I'm an elevator mechanic and work on some of the oldest and coolest relay logic elevator controllers you'll ever see. It takes a long time for most people to wrap their head around a simple relay circuit. Whenever a new guy sees an old bank of 4 elevator controllers with a dispatching controller that has hundreds of relays they are completely blown away. I'll never forget my first time, I thought I would never understand it. Today I can modify and engineer my own new circuits on existing controllers for whatever code updates or new applications and/or operation is required or neeeded. Total respect for those old time engineers.
My warehouse is quite new. A lot of the relays have been replaced by PLCs sending a signal to a contactor. But E-Stop circuits from the push buttons, fire alarm pull station, and fire sprinkler all use a relay to kill power. It's more reliable than a computer.
Clever little tool, but don’t know how I would use it at home or at work. But it’s always good to have in the back of your head for future projects. By the way, I saw the gifts that you sent to Curtis at CCE. I am 57 years old and hope to be like Curtis when I grow up. Of course, you know men never grow up.
Seriously, I cannot excuse the mess, 😱 😂. Though, since this is another great, well thought out, excellent video, much has been forgiven. Much appreciated, for your time. Thank you. Hope you like the joke, starting off in the comment.
Great content, brother. Thank you for taking the time to do this. Maybe you could do a short on how a latch keeps the start powered until it's stopped.
Strangest relay failure I've ever seen was on the estop circuit on a conveyor(estop circuit just controlled power to coil of a relay in control panel). I hit the estop and a few minutes later noticed it was still running(but not being fed. Shut the machine down and called the shop, but when they showed up, the estop circuit was working fine. A short time later it happened again, I opened up the control cabinet and the plastic cover had came unglued from the base, and it's weight was keeping the contacts closed without the coil being powered.
Id like to set up a little test station on my work bench with some variable voltage outputs this is a great fist step like you said simple but useful project
We were building a machine and used relays for communication between a PLC and hydraulic press that used different “languages”. Relays NO contacts wired to the inputs of the other machine. Allowing them to “talk”.
Really enjoy your videos they are very informative
Thank you! There is so much garbage on the internet, I’m just trying to add something useful. lol

That’s awesome!!
Love your video's, keep them coming!
Thanks, will do!
That 8-pin relay base looks just like an octal base from the tubed radios and television sets I work on.
Great video excellent video to visualize how this basic circuit works
Glad you liked it!
Great video Dan Thanks!
DAM DAN☕️👋
YOUR CHANNEL HAS GROWN 👏👏👍
It’s been a journey that’s for sure! Thanks for sticking with me for since the beginning!!

Absolutely!
Definitely looking forward to this video.

brilliant, thank you for spreading ur knowledge w us 👏👏
Very informative!! Like these vids

A relay opens and closes electrical contacts. A solenoid does mechanical work.
Great info! Would like to see how a latched relay works!
