- In this lesson we'll take an introductory look at ladder logic diagrams, the principle means electrically controlled systems use to document and convey not only connection of individual devices making up the system but also the function of that system. Additionally, this lecture includes coverage of a handy configuration called a holding circuit. (Full lecture)

Excellent lecture. I've not been able to fully grasp ladder logic for a long time--especially holding circuits, but you have explained it thoroughly and in an extremely well laid out and organized manner. Your teaching style is impeccable, thank you.
Agreed
This is sad and funny to me as a professional technician. I have paid for courses like this in the past, and this is vastly superior. These types of circuits are fundamental, and clear explanations really help comprehension. I am looking forward to moving through your series as I move towards the PLC series.
I don’t understand why more people don’t take advantage of videos like these. I’m studying for a test for a promotion and this video has better information than the electrical schooling I PAID for.
Glad you're making use of this material. Tell your friends!
Thank you so much I can't believe your 4 year old video is still helping people including me thanks alot you explain very very well keep it up !
Excellent job Jim. Thanks so much for sharing. I'm a self learner. Your tutorial kept me motivated and made my learning process easy going.
This has just become my current module topic and its all new to me. You have explained this very well and it all makes sense. Thank you !
Excellent tutorial. Sincerely appreciated!
Thank you, Jim. You are an amazing teacher.
Finished school and started a job in a steel mill.. overwhelming.. revisiting the basics is helping me..
Excellent video! Thanks for making this information available publicly.
Awesome videos you have. I finally understand ladder logic and complex circuits are made way, WAY easier now. Thank you!!
As a person with knowledge in the subject I can say with confidence that the way Jim approaches the subject is the best that I ever seen , this channel is treasure of resources.
Thank you for this video. I am a Ranken Technical graduate from St Louis, Missouri. Been out of school for 5 years & most been doing apartment & hotel maintenance. Not much PLC work since my first year out of school. This definitely helped me brush up & get more confident as I prepare to take this quiz for a new job working in an industrial facility. Didn't even have to get out my notes from school, this video helped all the information in the back of my head rush to the front if my head...
All I can say... Thanks so much, too much knowledge, be blessed
brilliant lecture just in old school jim pytel style. Thank you so much for such valuable contents. You're definitely making this world a even better place.
you cover more information in a concise and helpful manner than many other people. I was a little confused when you mentioned the run using manual mode. Thank you for teaching useful concepts.
THANK YOU, FOR THIS VERY WELL ILLUSTRATED, AND EXPLAINED TUTORIAL, ON BASIC "LADDER LOGIC" DIAGRAMS, AND "START/STOP/HOLD/E-STOP" CONTROLS!
Jim you’re the man ! Excellent Tutorial 👌🏽
Thanks for explaining this. While I am used to reading standard standard electrical schemactics, I had been throughly confused by this weird schemactic that came with a piece of used equipment I had purchased. Now I know what it was and will better understand how to interpret one in the future.
You are good! i was kindof frustrated with the general basics videos that i found about ladder logics and i was wondering why they didn't talk about the actual working ofthe keys, switches and the logic behind it!
This has been Extremely Helpful and i'd recommend it to my friends for sure.
This is a wonderful lecture. I didn't understand how it works but I can draw the ladder diagram now. Wow, I will be one of big fans of you. Thanks.
This is absolutely amazing tutorial. I have just graduated from college with an Electrical Engineering degree. I want to make my career in Automation Industry. Thanks for the help.
Solid video, just simply explained and goes in order perfectly
you are so right, the first time i tried to dive right in and understand this it was very frustrating but i put my time in and now its like, yeah this is definitely making perfect sense thank you for making such a good and thorough teaching channel and you cover so very much for someone like myself who wants to jump from being a welder to working with electricity
Best lecture ever!
Finally someone who can break down schematic diagrams to the basics and explain with clarity. Youre amazing!
That's a lecture, great. Thanks
Nice one. Keep it up
This is excellent. Thank you very much
This seemed so complex initially but it made sense to me, thanks Jim!
Got the basic logic after this explanation., thank you
Extremely well explained!
Fantastic, thank you for sharing all of this information.
I'm 2 weeks into an introductory Industrial Maintenance Tech course and was having some trouble with the electrical Ladder logic but after viewing this video, I finally feel more comfortable with this. Thanks for putting this out there. It really helps. All I can say is thank god for rewind...
Very nice! Glad you're making use of this material. Please tell your instructors and fellow students know about this resource and make sure to check out the complete motor control playlist at: th-cam.com/video/LM8U9FCMDx0/w-d-xo.html
Thanks a lot for sharing this vid. It is amazing!!!
Wow awesome video! I need few more times to watch.
An excellent lecture. Well organized and easy to follow. Many thanks for your the time to prepare this video. I am a chemical engineer but need some basic knowledge of wiring diagrams. This is the best material I have found on the internet. Greetings from Poland.
Nie ma za co!
Thank you for this lesson
Thanks Jim, you explained this in a way more easier way than my teacher has!
Very nice, please tell your classmates about this resource.
Very helpful thank you!
Thank you for this. I learned quite a bit.
ohhh...im newbie to this channel...i like the way it is to refresh my college days.. but the way you discuss about diagram i noticed you fotgot to label to im losing fucos on where im am in the part of discussion but over all its nice...thanks..
Great Video and to the point; Thanks.
So glad I found this. My instructor for electromechanical control systems just reads off of power points. He should recommend your video. It's fantastic. Easy to follow and great explanations. Btw, you just helped me with a very similar hw that I couldn't quite figure out. It has to do with 2 solenoids and a light coming on to show which one is active. I think my circuit will work now. I even added the e-stop. 10 million thank yous!!! Subscribed. :)
Very nice! Glad you're making use of this material. Please tell your classmates about these free resources. Here's the complete motor control playlist: th-cam.com/play/PLdnqjKaksr8qRPCFkU2Q8XQe0bfo99rs6.html
Thank you for taking the pain to do this beautiful lecture going from the simple circuit to the complex ones. You are speaking too fast though so I had to slow the video in order to keep up. Thank you so much.
Great work, thank you!
Great job perfect teaching
I just wanted to say Thank you
Very clear and well explained.
Being a few weeks out from completing my Industrial Maintenance Degree; I gotta say I enjoyed the tutorial and clearly understood everything you was explaining. As you mentioned it is very overwhelming in the beginning but don’t panic, allow your brain to process everything for a couple weeks, if it were easy everyone would be doing it.
If it were easy it'd be called snowboarding!
Good stuff...nice review
Great job. I'm an electrician apprentice 4 weeks in. Totally confused every day. Thanks for making it clear.
very nice! Glad you’re making use this material. Please let other individuals enrolled in the apprentice program know about these resources!
Excellent explanation thank you 🙏
Wow, you are an excellent teacher sir.
Beautifully explained
NEATLY EXPLAINED. :-)
Great explanation
excellent lecture...thank you very much...
Extremely helpful video!
AWESOME Tutorial
Brilliant. Many thanks.
Thanks Jim. 👍🏻
back again! Now I'm out of the apprenticeship and taking a continuing ed class. Yet another instructor sending us here.
Im glad for it!
Welcome back! Working on some new pneumatics material right now then returning to the motors and generators playlist.
very nice explanation, thank you!
You're such an excellent man
NO OTHER WORD THAN AWESOME, THANKS
Hi! I am from Brazil, Rio de Janeiro ...i liked the song you start your video!!!!!
good points mentioned in the video.Enjoyed a lot.
That intro song 🔥🔥
This whole video 🔥🔥🔥
I have seen a load only device in a ladder logic diagram, usually as an indication that the panel is powered, or as a alteration timer in the diagram, these are exceptions to the rule.
Fantastic lecture
I had to pause and say Thank you Sir!
Great video thank you!
Thank you for the great video. I am sharing with my Manufacturing Controls course.
Very nice! Glad you're making use of this material. Give me a shout at my cgcc address and I can send you some more resources for your class.
Google must introduce a feature where we can thank you again and again with a thumbs up every time we feel gratitude.
One always has the option of writing "Thank you!" on the side of a G5 Optix XR bow sight with floating hybrid pin and sending it to me!
Nice job keeping it real👍
Very well explained thank you very much
awesome lecture !!!
Excellent lecture. Keep it up!
Thanks! Please tell your friends these free resources exist.
Jim this is super as others are
amazing!
you are great teacher. may the lor
d continue to enrich your knowledge
Outstanding lecture! The hard wired e-stop circuit shown here is the most straightforward way to stop a machine. Also NFPA-79 requires that e-stops be normally closed contacts, and cannot be integrated through a PLC. However, a safety relay or safety PLC (like a PILZ) may be used since they are designed for that purpose. I have seen machines that use normally open contacts for the e-stop and use the regular PLC to stop the machine without cutting power to the control transformer. These will not pass an electrical inspection. Thank you for demonstrating the correct way to control!
True dat! If there's one thing I learned from watching the Terminator is to never trust a machine. Check out the "PLC Interface" lecture at: th-cam.com/video/G4uo0Sm0uMo/w-d-xo.html where I expound upon the necessity of a fail safe means of killing a machine dead.
Jim amazing explanation :)
Dude . You rock star
Amazing!!!
This was great :)
Outstanding
Great lectures . Superb . Thankyou
Don't give me too much credit. I just turn the mike on, click record, and make it up as I go along. Just kidding. Thanks for the kind words. Lots of work goes into this material and I'm glad you're make use of it.
love your videos. personally, its really hard to follow when there is a mistake in the animation (like NO and NC contacts) and i have to read a correction box and keep imagining how its supposed to look like AND follow the words of the lecture. thats just me though. just wanted to give some feedback to help improve the channel because i like your content and how you teach
and also the part with the limit switch was a little hard to follow in terms how how it was being used
You are awesome!!
Excellent presentation. One comment is that at 12:05 its mentioned that there should not be an "output only:, I've often seen an indicating light just tied across as a "Control Power Available" indicator,
At first I thought this was a dumb video, man was I wrong! Super good job!
Thank you!!!!!
Thank you sir
You are the best
Your the man thank you!
Can you make some videos on timers ,counters and other type of options offered on allen Bradley or plc .
Stay in touch. I’d like to cover these topics and more in later lectures.
Helpful
Lamp "C" is always on, alright? Just let it drain power continuously until it 🔥 burns out 😂😂😂. It's Title 24 compliant, don't worry. 😉😁 Seriously though, really LOVED the video, TY.
If you can understand this, troubleshooting will come easy to you.... I took a course similar to this for industrial electrical services and since then, if you give me the diagram and schematics I can troubleshoot with the best
Very good
