In my mom’s office I noticed a component was installed to the ceiling, and I just realized that its tiny LEDs would turn on for a sec and as I counted it had a time delay of 12 seconds ( probably)

[@yelloweater5506]

And also I see that you almost turned analog signal of capacitor into digital by the transistor.

writing this comment while the add is still running, i like your choice of fields you cover! one by one you explain all the stuff in detail and every question i still have left gets awnsered!! you rock man!!

For my final exam in my journeyman Final exam after six years of studying to get my electrical license! I built a time delay project from start to finish with all the bells and whistles! It worked thank goodness!

I will put a time delay relay to delay starting of a vent fan until the duct damper has opened. Thanks for the clear explanation!

[@jlaustill]

I used a time delay relay in my pickup so the auxiliary power stays on for 2 minutes after turning the key off like newer vehicles. I also made it turn the overhead lights and outside lights on when the key is turned off. Works great

[@tangaajah1604]

I must give you 5 stars sir, is amazing, easy, understandable.

[@Gomepez]

Thanks for the expanation! Im going to delay the power cut to my car radio after the ignition power is cut. Music can keep playing for 10-15 seconds after shutoff so I can walk away in style.

[@allmightjunior6917]

This circuit is brilliant, thanks for the video

[@heatsingh2205]

I have been using time delays in controll panels to adjust the switch of timing when energized by a limit switch we use select timers heavy duty

[@yimmygomez7173]

I find these videos SO useful! I work with these kinds of components all the time. Do you think you could explain the theory of operation of saturable reactors? I work with them, and so far every explanation on KZbin or Google has left me just as confused. Thanks! And keep up the good work!

[@Richie_]

I was a machine setter and our rotary transfer machines had loads of relays. Wurth & Gruffat machines. I was a trainee at the time and didn't know much about them as the only one ever changed was the cycle time relay.

[@geetacreation5731]

YOUR EXPLANATION WAS ASOME 👌🏻👌🏻 Sir you do video about CD4017

[@Elfnetdesigns]

Time delays are used in modern US locomotives to control the ditch light flasher when the horn button is pressed, these are usually integrated into the whole light system though, however older locomotives owned by shortline railroads retrofitted to FRA guidelines use separate control devices for flashing and delays rather than a whole new system. Another place where time delays and relays (namely solid state relays) are used is in communications tower beacon flasher circuits.

[@mrwendell4564]

Older FAUs use a 24volt time delay relay powered by a small heat motor that produces heat and warms up a bi-metal which warps and closes the switch for the 120volt blower fan. Very cool and intricate stuff

[@coldfinger459sub0]

Excellent presentation and gradual increase in knowledge how every component interact with each other. This kind of knowledge used to be taught in middle school electronica class. Nowadays a student has to elect to take a electronics class in college by choice to get this knowledge.

[@davidmoran4471]

A company where I worked built a training simulator for a ship console. This required several industrial computers to control the console, the switching power supplies of the computers act as a direct short, momentarily, so a number of delay relays were utilized to sequence the computers startup.

[@schweizerd6303]

one place I ran across an RC timer delay circuit was on an old haunted Otis lift located at an UK motorway service station (the one with the abandoned restaurant on top that looks like two small out-of-proportion towers after the government imposed height restrictions), the circuit was supposed to time how long it keeps the door open but the capacitor was probably leaking which prematurely caused activation of the Door Close circuit, thus when someone presses the hall call button, the lift doors open half way then immediately slams shut, it was an extremely creepy lift!! used to give me nightmares of ghosts and demons luring me into that lift then being pinned and injured badly by the force of the slamming doors and then crushed and sliced in half when the lift starts to move, that's when I wake up sweating and heart racing, and yes that lift was all controlled by relay logic you can even hear all the relays clicking, keep pushing any buttons over and over and you will hear the relays click away if you are close enough to the top floor where the machine room is

I have seen these in an operational and maintenance capacity at Water/Sewerage Pumping Stations within their Cupboards/Closets and at Power Distribution Rooms for WTPs and WWTPs for various MOs.

[@PunakiviAddikti]

I've seen these timing relays in school bathrooms. A PIR sensor actuates the relay and it remains on for a while. Eventually it turns the light off. The lights didn't have repeat actuation (meaning the timer will reset every time the PIR senses motion). Instead the timer has to run out before the PIR can detect motion again. I'm pretty sure the relay is built into the PIR sensor module, but it has a loud, distinct click.

[@prettycureforever7102]

For hvacr you can put a time delay for the fans so the coil will have time to reach a certain temp before turning on the fan

[@hatsuwr]

Or to just reduce the peak startup current by starting the compressor first, then the fan.

I use time delay relays in multiple 12V DC application to prevent voltage spike from damage the sensitive controllers. To do this I've added one to the start of the unit to give it a 10 - 20ms delay before powering the system, that way it give me enough time to make a proper contact before the in rush current comes, other if it's instant the in rush current will cause an ark, which will damage the sensitive unit. The time delay relay has save me multiple units and is adjustable, that way I'd know for sure my circuit will be safe from a in rush spike.

[@sakibthakor897]

Amazing bro plzz make videos on smd device

[@jeffreyhueseman7061]

I've seen these used in control panels for hospitals for preventing short-cycling of equipment as minimum run timers, stagger the starting of equipment to prevent excessive current draw, allow equipment to switch to auxiliary power after the generator gets up to operating speed and to keep sensitive equipment from tripping alarms.

[@EngineeringMindset]

[@GeoffCostanza]

I was the 1000th like. That's pretty exciting.

[@TheVDentertainment]

I watched the video and I really liked it. :) Just a question... it it possible that the animation at 1:48 marked wrong? I mean... it seems that the "delay off" has the delay on's animation. Im asking cuz im about to bulid something which is needs a delayed on function.... so after I push the button the electricity should wait at least 1 sec before began to flow. :) Which one do I need then?

[@yottawatts9470]

At 8:43 would the power source continually charge the capacitor keeping the circuit closed indefinitely? Would there need to be a switch to remove the capacitor from the circuit after it was charged? (e: The path was shown in conventional which threw me off a bit, but there is still a main path through the circuit to charge the capacitor, perhaps it discharges faster than it charges causing voltage to drop below the setpoint needed which would be the timer.)

[@sufyanparkar9790]

You're the Best

[@italianstallion69420]

11:01 In this example, does an increase in capacitance for the capacitor lead to an increased amount of time before the light is electrified?

[@wzpu3283]

Yes, I think you are correct.

[@MaxPowerElectric]

Since you did a few automotive videos recently-- are time delay relays used in cars to control interior lighting? (ie. lights turn on when doors are opened, but turn off after a period of time)

[@EngineeringMindset]

Yes, that's a good idea they could be used

[@Echo51]

It can be, but generally it's all done electronically with a programmable timer in the body control module

Hi James, check this out: www.tele-online.com/en/produkt/e3zi20-12-240vac-dc/ This item makes sure that your compressor is running for e.g. 5hrs and then pauses for one. Commonly used to cyclically get rid of vaporized water in the compressor system
