Building Basic Ladder in Automation Studio with Relays
มุมมอง 4.1K2 ปีที่แล้ว
Drawing a basic ladder logic circuit with Automation Studio. The circuit contains memory latches and the basic counter which allows a single push button to turn on a lamp and when pressed a second time we'll turn off the lamp. This is a good example of ladder logic programming that has a single event, such as a push button being pressed, that does a different thing to the circuit the second tim...
Intro to Timers Humber Labs

This video discusses how timers work. It includes both On Delay and Off Delay timers. I use several circuits and discuss different applications. In the last part of this video, I discussed different ladder design options to solve a problem using timers.

Thank you very much, it cleared my confusion hehe
I read through a couple PLC manuals and always struggled with how to read the ladder diagram. This made everything very clear. Thank you!
Wow thank you you saved my life
I gotta watch this a few more times 🎉🎉
Hope you’re still out here Lars. Thanks
Yup, I'm still in the loop. Unfortunately, I haven't been able to fit in producing videos for a few years now. I took a distracting new job at my Collage a few years ago and I miss doing videos, but I’ll come back into the scene in a while. I dream of making SO MANY awesome videos all the time and I’m also in the process of designing a new TH-cam studio AND I have an interactive projector and a new place for my studio, so one day… Thanks for the comment
@@larsexplains3086 thanks for replying. I really like the “ controls” vids….relays timers etc. it’s appreciated. Good things to ya!
You're quite helpful.
they are in different rungs, with address, those three rungs are separeted circuits cannot influence each others.
The way this guy talks is radical.
True is 1 closed contact, false is 0 open contact?...?
Yes.
unfortunately i wanted to see in ladder logic the stop button, some videos in that configuration they program it as NO, i simulated it with the zelio as NC and it works fine.
Love this.
I hope you see this but I’m in school right now and my instructor won’t explain things to us. This video and all your other ones have saved me a lot of frustration THANK YOU
man ,wish i had you as my motor controls class instructor back in the early ‘90’s
🤣 I'm happy I can learn you real good!
So nice thanks sir
Why does every one explain the circuit that you should not use in a car or any other machine?
i need a power circuit for the mix of two liquids
thanks well explained ❤
well explained thanks 😊
at 14:04 I believe T stands for temperature in the formula gas law, not time (t)
❤❤❤❤ Great
Was looking for videos on latching relays but this helped certain applications make more sense. We use a start and stop button for our motor starters and I always kinda wondered how just a N.O contact would keep it energized after you release the button
confusing but i get it 🤣🤣🤣🤣
thank you saving me from 3 hours of studying, god bless you
Hello thank you very much for your explanation. but do you think a over drive factor (ODF) of about 2 for this matter is really enough?
Hello there, we have problems with Voltage fluctuations, where the voltage dips briefly and then comes back on right away. This causes my AC compressor many problems, so I installed a ICM Delay on Make Timer. The strange thing is that the timer does not cut out at those dips but only delays once the electricity goes off completely ( same counts for the built in delay in my Air handler thermostat). So here my question : would a Ditek Surge Protector be a solution or do I need to install something else ? Thank you so much !
Amazing instructor
There is a confusion about off delay timer. In my anderstanding ,there are 3 types of off delay timer. 1)- pneumatic timer could used for off delay 2)- True off delay 3)- with signal contact the off delay should always be energised

*YOU DIDN'T TELL HOW TO CALCULATE THE GAIN?*---how tp calculate the gain and how got the value 200? What if the base voltage is same as the collector boltage? Is there a simple way to calculate that in that case?
Thank you for your great question. I get your frustration. You are not alone. I had a similar issue when I first started learning transistor theory. The thing is, the Gain is not calculated, but put into the design of the transistor by the manufacturer. The manufacturers decided what the gain is and then include that information on the datasheet. This gets a bit more complicated, because the gain changes with the collector current. If you look at the date sheet of any transistor here is a link: chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/www.onsemi.com/pdf/datasheet/tip47-d.pdf If you look at the Datasheet, you will see the Gain chart hFE DC Gain Current Gain. The Max Gain is 150 when the collector current is low and the and the minimum gain is 10 when the collector current is at its highest (The highest current is listed as 2 Amps) Knowing the Gain, you can do all the math I demonstrated in the video. I would like to also note that I used a gain of 200 to make the math easier, but it is an uncommon Gain. Typically, smaller Transistor have a lower max gain lie 80- or lower for the max collector current, I hope that helped your frustration.
Thank you for this video with a great explanation. Just in practical situations Beta(saturation) = 10 NOT 200.
Thanks for all de ideas and instructions you give us... better than nobody....nice!!!
Greatly explained, thank you!!!
Sounds like you know what you're talking about, but are extremely muddy and drag out simple concepts with far too much unnecessary tangents. Simple explanation is the connection flips between the NC and NO pin when the relay is energized. That's how you start, and add small details as needed. You lose people by talking all over the place and having a messy drawing. Video could have literally been 2 minutes long, had plenty of detail and been straight to the point.
Is there any timer that on/off every month or biweekly for like few hours?
great explaination with symbol elobrating . thank you sir.
Thanks a lot hunter Biden!
Love the energy.
Lars makes sense of relays, momentary buttons, NO/NC etc for me. Thanks Lars.
DON'T use the term OPEN when describing a conducting diode or transistor. YOU ARE CONFUSING YOUR STUDENTS...Open is a poor choice of words..also the reason the water valve analogy is just confusing to newbies..a closed valve stops water current..an open valve allows full..closed switch..full current..open switch..no current
Thansk for that feedback.
I want a circuit of a pump that runs for 20mins, stop for 2hours and continue the process again using a timer
Thank you Lars Do you know that you are a good teacher, yeah good teacher ;)
Yeah I do 😆 Thanks
Verry interesting 😊

This video may be the best course video that I've ever watched, thank you so much..
Excellent video! I am so thankful for this video! I’m in an industrial electric class and have a new teacher that didn’t receive all relevant resources. There is no curriculum to teach… only labs handed out for us to google answers and wire as per drawings in the lab… sure we are learning, but we need a concise lesson in order to understand them. This video is absolutely great and even having a decent background understanding and familiarity with ladder logic and wiring, I felt overwhelmed with the connections being made in my head watching these videos!!! I will probably watch each one several times!!! Just so short sweet and tied in a bow in only 5-6 minutes! Priceless!! Thank you thank you thank you!!! Please keep it up! You have a gift! For Gods sake sell your videos in different series to small regional trade school/adult education type programs!! Thanks again! I’m sharing your videos with the administrators of my industrial electric class and of course my classmates! I can help drive views of your stuff but only you can really cash in on your gift to teach!!!!!!!
Great explanation
Lars your videos have been super helpful, I hope your're just taking a break and you're doing well!
