Relay Card Wiring का सही तरीका⚡ Relay Card Wiring में ये गलती मत करना! @ElectricalTechnician

If you want to learn PLC wiring, then this First, you need to learn the wiring of this device. This device is called a relay card. In the relay card, the terminal provided It's his name written here. It's a very different way; which one is common, which one is NO, which one is NC How will we identify this? Let's understand this entire detail through this video. Friends, first of all, understand this: the relay card here The relay card is also similar to this type of glass relay. As you know, a glass relay is one that contains a is a coil, and to operate this coil, this coil's We will have to provide power at the place where the terminal is located. And in this relay, we get a common NO NC here, which is You can turn any circuit on or off using it. Everything you have here in this reel card will be available to you. The only difference here is that it has only a particular relay. And here, a total of four different relays have been installed. You might also come across eight reels in some of them in the same manner. So if your relay card has only four relays installed So, understand it's the four-channel reel card. And if this type of relay card has a total of 8 relays installed So that will be our 8-channel relay card. Now understand here that our relay is the one In order to operate this relay, we will need to supply it with power. This first relay — in order to activate this relay, we need power. The first and second terminals must be provided. So, the number here tells us this Which relay will turn on when power is applied to which terminal? As for the terminal of one number, which is this The first relay will operate upon applying power. Apply power at the second position; apply power at the third relay position. When power is supplied to the third relay and then to the fourth relay, the fourth relay will turn on. Now we need to understand here what we have at this place We will connect AC power supply or DC power supply And what should the voltage of our power supply be? To understand this thing, you need to look at the relay above You will have to read the details written there right now. But you will see here on top of this relay, 24 volt DC It is written, perhaps it does not appear proper to you here I mean, to turn on this relay, here we Connect a 24-volt DC power supply. Now, the relay will turn off from here. But the common NO NC of this relay You will see the common NO NC here below on the side. 1 This means that this is the first relay's contact. 2 means second relay 3 means third And 4 refers to the fourth relay. Now, regarding the relay here, the contacts that it has, You will notice that the name is written in different ways here. This COP is written in this type; you will never see any relay like this. It should say "Common NO NC," but here it says "COP." Could you please tell me in the comment what C stands for? I mean, here, the pole of our relay, this relay's pole, Where we give input power, here you say common, which is there. It is denoted by P, where P stands for pole. After that, to understand NO, NC, understand what C has become. NC, and O now mean NO; understand one thing here. So, O, what on earth has happened? In NO and NC, the last one is C, so C means NC. Now, regarding the wiring of this relay card here We also have to install a jumper here at this location. As you will notice here, a small jumper is provided. So, what is this jumper, and how do you use it? We understand this as the complete wiring. At this moment, if I need to keep this relay turned on, I'll have to provide power to it in order to keep it running. And to provide power supply, I will use an SMPS here. In addition, I have installed a circuit breaker here. So that I can keep the power supply turned on here via this method Now I will connect a single-phase supply to this MCB here. And at the same time, I provide neutral supply here. Now, at the place of the output terminal of this MCB's phase, connect a wire. We will connect it, and from this wire, connect to the point marked L in this SMPS. The phase supply that is there, we will provide it. Now, regarding the neutral supply of MCB, that neutral supply Connect this wire by linking it with a wire. We will provide the neutral supply for our SMPS. Friends, before moving forward, I would like to inform you that if you If you want to acquire electrical knowledge through a book As you can see here in this book, here it is reverse forward The starter made was also a star delta type reverse one. If you want to study the diagram plus the theory of the force starter You want to understand the complete working; you want to understand the connection diagram. Moreover, your conventional star delta starter that exists How do you wire the power wiring and control wiring? How is interlocking done? It has been explained to you through a picture wire diagram. It is also explained through a circuit diagram, How do you control the reverse forward starter of your system in this manner? How to connect a float switch? How to install a selector switch for auto/manual operation? If you want to acquire all this knowledge So through this book, you can take it So if you want to buy the PDF of this book So, you'll get the PDF of this book for just 98 rupees. And if you want the book delivered to your home, then 600 Your book will reach your home in rupees. If you want to buy it, then the video I'm sending the link in the description, go there Please provide it or if you need a PDF So directly you can reach me on this WhatsApp number Please send a message by typing QR. So for this, I'm here connecting the positive power of this SMPS Either the positive power supply or the negative power supply, whichever you prefer I can use it, which I want to use for controlling Right now, I'm here positive I'll use the power supply that's available. For this, the positive terminal of the SMPS I'll just connect a wire there. And the other end of this wire will go inside our push button. And in the push button, you need to use NO here Because we want to turn it on by pressing it. So, the NO push button that is, I am I will provide the incoming power supply here. Now, by pressing this second push button, I can activate the second relay. I want to proceed, so I'm pressing the first push button that I have incoming I have provided power; loop one wire from the same spot and push it second. I will also provide the incoming power supply here for the button. We will bring out one wire from the output of the first push button. Should we connect this wire to the positive terminal or the negative terminal? Look, right now the power we have for controlling Used the positive one The wire here will receive the positive power supply. So, we need to connect this wire to the positive terminal. Now, in the same manner, the second push button It's output; we'll connect a wire with it. And the other strand of this wire, bring it along and connect it to the second relay. We will connect this to the terminal that has the plus sign. Now, if you want to turn on the remaining relays as well, then You can provide the positive power supply in this manner. Now, in order to operate these two relays, we need to A negative power supply will also be required. So for the negative power supply, the SMPS for the negative is a terminal; with that terminal, we connect a wire We will connect it now; take the other end of this wire. Connect to the negative wire terminal. So I'm here with the negative power supply, which is the power I connect this wire to the supply. Now here's a question for you I have supplied the positive and negative power to this relay. so that the relay will operate Now, the remaining relays—should I also include these relays here? Looping wire on the terminal They require a negative power supply. Please tell us in the comments What will be its answer? No, why would you look here for something like this small one? A jumper is connected; this jumper, through which we are connected here The positive terminal can be shorted or the negative one. You can shorten the terminal, depending on whom you're referring to. If you want it shortened, go ahead and shorten it that a positive power supply is here Provide the same positive power supply Let's go to the second one and then the third one. I went to the fourth one, meaning after providing a positive power supply, the rest If you want to go everywhere, here's what you need to do — take a look here jumper that is You will see what is on the first side; it says "positive," so the first one What will happen if it's positive? The first positive one, which is in this case, we have A jumper will have to be connected, as you will see here, connect the jumper It has happened like this, so we will remove this jumper from here. We'll attach the one labeled "type" to the first terminal. So here, the first relay has two jumpers. Positive ones and negative ones will be available So what we need to do is shorten the one with the negative second. Similarly, you need two jumpers for the second relay. One positive and one negative So, you need to wear a jumper on the negative side. In the same way, also the third and fourth ones It's attached in the third one, and in the fourth one, both are open here. Then we'll attach it to the one we want to shorten. So I've placed it here. Now, if I take this one If I turn on the MCB, you'll see that here we have our The LED on the SMPS has lit up, which means that Output power generation has already started. We had connected the green push button to the first relay. So if I press this push button, then You will see that the first relay has turned on here. The indicator light is here, and it is glowing. It stopped because we decided to let it go. No holding circuit is being built here now, second one Push button; press it to indicate the second relay The light is glowing, which means here we have Both connections are proper. When the first push button is pressed, the first relay will turn on. When the second push button is pressed, the second relay will turn on here. What do we need to turn on or off from this relay? Yes, according to him, the common NO NC of this relay is Yes, we can use this at the current time. I want to use the tower light here But I want to turn it on and off through this relay card. So if we need to connect this, what should we do here? The tower light is here. The red light on this tower light is this light. The wire that you need will be available here in red color. You need to bring the wire and take it to this relay, whichever one it is, or otherwise If you need to connect to the NC, then the NO of this relay Now, this yellow light—this light needs to be turned on. In this tower light, there will be a yellow one, that one. You need to connect it here with NO. Now, regarding this PE-terminal, we need input Power means providing a common power supply. Which is the positive power supply of SMPS, that needs to be provided. You can connect a DC power supply to this relay card. You can connect, so you can definitely connect the DC. If you need to connect the AC, you can connect it. It depends on which device you want to turn on or off through it. Does that device operate on AC power supply or on DC? I'm currently using the DC light. Therefore, I am here The positive power supply of the SMPS But I'll connect a wire and bring that wire here I'll connect it with the PE terminal, but The common point of this relay also has positive for me. The power supply needs to be provided, so it should be done on this PE wire terminal. I'll connect another wire to loop the wire. And the other strand of this wire, which is We will connect it with this P. That is, we need to loop through all the P terminals among themselves. Now, regarding this tower light, the negative wire of this tower light is We need to connect this wire to the negative power supply. So, for this, the negative terminal of the SMPS I'll connect it here with this terminal. So,(extremely) our wiring for this relay card is now fully complete. Now, if I turn on the MCB, turn it on After that, our SMPS turned on first. After that, if I press the push button here, this light turns on. And at the same time, you'll see here The red light is blinking. This is our flasher-type light. Meaning, it will be on, off, on, off. So it's turning on and off. How long will it stay on/off as long as this relay is on? As soon as I release this push button will be turned off, and due to this Light is also our captive. Same way, our second relay which is Press the second push button to activate this relay. And after pressing the second push button, the light here has lit up. Meaning, the second relay has already occurred, and this relay's The second light turned on from NO contact. If I use the NC contact of the relay here As here, I disconnect the wire of the first light from here. And the NC contact, which is the NC contact I'll connect this wire together. So, you see, even though the relay here is off, our light is still on here. When will the light turn off when I switch on this relay? If I do it, the NC contact opens up. Because of which the light will go off for us I mean, continuous power will be supplied when using NC. It will turn off when the relay is activated. And if I use the NO contact of this relay Then, the power supply will only proceed if there is no contact. When we turn on this relay here As in the second relay When the second relay is turned on, our second light is turning on. When will it turn on when I switch on the second relay?
