hey
m using 12v relay
i need to knw the pinout
the serial number is
shenle
jzc-20f(4088)dc 12v 5a

hi,
I have looked for the datasheet, no luck.

Do you a DMM.?
If yes, its fairly easy to work out the pins.
The coil will be a resistive value, greater than zero.

Once you have the coil winding, apply 12V ON and OFF, while you measure the contact pins.

Obviously the contacts which are normally closed are the easiest to measure, when you have done that apply 12v to the coil and measure the contact pins again, this should identify the common/wiper of a contact set.

Do you follow this.?
 
yes
i have DMM,
whats the value it will give..in ohms?i have to check its resistance..
how to know which one is ground?
from where i have to apply 12v?
one by one all the legs..
c the picture and please make me clear!

It will give a resistance of say 100R upto about 1000R or so.

how to know which one is ground?
On the relay coil is dosn't matter.

from where i have to apply 12v?
Either end of the coil is OK.

one by one all the legs..
c the picture and please make me clear!

Hi,
Is this clear.?

I have looked at the picture, use any end of the coil for 12Vdc and the other for 0V
 
allright!

well in the picture one is connected to the other leg ..
so there will be four leg..
so i just have to put 2 legs as on and off...and other two legs with the output or what else..???????
well this one is transparent,so only from out can i judge?
or i hvae to measre it by DMM ?

hi,
Look at this drawing.

The relay is a single pole change over, like a single pole change over switch.

Show us the circuit where you want to use the relay.?

EDITED:
Showing relay states.

hey Gibbs
i dunt have my ckt soft copy in which i hv to use relay..
basically im using it in ir reciver ckt...!
after relay there is dc motor with scr..
well,
ru sure this pinout is write..?
now i think i can easily connect relay in this way with my circuit..:)
should i..????

Thank you v much :)

This is what your data sheet says.

now i think i can easily connect relay in this way with my circuit..:)
should i..???
YES, whats the alternative.? are we going to keep exchanging posts for ever. just do it.!should i..????

Thank you v much :)

hi,
If you are ever unsure about the motor to relay connection then before you
connect the motor use a DMM, on ohms to check the relay contacts, NOT the coil.
Good luck.:)
