Description

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

The purpose of the invention is to increase the speed and reduce the power consumption of the relay trigger by eliminating the resistor and the resistance of the remote switch from the capacitor charge circuit.

The drawing shows a schematic diagram of the relay trigger.

Relay trigger contains two-winding relay (switch) 1 with self-holding, first and second capacitors 2 and 3, disconnecting, closing and switching contacts 4, 5 and 6 of two-winding relay 1 with self-holding, first and second diodes 7 and 8, first bus 9 power, the first and second additional diodes 10 and 11, the control key 12 with switching, opening and closing contacts 13, 14 and 15 and the second power bus 16.

The first terminals of the windings of the remote switch 1 through the first and second capacitors 2 and 3 are connected to the opening and closing contacts 4 and 5 of the remote switch 1, which are connected through the first and second diodes 7 and 8 of opposite polarity of the supply voltage to the first bus 9 power supply, to which the switching contact 6 of the remote switch 1 is connected, the switching contact 13 of the control switch 12 is connected to the second terminals of the windings of the remote switch 1, the closing contact 15 is connected to the first power supply bus 9, I open A common contact 14 is connected to the second power bus 16, and the first and second additional diodes 10 and 11 are connected in parallel to the first and second windings of the remote switch 1 according to the polarity of the supply voltage.

The device works as follows.

When power is applied, one of the capacitors 2 or 3 is charged depending on the position of contact 6 in the circuit: bus 9, closed contacts 6 and 4, capacitor 2, diode 10 VNIIPI Order 300 /

pins 13 and 14 of the control key, bus 16.

When the control key is switched (contact 13 opens with contact 14 and closes with contact 15), the charged capacitor is discharged by winding the relay, which causes switching 6 of the remote switch 1. When the control switch returns 1, the key returns to its initial position capacitor charge 3.

When the control key is switched again, the charged capacitor is discharged through the elastic winding of the remote switch 1, which switches to the initial state shown in the drawing.

Upon further switchings of the control key, the cycle of operation of the device is repeated.

To limit the charging currents of the capacitors, a current limiting resistor (not shown
