What a fantastic tutorial videos. All you need for learning quickly and easily. Visualizations are great. It simplify the the difficulty and help you to learn more than you expected.
Dear RealPars, you cannot imagine how much these videos help us as amateurs in this field, so thank you guys and I hope you keep going in your amazing fabulous job.
Just took my first job as an Automation Engineer with a regional electrical distributor with a focus on controls and safety. With how smart controls are getting now a days, it’s almost impossible to not know how they integrate with a PLC so these courses you put out are just unbelievably helpful in connecting the dots you otherwise would not be exposed to. Thank you for all the great lessons!
Thanks a million for your feedback! Great job on your new endeavour! We are more than happy to hear that our video courses have been so helpful. If any questions pop up along the way, please do feel free to reach out at any time - we're more than happy to help! Happy learning!
This is on point! The animation and visualization is just fantastic. So fantastic a job of visual animating and explanation, this video can literally be used just about anywhere to explain an Electrical Control Panel. A Big Hug 🤗 to RealPars! I get better at my because of RealPars and many people here all feel the same which says immensely a lot.
Thanks for your comment, Moaaz! At the moment, I have some links to download different versions of STEP7, hopefully, that is helpful to you as well. sie.ag/2eH6GEM sie.ag/2Jt80F0
Your videos are very explanatory and take many doubts, you could by subtitles in Portuguese, because I have difficulties with English, I already thank you
Good video, I would only suggest you don''t run the Ethernet cabling right next to the incoming 480V. It's good practice to keep your network cabling out of wireway and away from AC voltages. Lastly, AC should ideally come in from the top and work it's way down.
Thank you for the comments. Correct, long runs of AC voltage-carrying cables parallel to low-voltage DC wiring (like Ethernet cables) can cause a problem. It is not likely you would have a problem with the short run in the panel shown, but to be safe, yes, separate voltage levels in separate trays/panduits. Normally, AC voltages are highest in the feed cables, so working downward usually keeps the highest voltages away from hands and fingers. Thank you for the input!
This is the best illustration of Electric Control Panel I have ever seen. Thank you very much RealPars team! You are awesome and keep it up! I wonder if you had any institute or training center, I would be the first to take admission there.

Similarly, an electrical control panel is a metal box which contains important electrical devices that control and monitor a mechanical process electrically. ... An electrical control panel enclosure can have multiple sections
Dear RealPars, these videos are wonderful, they're a perfect initial guide, thanks a lot. I wonder if you know about a standard or normative to design a control/electric panel (component positioning, general considerations, and so on).
Thank you for your kind comment! We're very happy to hear that! Regarding your question, I will happily forward that to our course developers as a topic suggestion. Hopefully, we can create a video course on that in the near future. Happy learning!

Thank you for doing these videos. I recently started working for an engineering firm in administration. Your videos are invaluable in establishing a baseline level of knowledge.
I liked this video! This is a very good basic control panel. Good introduction for people who are not into the field. For most viewers, FYI, it could get really complicated and you would have other Panels that do not have PLC's in them but have other PCB boards and other controls such as electromechanical relays, control valves, manifolds, etc, they are called sub panels. Other Sub-panels can have shunts and Servo-drives in them and so forth. Again this video is EXCELLENT intro. Lots more to learn like connectors, and so on.
Thanks for reply. I am still confused about it. As I know, '2 wire connection' use 24VDC and two wires for both power and signal and '3 & 4 wire connection' use additional wire for external power like 120VAC. I can't match 6:04 '3 wire connection' with either '2, 3 or 4 wire connection'. It does not use external power but use 3 wires? If you explain more, it would be very helpful. Sorry for asking again.
There are also 3-wire DC devices, like transistor-based (solid state) proximity switches. The three connections are +24VDC, signal, and ground. We have a blog entry that explains this concept (realpars.com/discrete-sensors-part-2/).
I noticed that the outputs were only 2 wire.. one connected to the negative and the other connected to the output terminal.. is that because internally in the PLC the output is connected to the positive when switched to complete the circuit?
Yes, internally a contact closes when the output is energized. This completes the circuit to the output device. The PLC output can be a relay type output or a solid-state switch.
Good video! Well done, only thing I would recommend is showing the dirty and clean wire ways. Running a low level signal in parallel to 480 not so gooda.
Our subcontractor delivered us a very sub-par control cabinet. Now I, a software engineer, am rebuilding significant parts of it to improve organization and maintainability. Also it just didn’t work because of the software, which is why I’m doing this. Thank you for all your videos I can use to make sure the replacement is clean and organized
It's been a great video... Thanks for this.. But I believe you miss to include grounding bars , instrument Earth bar and electrical ground bar for earthing / grounding requirements. Nevertheless, Keep up the good work 👍
Thanks for concise infographic, Just wondering what component will protect the system against current overload (amps)? Also many control cabinets consist of a UPS & Fan to cool down the Drives/plc/UPC inside the cabinet,
Fuses or circuit breakers are used to protect components in a panel from over-current conditions. Large loads, such as motor starters, transformers, and VFD's, have fuse protection on the incoming branch circuits, and individual loads (outputs) are usually protected by fuses or circuit breakers. Local electrical codes dictate, in many instances, what device types and rated sizes are appropriate in each case. Whenever a panel is designed, the environment it is being placed in should be evaluated, so that the proper cooling can be installed, if required. Most panels with motor starters or VFDs will at least have a fan for cooling purposes, just to remove excess heat generated by those components. Some panels in very hot environments may require air conditioners or other cooling devices (vortex coolers). It is much easier to design these in during fabrication than retrofitting after installation. UPS units are most often just used to keep controllers, like PLC's and I/O cards alive when a power outage occurs, so that the process can be monitored.
great 'phenomenal 'amazing 'wonderful 'helpful 'incredible simply the best illustration control panel so far on RU-vid period I'll be very grateful your honor if u do one more video on DCS and slightly I have some points also on PLC thank u
Sir, these video series are incredible effective things to learn from scratch as a mechanical engineer. Amazingg explanation of everything, thank you so much.
Thanks for great video. I have a question. At 6:04, three wires come from field to control panel. Isn't typical wiring is two wire and two wires connect to IO module?
The video shows L1, L2 and Gnd for the power. The numbers of wires depends on the panel power supply voltage, number of phases, etc. The I/O shown has a single cable that is routed to the panel, where the individual wires, either 2, 3, or 4 wires are connected inside the panel. Typically, I/O cards have two connections, signal and ground (common). Additional wires may be required for power.
I’ll start an account management job in a couple of weeks for a control panel manufacturing company. This helped me get some knowledge before showing up day one, thank you!
Thank you, Guilherme! I am actually not sure what software we use for our graphics as this is done by our Graphic and Animation department. Sorry about that!
Best video in your channel and all automation channels on RU-vid. All your videos are amazingly helpful and educative. Thank you for the time and effort you put to help us 🙏.
I work in a distribution centre. Im not on the maintenance team but im interested in how the machines work. So there is a tote conveyor that collects products when it passes through an a frame picking machine and also gets loaded when it passes some robots. The totes dump their products at packing stations. After the packing stations the products then get put onto a shipping conveyor that has bar code readers and proximity switches which tell the sorting conveyors which shipping container to dump the products into. Its amazes me how man can make such machines. I also understand most of the stuff shown in your video. Thanks.
Hi Mike, Thanks for sharing that with us, it surely is fascinating! Please let us know if you have any questions. We are more than happy to help! Happy learning!
i already signed up with your subscription but i couldnt find these videos on your site and also i cant get a communication with your any guys for any questions.
Hi Ali, Thanks for your comment, and my apologies for any confusion. The free RU-vid videos are not in our course library, due to the fact that our course library is filled with exclusive video courses - only accessible for paid subscribers. It wouldn't be fair to pay for a subscription that includes video courses that you can also watch for free. Additionally, our free videos on RU-vid do not follow a specific start to finish structure. Whereas our course library is specifically designed in a way where it provides all the tools needed for beginners to evolve into an advanced level through our hands-on courses. I am sorry to hear that, we have a 24-48 hour response policy on all our support channels. You can reach us at hello@realpars.com or support@realpars.com. I hope this answers your question sufficiently. If you have any other questions or would like any further assistance, feel free to reach back out.
Excellent video sir! I found this channel yesterday and in just one day has become my favorite engineering channel. I would like to ask a question. The power section and the control section can be separated and put into two separated enclosures? And how the components would be arranged if they were in a one door enclosure? Thank you su much
Panel segmentation by voltage is very common. The safest way to arrange components is to place all 200/400 VAC and above components into one panel, 110/120 VAC components into another panel, and 48 VDC and below into a separate panel. That way, 24VDC components can be accessed when "live" with minimal PPE through an open panel door. With the AC voltages, higher levels of PPE and access restrictions are usually required by code and/or local standards. Other ways of doing this would be to locate all AC components on one side of a dual-door panel and low-voltage DC components on the other side. A third way is to have a single-door panel with a plexiglass guard over AC components so that the "live" contacts are not accessible with fingers.
Good question! Many times the incoming power to a panel is 480VAC which is used to drive motors , heaters, and other similar equipment. This voltage is too high to be practical for control circuits, so a transformer would be use to step down 480VAC to 120VAC, which can be used for control circuits, like relays and motor starter coils. Finally, a 24VDC power supply can be used to convert 120VAC to 24VDC for PLC I/O cards, interposing relays, and other control devices.
