=============================
We get many questions about the basics of electrical control panels, such as what devices and equipment we typically use, how the devices are wired, how to keep the control panel and the cabinet within a normal temperature range and so on.
To answer some of these questions, we decided to go to one of our partner's workshop and shoot a practical video reviewing an actual electrical control panel, for you to see what the basic components of a control panel are, how they are wired, the function of a thermostat and so on.
This is a 2-door control panel that is used for a system that turns wastewater into clean water.
Here is a summary of what you will learn after watching this video:
• We name control panels based on the number of doors that they have. For example, one-door, two-door or three-door control panel enclosures depending on how big of a panel you have. The more equipment and devices you have, the larger the control cabinet you will need.
• We usually have some switches that are connected to the PLC inputs and outputs. For example, one of these switches could be ’Mute Buzzer’. This is the button that you use and press when there is an active alarm on the system.
• You use the big red Emergency Shutdown push button or the E-Stop as it’s often called to shut down the whole system when there is an emergency.
•A PLC is a unit that usually includes a CPU and a few input and output cards.
•What is the difference between a “Wire” and a “Cable”? A wire is a single conductor but a “cable” is a group of wires that are covered in a jacket.
•You need to label each wire to be able to make the uniquely identifiable, which helps with troubleshooting if there is an issue.
• Sometimes we have two power supplies in this control panel with different output voltage. That is simply because we have some devices in the control panel that works with 24 volt DC and some other devices that work with 12 Volt DC.
• The reason that in this control panel the 24 Volt power supply is bigger in size is simply that here we have more devices that need 24 VDC to be turned on.
• We usually size the power supplies based on the amount of current output that we need. For example, we have power supplies with 1 Amp, 3 Amp, 5 Amp, 10 Amp, and 20 Amp output current. The more devices we have, the more current we need and the bigger the power supply gets.

A video by making an exhausted review of each electrical component teaching how they work and how to troubleshoot can make a boom on this channel, love realpars
We love you back! :)

Omg I have wondered for YEARS what this stuff was and always wanted to find out. This channel is a gold mine and these PLC-oriented videos are incredibly resourceful! Thank you so much for making these videos.
Hi Nick,
Many thanks for your kind compliment! We are always extremely happy to hear such positive feedback! If you ever have any questions, feel free to reach out to us. Happy learning!
As usual, the best time-investing in learning industrial automation comes from you RealPars. Thank you and Pro Controls for taking the time for bringing to us new valuable and informative material. I'll be expecting more.
You are very welcome, Melquiades! Thanks for sharing your positive feedback with us! We appreciate that.
you probably dont give a damn but does any of you know a tool to log back into an Instagram account?
I was stupid forgot my account password. I love any tricks you can give me
I am currently being trained in PLC automation for the process industry since my graduation, these videos really help me a lot! This channel has made automation so much easier to interpret.
That's amazing to hear, Urvashi! Thank you for sharing.
I can help you … working for Emerson
Your email please...?
Arcturus
Videos like this can really help me when it comes time for me to take my practical test at work. I’d love to see more videos like this! Thanks for all your videos
Hi Lawrence,
Great to hear that our course videos are so helpful! Keep up the good work and feel free to reach out if you have any questions along the way!
Very comprehensive and detailed video, honestly one of the best Channels for Electrical, Instrumentation, and automation!!
We are so stoked to hear this, Thagmal! Let us know of any questions!
Excellent video ! I did custom work of this type for 27 years. These videos could have saved me so much time training new employees. Great job on the wiring too. Thank you.
Thanks a lot for your kind comment, Tim! We appreciate such feedback!
Great! I have been watching RealPars videos for a long time but this video is quite different than the previous ones which were quite a bit theoritical. And very special thanks also to Pro-Controls for collaborating to take this video of practical, real world example which is much more useful compared to standard, nondetailed, theoritical ones. I appreciate the way of teaching in detail every steps in the panel. I love this channel.
Thanks a million for your positive feedback! We truly appreciate that.
After years out of the business I'm using these videos as a refresher. They are well done and informative. Thank you for making these with such professional quality.
Hi Rick,
Thanks a lot for your kind compliment! We are always extremely happy to hear such positive feedback! If you ever have any questions, feel free to reach out to us.
Happy learning!
very helpful to understand the practical situations.....with such a simple explanation of the panel components
Great to hear that, Akshit! That is the goal were aiming for!
Happy learning!
Great and simpler explanation.. Appreciate the effort..
Thanks for your support!
Elaboration of every small information & technicality makes this video super informative.
Great to hear that! Thank you!
Thanks alot, it make electronic be simple
Very well explained with all the details.
Please don't learn people to wire a emergency stop function direct to a plc. Never trust a program to handel your safety. Always wire a safety controller, this checks for wire continuety. So wen a wire got lose your emergency conyoller shuts down. A few examples PILZ pnoz , twinsafe from beckhoff. You can wire a feedback signal from your safety controller directly to your plc
In the panel shown, there are many wiring connections between the devices. The ones connected to the PLC are the only ones that we have explained in any detail in this quick overview. Typically, one E-Stop contact is brought into the PLC for indication, and a second contact is used to interlock power supplies, outputs, and device circuits.
Thank you very much for giving this idea we should not trust in program we should not consistrat in function we should consistrat in our study good luck for the education
It was so much easier when computers weren't running EVERYTHING. I'm for automation, but my gosh when the Drawings have been made into trees and programmer is hiding somewhere I'm the Bahamas my hair turns Grey each second trying to......
Thank you for the helpful video. I love to watch your videos. You did a very good effort. What I would like to see in the next videos is what rules should be followed in shielding, earthing and grounding the control panel, VFDs, PLC and sensors.
Thanks again. you rock.
Hi Ahmed,
Thanks for your comment and your suggestion. I will pass this on to our course developers!

Just what I needed. Thanks 😊
Great to hear that, Ben! Happy learning.
I would love to see in-depth wiring of 3-phase induction motors (Star-Delta). Also modulating motor speed (VFD) using different protocols (4-20mA,HART, Profibus, Profinet) side-by-side will be very good as well.

Thank you very much Sir
You're very welcome, Asad!
Thank you so much !
You're very welcome!
Love you... you're doing very good job...
Thank you so much!
Absolutely love RealPars... Can you please upload a video on process control for bread tunnel ovens? Like those which use RTD a temp sensor and modutrols as actuators for increasing or decreasing the flow and pressure of combustion air? Such air coming within a pipe, thanks to the venturi principle, entrains and mix with a volume of gas. The air/gas mixture is then finally burned at a ribbon to increase heat output depending on temp SP. Go ahead!!!!
Hey Alejandro!
Thanks for your comment and your suggestion. I will pass this on to our course developers!
