What Types of Signals Used in Instrumentation & Control | What is DI, DO, AI, AO Signals in Hindi

Hello, welcome back to my YouTube channel Electro-Skills Engineering And friends, I'm going to make a video today about this. There is one who is an interesting topic whose name is What kind of signals do we have in the instrumentation I was in the video and I was telling you guys. Both signals are apparently the same. But what is the basic difference between them Which we call input. And it's called output. I'll tell you later. Other What to do When you get your signal out And it goes to the PLC input So we put him in Which is called a detailed input signal. Either it will have a zero bolt signal Or there will be a 24-bolt DC signal - I'm not. It won't send any more signals between them. It's either 24 V. It's either 0 V. In the same way it is a proximity sensor If something comes in front of it, what will it do by detecting it? This 24 V leak will and 24 V what will happen Let's take a look at it a little bit and see if we can get it. The only thing I can see is that Look at this. We have 24 V DC PLC input terminals. But here we have some of these way 6 terminals The PLC's D.I.E. Now all these signals that are said At the input of this PLC I have 6 kinds of It's got sensors. There are limit lists and proximity sensors. What are they gonna do? I 'll wiring them. So their output will be They're called in 6K6 terminals 0 Zero to take 5 terminals will be connected Goes when there's an object in front of it. So its bar will give 24 walls and this This terminal will go, here it will sense Pilssy. This way when your limit is reached, The 24th Wall's signal will go to this terminal. What do we have this way? There's a digital input signal. So this is going to be 0, this is going to be 24. If it's 24 hours, it will make a lot of sense. In the same way, let's see some more examples here. The first execution I showed you. The one we have is a modulator. This is your compact. The word "compact" means, Input is also in this, output is also in this. But next thing I'm going to give you an example, this is an example This is a modular PLC. Its power supply is connected, its PLC module is connected, Then his DI cards are aligned. There are digital output cards. Now this is digital input card. When your PLC is modular type, where are all your terminals? Your digital input card will be connected. And it will have the same principle, 0 or 24 coal. Okay, I hope you understand, this is a DI card. Now we understand the Digital Output here. What will happen on the digital output, as we saw above was the input, In the same way below you will see, these are outputs, From our output terminal. PLC which is ours, it is compact type, Compact type of matsab power supply also in this, Input Channel also in this, Output Channel also in this. You see its direction, it's going through the PLC, They have no signature, 24V. Well, now that Dio is with us, That you, if you have a Transistor type, So you can only get 24V output from it, Or you can get it to act. But if your PLC is what it is, The relay is PLC type, So you can also take 24V DC from it, And can also take 220V AC, So if the relay type is your PLC. See, here on RLY it says, Relay, that means, I can turn on 220V things from here, Okay, I'm going to go. But if you don't have a relay here, There's a DC written on it. the relay's wake, Or it would have written T, So I could only operate 24V here, This is an additional thing I'm telling you guys, Now what do you want? It's all right. Amesha, as soon as you have the sensor, So the sensor will send a signal, This is a signal, The sensor is a signal, Remember this too, In interviews, people ask, The command signal is to Pilssi is interested. I can't see who's in command. If there was a sensor, the pill would have a signal. Input is digital input And if the pill will send a signal So what's this gonna get us? So what do you have? Sensors, connected with digital input of PLC And who are your actuators They connect with the PLC's output channel Look at this and I'll amplify it. Look at this relay output. Here you have four I have There is no electrical terminal. 0, 1, 2, 3 now in these four terminals What have I done? I kept them connected. Well, it's like I said before. You guys are like this You have a contact Tuls It has all the inputs too. And the food is in the same box. But what happens What will happen? It also has different bordels. You can also get these 24 walls and 220 walls. You can generate a signal from it. So this is an ABB extension card, You can also use it in this way, it has to be checked that this card which is your relay type is or transistor type is, I've told you, you guys are fine. Like we saw in the data input data output, or so is no, or is 0 volt, or is 24 volt, right? But what happens in it, it has a range, nLog whenever aAja it will have a range, This means, from 0 to as many numbers as come, up to 10, all that, what you have, will be an analog signal, it's a DC signal, 0 to 10 volts, right? Now what happens, it has two kinds of signals, one voltage type, which we call, son, 0 to 10 volts DC, and one what happens, we have current type, it is 4 to 20 milliamp signal, Now on what basis we will use 0 to 10 volts DC, and on what basis we will use 4 to 20 milliamps, this I also tell, look, this is a sensor, Artydi is, Four Gampel, it is a putanchio meter, or else you have We'll get rid of this thing, and we'll get rid of the tracer. The pros are talking to the other person. So what this will do is the sensor will be able to generate these two kinds of signals only So it's 0 to 10V AC or 4 to 20 mA Now let's see when we get 0 to 10V and when we get 4 to 20 mA Unlog input uses Look, what's happening, children. The toilet distances are when you have 50 feet of At least this one you have. Maximum that a request date you have a limit What is that? That is if your card is PLC Or your PLC's channel. If your sensor is more than 50 feet away Okay, so you can 't use the 0-10 wall. But if the limit is within 50 feet So you can use 0-10 Wall DC Why son I'm telling you 50 feet Because son look this is 0-10 Wall DC When your length sensor and gut will also increase by 50 feet This means the wire's distance will increase. When the distance of the wire increases, the length of the wire increases Your distance will grow So we will avoid the Jiru Tu Tan Wall Dishi Here I have told you That's the limit that's yours. Maximum that is limited to you. What is this? It's 50 feet. This is AI talk. I unlogged input. But when the full fifty feet are talked about We need to find out what we need. Then we will use 4 to 20 milliamp signal to Now 4 to 20 milliamp signal We'll see the same way to PT. See you in T.T. Your level will be seen on the transmitter Or if there is an RTDA thermo coupling Like a transmitter like him. What are we gonna do? a signal of 4 to 20 mA We will draw 4 to 20 mA signal will be Long He can trawl in Dissent Why can 't you, son? If the length of the wire is too long So does it matter Because what happens now stays in the series. So you send a signal of 4.5 mA No son, it's exactly the same. regardless of the distance No matter how much dissent it doesn't matter So this thing made sense But what happens in one more thing let me tell The signal of the 4-20 mA signal According to 0-10V signal There's a very small signal. Its that its cable coming on long distance With safety But it has a coating on top of it. There is a congestion cable. What happens above it If you understand We send him in coats. Because your 4-20 mA Signal is on. What if someone else With wire What if? But there's something For the Council But your Samano But by doing it, I'm going to go. I need to go. of the same And if your control valve or BFD is away from it, what will you do? You won't use 0-10V in it, it'll take away 4-20mA. And within 50 feet, you can get a 0-10V DC signal, right? You see what happens, the speed control of the BFD if we turn the PLC, So we have its AVI, it's the analog voltage input which are terminals, We use it to control it there. In the same way, how much to open the servo valve, how much to make, Command signal will be sent, output which happens, Who's going to go, son? Your servo goes into the valve, your servo goes into the drive, okay? In the same way, the Control Valve has to be opened, how much to open, When you drive the car, you open it with the AO. There was also your "Push to Pressure" There's an I.T.P. converter that you put in. That's a different thing when you If you want to make a video, do it. Okay then after this 0-10 of Wall After 4-20 milliseconds we see that it also came in That's what you'd do for long distance 4-20 miles. Will you use your A.O. card? If you like the video, like it.
