Hi, 

I am working on migrating an old plant. One of the panel have an old Safety relay in it. I need to find a manual for it.

I found a number on it 3TK2807. Do you know where can I get information about this device?

 Dear MicroMan,

please take a look:

Hi,

Thanks for that. Anyways There was no 2807 relay in the PDF. That is the exact hardware I need to migrate, I really need to figure out what it is actually doing and how it suppose to be wired in. The electrical drawings are very poor so I can not rely on just that.
