I just generated a functional simulation model for a DPDT relay symbol I had previously downloaded (both attached).
It includes an approximate 15ms open and close delay to simulate the mechanical relay operation.
I'm posting it for others to use because I wasn't able to locate such a model elsewhere.
I've also posted it in the Yahoo LTspice Users Group.

Edit: The .asy file can be put in the sym/Misc folder, and the .sub file goes in the sub folder.

 

A useful addition, thanks Carl.

hi,
Run into a small problem with file naming, there is already a Switch Model in the LIB/cmp'sub folders, with files named DPDT.sub and DPDT.asy

E

 

Just rename the new files as DPDTc, or similar.
Over at ETO I suggested replacing the absolute path to the diode library with a relative path: .lib standard.dio, to allow for non-default installation locations.

 

hi Alec,
Already renamed, to RelDPDT,
Ref the standard.dio possible path problem, did encounter that also.

Works OK,
For Old XP Pro users the (x86) entry in the .lib C:\Program Files(x86)\LTC\LTspiceIV\lib\cmp\standard.dio needs deleting in the sub file.

 

Okay.
Thanks for the update.
I changed the standard.dio line to relative in the sub file.

Those aren't files that came with LTspice, are they?

 

hi,
They are from the Yahoo LTS user group site.

I see you have DPST.sub for download but your DPDT.asy calls for a DPDT.sub

Is this correct ?

 

hi Anton,
This asc has various relays.

Thanks Eric

Much appreciated !

Hi Eric

I opened the relay_test1.asc schematic file but it has no symbol for all of the test relays. Is there something I am missing ?

 

Woops!.
Added the relayasy zip to post #11

Great, thanks. Now it works.

There’s one in the relay lib at LTspice group.

I modified the relay model so you can include the relay coil resistance and nominal coil voltage by right clicking the relay icon.
The relay operate voltage is set at 70% of the nominal coil voltage.

Thanks.
They work and nice touch with right click to alter the nominal resistance of the relay.

Hello, I put these in their respective folders and cannot find them when I want to place them on a schematic. Seems they have to be imported or registered with the program, can you give any pointers. Thanks.

Did you close and reopen LTspice after you did it?
