Description

The invention relates to a pulse technique and can be used in various devices of discrete automatics,

The purpose of the invention is the expansion of functional capabilities due to the formation of output pulses on both the leading and trailing edges of the trigger pulse.

The drawing shows the principle of the electrical circuit, the counting trigger.

The counting trigger contains a two-booster relay 1 with self-holding with the first 1.1 and second 1.2 windings and interconnecting contact groups 1.3 and 1.4, a two-winding ryte 2 with self-removal, with a first 2.1 winding and a second 2.2 winding two-winding relay 3 with switching contact -sh group-- mi So1 and 3.2. The first output of the winding 1.1 through the opening contact group of the switching contact group 3.1 is connected to the capacitor 4,

The first output winding 1.2 through size 1 25 group 3.2, capacitor 5, winding

the contact contact group of the switch, the contact group 3.2 is connected to the capacitor 5. The closing contacts of the contact groups 3.1 and 3.2 are connected to the corresponding fixed contacts of the contact group 1.3, the switching contact of which through the diode 6 is connected to the output 7 and the first winding terminal relay 3, second

2.2 self-holding two-winding relay, bus 8 triggers double-winding polarized relay 2, its contact group is switched. With this, the capacitor 5 is charged until the voltage of the power source. After charging the capacitor 5, the consumed current in winding 2.2 is absent. When removed from the control 7, the first terminal of which is connected; with a length of 35, the single-winding relay 3 is released, its contact groups 3.1 and 3.2 of the contacts return to their original state. However, from this moment of time, the charged capacitor 5 starts switching off the winding 1.2 of the double-winding relay 1 through the switch-disconnecting and opening contacts of the contact group 3.2, and the contact groups 1.3 and 1.4 switch over. In dunneigam, the cycles of the counting trigger are repeated. The output signals of the counting trigger are formed on the I free groups of double-winding relays 1 and 2, on the first of which the signal changes state on the falling edge of the pulse, and on the second, on the leading edge.

8, which is connected via winding 2.i with the second output of the capacitor 4 and the second output of the winding S. 1., And through the winding 2.2 - with the second output of the capacitor 5 and the second output of the winding 1, 2.

The counting trigger works as follows.

When the impulse control relay 3 is applied to the busbar 7, the opening contacts of the contact groups 3.2 and 3.1 open, and the closing contacts close, along the circuit: 7, diode, b, the opening contact group of the contact group 1.3, the closing contact group of the contact group 3.1, the capacitor 4 is a winding 2.1 of the relay, the bus 8 triggers a double-winding polarized relay 2, its contact group switches from, and the capacitor 4 is charged before the voltage of the power supply. After termination of charge of the condenser

4 noTpe6jteHHe current on the winding 2, 1 is missing. When the first pulse of the first pulse is removed from the control bus 7, the one-turn relay 3 is released, its contact groups 3.1 and 3.2 of the contacts return to their original state. However, from this moment on, the charged capacitor 4, through the switching and closing contacts of the contact group 3.1, begins to unload on the winding 1.1 of the two-winding relay 1, which causes it to operate, and the contact groups 1.3 and 1.4 switch.

When a second control pulse is applied, the relay 3 triggers again, its contact contacts of contact groups 3.1 and 3.2 open, and the closing contact 1 1 closes, and the bus 7, diode 6, switching contact of contact group 1.3, and switching contact contact groups 1, 3, closing contact contact group 3.2, a switching contact contact

2.2 self-holding two-winding relay, bus 8 triggers double-winding polarized relay 2, its contact group is switched. In this case, the capacitor 5 is charged before the voltage of the power source. After charging the capacitor 5, the consumed current in winding 2.2 is absent. When the first winding relay 3 is removed from control 7 of the first, its contact groups 3.1 and 3.2 of the contacts return to their original state. However, from this moment of time, the charged capacitor 5 starts switching off the winding 1.2 of the double-winding relay 1 through the switch-disconnecting and opening contacts of the contact group 3.2, and the contact groups 1.3 and 1.4 switch over. In dunneigam, the cycles of the counting trigger are repeated. The output signals of the counting trigger are formed on the I free groups of double-winding relays 1 and 2, on the first of which the signal changes state on the falling edge of the pulse, and on the second, on the leading edge.
