That may or may not help, as "12566" means
lots of different things and
doesn't describe an exact board - GRD TRU, + TRU, Microcircuit Interface,
Printer interface... all slightly different variations of the boards
generically marked 12566. In other words, 12566 is not specific enough, you
need the rest of the letters & numbers after it to know exactly what it is.
Some of the variations are just different wirings (and in some cases I think
a different chip or two) giving different electrical characteristics but the
boards look almost identical to the naked eye. The 12566 boards that I
desire, don't look anything like the "normal" 12566 boards. The ones I
want
are labled 12566-60032 and have boatloads of dip jumpers on them, no solder
jumpers.
I didn't realize there was much difference between the boards other
than the obvious GRD TRUE vs +TRUE versions. I checked and I have
some 12566-80024 +TRUE, some 12566-80024 GRD TRUE, but only one
12566-60032 Microcircuit. What makes that version specially suited to
your applications?
I also have some 12551-8001 Relay Out boards and then some 11629-6001
44 BIT GPO boards for which I cannot find any information.
