Basic Ladder Logic (Full Lecture)
Basic Ladder Logic (Full Lecture)
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)

This is excellent. Thank you very much
Excellent tutorial. Sincerely appreciated!
NEATLY EXPLAINED. 🙂
thoda aaram t bol le k paani tode ga.
thanx a lot for awesome concepts
good points mentioned in the video.Enjoyed a lot.
Nice explanation, but in the example at 25:53 where you added the stop push button; be represented with the push button on the bottom of the ladders rung to illustrate that you are actually pushing rather than pulling? Judging by only a few moments later it appears the stop button you created penetrated the rung to stop operation. Maybe it doesn't matter, just an observation, I know breakers in simplified form can be shown as a stop partition that is on top of the rung, but those are also generally on the right side of the rung too, like the relay.
I don't understand at all from the start what are you saying. What are you describing ??? Sorry 🙁
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.
The point you made at 10:15 had me laughing out loud! I can just imagine the lab-instructor barking at the confused student to get down and give him 20 in full metal jacket – style!
I think the plc program at the end is wrong. I1 and I2 and LS should be NC.
Nice one. Keep it up
i don't like American accent its sometimes rude and earache
Good stuff…nice review
Very helpful thank you!
Thanks
excellent lecture…thank you very much…
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!
This was great 🙂
Please tell me why the overload is located on the neutral. This can only make things more confusing. (ground side switching) if the overload was located just to the left of the coil… all circuits would be positive switched and much more intuitive.
amazing!
I just wanted to say Thank you
Thanks Jim. 👍🏻
Thanks a lot for sharing this vid. It is amazing!!!
Great Video and to the point; Thanks.
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.
Got the basic logic after this explanation., thank you
so wait is a holding circuit what you call a latching circuit here in Canada? are they the same thing ?
Wow excellent I need to study this wish you was my mentor trying to get a job as a controls tech
Excellent video! Thanks for making this information available publicly.
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.
Finally someone who can break down schematic diagrams to the basics and explain with clarity. Youre amazing!
AWESOME Tutorial
Best lecture ever!
How do you show a maintained button vs a normal button? Is it that the button is above or below the line, or is it the semi circle you drew over the button? Thanks!
Thank you for this lesson
