Control Relays (Full lecture)

In this lesson we'll introduce the control relay, an electromechanical device that forms the principal logical element of an electrically controlled system. Relays can perform numerous functions by selectively energizing or deenergizing other elements within the system or between two separate systems at the appropriate moments to coordinate and sequence activity.

I've watched this lecture a thousand times. It's my go-to for explaining the basic function of a Relay to my technicians because even they sometimes make dumb mistakes. Thank you, Jim.

[ansirodesetta]

As a mechanical/electrical technician who works with ABB automation, this was informative and a great study.Thank you Jim

I really can not thank you enough for your very informative & detailed lecture,
Thank you a million times

[abiom]

The best plc video education ever. Thanks Jim

First, what you do to all students, electrician, and engineers has a significant impact to their lives, knowledge and experience. And I personally appreciated. Second, Can you please let me know if you have any books out there authored by Mr Pytle.

The IEC numbering explanation is fantastically useful!

[briancarson]

Thank you for making this information available and presenting it in an easy to understand way, very appreciated, take care!

[frederickchikwe]

Jim, you are the best of bests. Do one on Safety Control Circuits as soon as possible. Thanks a million.

Hi Mr Pytel,
For several months after first working with control relays I had been referring to this video to refresh my understanding when work with relays was required. Through repeated work experience and repeated exposure to this video, I was able to move from nebulous understanding to a solid understanding of control relays. In my work I am also regularly exposed to safety relays. Saddly there is no online resource that I have been able to find that explains them in any detail. I know you are very busy, but would you consider doing a lecture on safety relays and safety switches at some point in the future?
Thanks for all your help,
John

Hello my friend bless you'll for sharing keep up the great work GOD t

[yirgaabay]

what a lecture for all your effort you made to bring us this( other) outstanding videos....

[engr.amitbanerjee]

Awesome video to be very clear about control relays...
thanks a lot...

[jamesquiroz]

Thank you, now I can understand much better electrical-mechanical relays!!

[jejefred]

Nice presentation sir. You are indeed wonderful.

7:34 ... Is the common terminal second digit for the Single Pole Double Throw ever "3" instead of "1"?
Would both of the double throws need to be normally open?
