00:00Assalam-o-Alaikum, In this video, we are giving you information about an IC.
00:10This is Ju-LN2003 IC. It is installed in this part of the kit.
00:16You can see here.
00:17It is installed here.
00:19I will try to give you information about it.
00:22How does it work?
00:24What is its function?
00:25How does it work?
00:26It is installed in almost every indoor and outdoor kit.
00:32It is installed in almost every company's kit.
00:35This is a switching IC.
00:37You can see here.
00:38First of all, I have put a relay in it.
00:43It is a transistor.
00:44These guys have come to us to work.
00:48Okay.
00:49I told them that I will explain to you and you will also know how it works and what it does.
00:57Look, there is a microprocessor in every kit.
01:02My video is complete on it.
01:04You can watch it on the channel.
01:06What is its function?
01:08How does it work?
01:09But today we will talk only about this.
01:11And I will explain to you how it works.
01:13What are its functions?
01:16Look at this.
01:17This is a transistor.
01:19We have this.
01:20My entire movie on transistors is available.
01:23You can watch it.
01:24You can understand it.
01:25You can do it.
01:26I have explained this to them.
01:31I have explained to them that this is a relay.
01:34How is it operated with a transistor?
01:37Because this IC is in it.
01:40Look at this.
01:41There is a small one in it.
01:42Maybe you will think that this is small.
01:43He is sitting with a big one.
01:45This is in it.
01:46It comes in SMD.
01:49This is a transistor.
01:50There are two types of transistors in it.
01:53One PNP and one NPN.
01:57I have explained to them both that what is the function in them?
02:00What is the difference?
02:01How to check them?
02:03How can you find out how the base collector emitter is in it?
02:08And how can you connect it and turn on the single relay?
02:11I have shown it on.
02:14My video is available.
02:15You can watch it there.
02:17What is the function of this transistor?
02:19How to check NPN?
02:20How to check PNP?
02:21The video is available on the channel.
02:23Yes, sir.
02:24Did you understand this?
02:26Yes, sir.
02:27Sir, I am asking you this.
02:28This is in the relay.
02:29This is in the positive.
02:32No, it is not in the positive.
02:34It is not in the positive.
02:35In this, as I have explained to you earlier,
02:38that this is our transistor.
02:41Which one is this?
02:42Which one is this?
02:43PNP.
02:44It is PNP.
02:45Yes.
02:46The work of PNP transistor,
02:48this is the purpose.
02:49Look at this.
02:50I have told you all this in detail.
02:53Look at this.
02:54There is a base collector emitter in it.
02:56As we are from the meter,
02:57I have told you to check this whole thing.
03:00Look at this.
03:01I will tell you again.
03:03I have put the meter.
03:04Look at this.
03:05You have put the meter.
03:06On whom did you put it?
03:07Diode mode.
03:08You have put it on diode mode.
03:09Look at this.
03:10By putting it on diode.
03:11When you put it on diode mode,
03:12we know about it.
03:14This is the collector,
03:15this is the emitter,
03:16this is its base.
03:17Look at this.
03:18I have put a probe on the base of this meter.
03:21Look at this.
03:22I have checked it.
03:23It did not give any reading.
03:25No reading.
03:26No, no.
03:27Look at this.
03:28Now what will happen?
03:29Look at this.
03:30The rest of the video is there.
03:31If my other brothers are watching,
03:32they can watch.
03:33Look at this.
03:34This reading came on it.
03:35Yes.
03:36And this came.
03:37There is one N in this.
03:38Neutral N.
03:39And two positive.
03:40P.
03:41Positive P.
03:42This is also P.
03:43This is also P.
03:44Two P's came.
03:45Whatever is in the center,
03:46that is the base.
03:47Base is always written in the center.
03:48Yes.
03:49P and P-adjuster came.
03:50Yes.
03:51Now to turn it on,
03:52you have to run
03:53anything on it.
03:54You have to turn on something.
03:55Yes.
03:56So,
03:57as you have to give current,
03:58so positive,
03:59you give anything.
04:00Look,
04:01we made this relay.
04:02Yes.
04:03We are giving its coil from here.
04:04Okay.
04:05Yes.
04:06And the one who is giving it negative,
04:07we are giving this one.
04:08From here.
04:09From here.
04:10From the collector.
04:11From the collector.
04:12And this is its base.
04:13Yes.
04:14Obviously,
04:15if you see from here,
04:16then you will understand
04:17this thing very easily.
04:18Look at this,
04:19the collector also came.
04:20It came.
04:21Negative came.
04:22Neutral,
04:23okay?
04:24Yes.
04:25Ground.
04:26Yes.
04:27When we gave ground to it,
04:28from here,
04:29and look here,
04:30it has to pass
04:31with switching from here.
04:32Here.
04:33Yes.
04:34Okay?
04:35On the coil.
04:36Yes.
04:37On the coil.
04:38Yes.
04:39Which one did we get here?
04:40It got ground.
04:41Ground.
04:42And the base,
04:43we put resistance from here,
04:44because if its beta value
04:45increases,
04:46then the transistor will burn.
04:47It will burn.
04:48Look at this,
04:49we put 2k resistance
04:50and switched it on.
04:51When it was switched on here,
04:52then from inside,
04:53it got negative from here.
04:54No, no,
04:55positive,
04:56the system inside it
04:57needs positive.
04:58So when we gave it,
04:59it switched on the relay
05:00here.
05:01Yes.
05:02Okay?
05:03Which transistor is this?
05:04This is TNP.
05:05TNP.
05:06TNP.
05:07TNP.
05:08Yes,
05:09this is the same,
05:10same,
05:11look here,
05:12it has the same method.
05:13Yes.
05:14Now I will explain it to you,
05:15look here,
05:16it has the same method.
05:17It became the same thing,
05:18our IC.
05:19Inside it also,
05:20all your TNP transistors
05:21are installed.
05:22I switched on the supply,
05:23from here,
05:24I,
05:25because,
05:26look here,
05:27in this,
05:28the main thing is that
05:29here,
05:30on 12 volts,
05:31on 24 volts,
05:32on 30 volts,
05:33when it operates,
05:34it has no problem.
05:35But,
05:36yes,
05:37because,
05:38now in this,
05:39this is LV,
05:40this is on low voltage,
05:41I have put a resistor
05:42of 1K in it.
05:43Yes.
05:44It will work
05:45on the same method.
05:46Now I,
05:47look here,
05:48it has this,
05:49from this side,
05:50I told you before,
05:51that from here,
05:52look here,
05:53this is installed,
05:54this one is installed,
05:55this one,
05:561,
05:572,
