Timer Plus Relay by IC 555

This be Timer Plus Relay Circuit by IC 555. When see the circuit also a little equipment. By the value R1 and C1 perform set the time give Relay work 11 long ago second. When we begin to encourage the circuit by switch press 2 pin with a leg Ground note: Relay 6V 500ohm. Use current 12mA. The detail is other , see in the circuit adds.

simple timer with IC 4093 + 7808
The on time of the timer is set by the one shot built with R2/R3 C3 and IC2A: after pressing pushbutton S1 C3 will be charged slowly through R3/R2; as long as the voltage of C3 is below the schmitt trigger trip level, the output of IC2A will be high and the the relay is switched on. Alt ...
Relay Timer switch By IC 555 and 741
In Fig.1 see a 100 second delayed turn ON relay RL1 switch, if plug power +12V in circuit. In Fig.2 see a two range 6-60 second and 1-10 minute auto turn off relay timer circuit, with 555. Part R1=1 Mohms C4=100nF 63V IC2=LM555 R2=330 Kohms C1-2=100uF 16V RV1=470 Kohm ...
Long Time Delays by CD4040
Generating long delays of several hours can be accomplished by using a low frequency oscillator and a binary counter as shown below. A single Schmitt Trigger inverter stage (1/6 of 74HC14) is used as a squarewave oscillator to produce a low frequency of about 0.5 Hertz. The 10K resistor in s ...
de luxe timer with IC 4093 +7808
The "de luxe" schematic makes use of all four schmitt trigger nand's of the HEF4093 IC The on time is set by the one shot built with R2/R3 C3 and IC2A: when the pushbutton is depressed C3 will be charged slowly through R3/R2; as long as the voltage of C3 is below the schmitt trigger trip lev ...
Basic Timer Control with NE555
As friends many take an interest the circuit about IC 555 which be integrated highly popular that circuit. I then lead the circuit sets the time be Basic Timer Control with NE555 come to present again. By it basically the base of the circuit sets the time work instruction easily in ...
