The invention relates to a pulse technique and can be used in various systems of discrete automation.

The purpose of the invention is to reduce power consumption by eliminating a resistor, in series with the relay coil, and increasing reliability by ensuring that the elements operate at a lower voltage.

The drawing shows a schematic diagram of a relay trigger.

The trigger contains the first relay 1 with the closing and switching terminals 2 and 3, the second relay 4 with the closing terminal, switching and opening contacts 5 and 6 and 7 of one of its groups and the closing and switching contacts 8 and 9 of its other control relay group 10 with the closing and switching contacts 11 and 12 of one of its groups; switching and disconnecting contacts 13 and 14 of its other group; and switching and closing contacts 15 and 16 of its third group, resistor 17, lockable thyristor 18, first and second power bus 19 and 20.

In a relay trigger containing a resistor 17 and the first and second relays 1 and 4, the first winding pins of which are connected to the first power bus 19, to which the first pin 5 of the first group of the second relay 4 is connected, the second winding pin of which is connected to the second power bus 20 through the closing and switching contacts 8 and 9 of its second group and the closing and switching contacts 2 and 3 of the group of the first relay 1, parallel to the group of the first relay are the penitent and switching contacts 11 and 12 of the first group of the control relay 10, which opens and switches pins 14 and 13 of the second group of which are connected in parallel to the closing and switching contacts 8 and 9 of the second group of the second, lockable thyristor 18 is inserted, the cathode of which is connected to the second terminal of the winding of the first relay 1, the anode to the second power bus 20, the control electrode through switching and closing w; The third contacts 15 and 16 of the third control group are connected to the switching contact 6 of the first group of the second relay 4, opening: contact 7

which through a resistor 17 is connected to the second power bus 20.

The trigger works as follows.

5 In the initial position, the trigger is in one of the stable states and does not consume energy, since the windings of relay 1 and 4 are disconnected from the power rails and the winding of relay 10 does not receive an input signal.

When the relay 10 trips, contacts 15, 16 and 11, 12 close, contacts 13, 14 open. The thyristor 18 is turned on, turning on the relay 1 winding. When the relay 10 is lowered, contacts 15, 16 and 11, 12 open, contacts 13, 14 close, relay 4 operates, contacts 5, 6 and 8, 9 close. Trig2 switch turns into another steady state.

The next time the control relay 10 is activated, contacts 11, 12 and 15, 16 close. The thyristor 18 is turned off,

25 disconnecting the winding of the relay 1 from the bus power-HP1Ya. Relay 1 is turned off. Relay 4 remains in the activated state, since pins 11, 12 and 8, 9 are closed. If the relay 10 is released, the relay 4 is de-energized, the trigger returns to the output30
