawing shows a circuit diagram of the device.

The switch contains control areas

li-U, control relays, switching cells 3i-3;,. each pz of which consists of two relays 4), 42, Relay 2i has normally closed contacts 5–62 and normally open contacts 5з, 64; Relay 4i has four contact groups on pins 6i-63 and two contacts bd, by-winding pins; similarly, relay 42 has contacts 7; -7s and 7d,. Relay 2p + 1 has normally closed contacts 8i, 82. In addition, the device contains

Inputs 9i-9n-s, and each of the cells 3i-3, g has outputs 10, South.

In the initial state, all the relays of each cell are de-energized. With simultaneous operation of the relay 2

and supplying a short-term voltage to the busbar, the relay 4i is turned on via the rod b and contacts 5, 64. In this case, relay 4i enters self-locking mode through contacts 8i, 82. Contacts 6i, 62, contacts 7, 74 relays

42, its contacts 65, 6b and contacts 5z, 64 relays 2i, contacts 6z, 64 relays 4i and contacts 5 Sj of relay 2i open.

A circuit connected to the output lOi, supplied from a direct current source, is closed through closed contacts bt, bz of relay 4i. After removing the voltage from the bus li and de-energizing relay 2i, relay 4i remains in the on state.

When a relay 2i is triggered simultaneously and a short-time voltage appears on bus C of relay 42, the circuit 42 switches on: bus b, winding relay 4z, contacts 5, 5 relays 2, button I, ground. Contacts 7z, 74 in the power supply circuit of relay 4i are opened, and the circuit connected to output 102, supplied from an alternating current source, is closed through closed contacts 77, 7s. After removing the voltage from the bus li and de-energizing relay 2i, relay 42 remains in an on state.

At the simultaneous operation of the relay 2i and relay 2p + 1, contacts 5i, 62 and contacts 8i, 82 open. Relay 4i or 42 de-energizes and output contacts 67, without or 77, 7s open. Thus, both switching circuits switched by this cell open.

Pressing the button 11 de-energizes all switch cells, i.e., sets the initial state.

According to the relay number 2i-2 „, the switch cells are sampled.
