Hi, My name is Ahmad Shamshiri. I am presenting this tutorial from Canada.
Welcome to a video tutorial for Robojax. In this video we are going to
review and see this delay timer with display for home automation.
As you can time on display, you can control an AC or DC load to be turned
off a certain time and also it has multiple programming like four different
programs. let's get started with this.
Hardware Explained
so this is the module. Here and has a 12 volts relay here and the amount of
current is 10 ampere rated either at 30 volts at 10 ampere or 250 volts 10
ampere or 120 volts. 10 ampere multiplied by the voltage will give you the power
that it can control so in these countries with 250V x 10 = 2500W
if you are in North America at 120V , then 120V x 10 = 1205W
and so forth. Here we have three terminals here and
three terminal here. There is the positive pin, it will be connected to 12 volts
this is the GND and the middle one is the input or the signal that you can
bring it from Arduino or from another device. There is an opto coupler that
isolates this. And also we have a voltage regulator here of 5 volts. so if you
connect here 12 volts all the circuits inside will work with five volts and
that trigger also work works with five volts.
so even if I connect it to 12 that's also fine and input will be triggered.
We have here three switch with this one you select which digit you want to change so
this one the blank moves from one to the other one which I'm going to show you
next and with this one you can change the value. Pressing this for long time
will change the program mode from program one program to three and so
forth and here we have three pin for the relay the middle one is a common and
this is the normally closed (NC )if you connect your two wires of the AC load
here it will always be connected which we are not going to use that we are
going to use it this way. The middle one and here and the light is ON the relay
will be ON and these two terminal the two well that you are connected will be connected.
The width of this one is 35 mm thirty five-millimeter
the length is 64
millimeters and the depth of the device is determined by this relay and pin
that are sticking out which is 19 millimeter.
This module weighs 25.6 grams.
Wiring Explained
let me explain the AC bulb here. so this is a table light, this plug is connected to the wall
outlet and the wire goes and will be turned ON, but I have disconnected one of
these two wires here I've just cut this wire from here now this can be connected
to the relay. Job of the relay is to just connect it so it will be ON and
disconnected it will be OFF. I've just twisted them and then put some solder so
this can be inserted into connectors with a screw. There's a wiring now. the
two wires that I showed you for the AC ball who will be connected on these two
side now it's disconnected the one that says what CK and common the matter will
not change CK and common so these are normally open when the relay goes on the
light turns ON. these two wires will be connected. And then on this side there
three pins. This connected to 12 volts, this is connected to the GND of 12
volts this is the trigger which can go with the 12 volts here. So you can
connect and it will work or may be connected from Arduino or from other source
doesn't matter so the middle one is for the trigger which receives the signal
from any other device that you want to control this
P-1 (Programm 1)
this is the zero time as soon as you trigger or the input gets high voltage
and then shuts off then the device stays ON until the time that you're set and
then it goes OFF. So the trigger time is very short here I've just put it long so
you can see it. So it goes ON and it stays ON for very mom sort moment and
then goes OFF. In the graph it was very short I just showed you so you are
not confuse this with something else else. It goes ON and OFF and then the time
stays. here let's go and set this. This is the time that I've shown there that's a
seven-second was 12 seconds that I showed in diagram but here I've set
this because 12 is very long we press this button and then hold it so it
goes to P-1, press it again it goes to P-2 or 3 and 4 and then it comes
back. Once this is in P-1, this button will not do anything the middle
button will make that disappear and then here we can change the seconds with this
button it changed the time so if the decimal point is here then anything on
the left side of decimal point is a second and on the right side is the
decimal point like seven points on one tenth of a second if the decimal point
is here we can move the decimal point or change the value with these two switches, so if I
press this the decimal point disappeared. Now we have 70 seconds it's very long
let me just show you here so it's on now it goes one by one from 70 countdown to
zero now when I press this it just stays on and it blanks now next it goes here
and become millisecond so second and then that would be or one tenth of a
second. Now you can set it for very long period so just
push this and that disappeared now with this one you can select any digit and
change it so when I press it this is now blinking that's a hundred second it can
be changed with this switch I was 370 second so it can go to 999 seconds. If
you want to make this zero just press this update it until it
becomes zero and then use this to move to the next one now this is 70 second. If
you want to make it like five second and at this point make this zero and then go
here and then update it five second and press this and it will disappear so now
it's five seconds. You see that this wire was removed even if you hold it it will
not have any effect. We just need a trigger (a quick contact) after that it stays there
doesn't do anything because the initial trigger was important. So my hand just
touched it so that was P-1
P-1 (Program 2)
when you go to program - it just needs a trigger. It just triggers and a
trigger goes down that then you can set a time after this time the really will
turn ON. from the trigger you can set a time that relay will turn ON. So let's say
you set for three seconds the trigger comes, it is OFF for three second and
then goes ON for the time that you set. So in this mode you are setting two times
the delay time before it goes ON and the time that it is ON now let's set this
for press and hold this until you see P 2 and then press this button so the
first value is the delay time before the relay turns ON. To change it we press this
button here that dot appears which means this is a full second if you want to
change it to smaller than second with millisecond just press this again it will
come here. So if I press this again it disappears. Three thing happens either
it's here here or disappears so here here and disappear. After this if I press
this it will go to the next mode. Let's changes to just five so it's here now
and with this one you make the blink come to four and then change it to five
after this I'm pressing this and it moves to the ON mode and the blank is
here so you can move the blank to any of those so let's just set this to 10 to 10
second, now we have to exit. we have to press it until the dot
disappears. now with this button, so dot disappears
now it's ready. The five seconds delay and 10 seconds ON. so when I trigger it
and leave so 5 4 3 2 1 and then 10 seconds ON.
and then it turns OFF.
P-3 (Program 3)
there's no program tree or P-3 has OFF time and ON time. It doesn't need
any trigger as soon as the device is ON it goes OFF and ON and stays
ON and then goes OFF stays OFF and so forth it just continuously going. So you
will set two times so the OFF time and the ON time. when you set the OFF time
that light on the device will be off and when you set that ON time the light
will be on OFF. Press this button and then hold it so it goes to P-1. Press it
again it goes to program 2 or P-2. Just press this metal button now this is
the ON time automatically it starts because it doesn't need any trigger to
change it, press this and now we are in ON and it
stays it allows you to change the value. but with this one you can select the
blinking bring the blinking so the blink comes here and now this is the OFF time
because this is off this is the off time so 21 second if you if I change it to be
hundred and something so move this.
so I'm gonna set it at eight seconds make this zero. Now that it's the
kind of fact I will press this until the light is on when the light is on that is
the on type so this is on time now move the blinking with this let's say make it
five seconds five point eight seconds
let's go five point eight and then you see the off time one point two five
point eight on/off on/off continuous like that
P-4 (Program 4)
P-4 or program 4 is such that the trigger happens and stays ON, and from
the time that trigger stops the countdown starts. So if you set it let's
say for 6 seconds when the trigger stops that time can count down until
it's zero and then the relay will go disengage or disconnect. So have a look
here so now I'm going to P-4 so now I'm in P-4. Plus this so this is
14.7 it with each. So let me make it smaller to change, now
it's 147 second so let me just change this to 5 seconds or 6 seconds
now disappear. Now look at this, no dot. Nothing. Now when I connect this, it's on
as long as the trigger is ON (or connected) the relay is ON but when I remove my
hand from 6 the countdown starts toward zero. Off now
have a look here again this time I'm gonna disturb (disconnect) it again at the middle of
countdown I will connect it and you will see. so this is ON when I remove it the
countdown starts but if I connect this again the counter resets and it starts from the
beginning so , 4, 3, 2 I connect it again it goes back to the
set time of 6 seconds and start and then we'll countdown until zero. And the relay
will turns OFF. this device doesn't have any manual they've used some kind of
translation from Chinese to English and and after the description this is what
they have for this every website every Chinese website is using this and it
seems this has been translated with Google or some other software from
Chinese many of the words that they are using they don't make sense if you
follow it. So I'm going to publish a manual for this one so people can
download and use. This is a very useful module for many application
with four different programs and time settings. Definitely it can replace a lot
of other devices I recommend this if you're using it for
time control devices. Thank you for watching please thumb up 👍 the video
