 
Hi Friends! I hope You all 'll be fine
You are watching AJ Electric YouTube channel
and my name is Aamir Jamil
Today video is about time relay
timer relay is a time operated relay
by which we can switch any 2 or more than 2 loads
 
 
for example
we want to control 2 loads in our home
on two different locations
first is load 1
and another one is load 2
and we want
on or off any individual load or lamp after few minutes
however which time we selected
 
for this purpose we use timer relay
so how we use timer relay??
and what is the circuit ?? and how we adjust the time
so lets start
I am going to control two loads
 
 
but firstly i request kindly subscribe my channel
and press bell icon for more videos
 
 
 
 
so firstly i start from construction
 
if i open upper portion of timer relay
 
here you can watch 8 terminals
so how these are connected with each other
for this we want to understand the circuit diagram of timer relay
so i make circuit diagram
 
so here is the 8 terminals
are connected on the plastic base
I draw 8 terminals on this board
sequence of these terminals are
 
If you see on this base
 
terminals are start to 1 on right bottom
and moves upwards anti clockwise
 
so these are total 8 terminals
now we see inside
2 and 7 terminals are coil terminals
 
it means 220v AC supply will connect on 2 and 7
it means 220v AC supply will connect on 2 and 7
 
coil operated voltages are 220v AC
 
you can see the two terminals
 
from right side
on bottom is 1 and on opposite side 4
1 is normally closed to 4
and normally opened with 3
 
same like that 8 is closed to 5
and normally opened with 6
 
so after turned on the supply
 
normally closed will going to opened
and opened will be closed
 
so suppose we are connected 2 bulbs on both
 
so after turned on the supply
terminal 4 is going to off position from on
 
and after completion of selected time 6 or 7 seconds
terminal 4 bulb will off and 3 will on
so I connect 200 Watts lamps
how timer relay is work
 
but one more thing is important to know
 
how to set the time on timer
so open the cap
here you can see this tag is for 10 seconds
 
so remove this with any screw driver
 
after removing there are 1 more tag
 
If we want to set the time for only 10 sec
and If turned back
this will be worked for 1 sec
other tag is for 60 sec
and opposite side is for maximum 6 minutes
 
 
so If you can use this 6 min tag
here is the switches position is on 1 and 3
 
total number of switches are 1,2,3 and 4
 
 
 
 
so put it set on 1 and 3
and adjust the tag on timer body
 
same like 1 sec
 
switches position will be 2 and 4
 
these switches positions are also draw on it body
 
these switches positions are also draw on it body
 
 
 
so Here I use 10 sec tag for my experiment
 
I adjust switches position on 1 and 4
 
 
 
 
I have 2 lamps of 200watts
 
so now I control both with this electronic timer relay
 
here you can see the circuit diagram
 
 
 
4 is connected to a lamp 1
and 3 is connected to second lamp
 
 
so after turned on the supply
NC lamp will on
and after time dependently switching
NO lamp will ON
 
and neutral of both lamp are common
 
2  and 7 terminals for 220v AC supply
so here you can two wires for supply
 
we also provide voltages to lamps so
I connect 2 and 1
 
 
and 7 is for neutral
so connect the lamps neutral to timer neutral
 
so now mount the timer body on the base
 
and adjust the time on display
5 Seconds is enough
 
 
now connect 220v to supply terminals
 
 
so time to test
 
so after turned on the supply left lamp will glow for 5 sec
and after 5 sec right lamp will glow and left will off
 
 
 
 
 
here you can see the switching
 
again
 
now I set 4 sec
 
 
 
 
 
 
 
so we can control 2 circuits or
4 loads at a time
 
 
I hope this video is knowledgeable for you
