Opto22 G4 8-channel I/O Module Rack
Archiver
Posts: 46,084
Hi, Andrew. I'm planning on using the Stamp Controller Interface
Board and the Opto-22 I/O module rack in my project, (which involves
turning on& off AC loads.) The CI board has some ULN2003 chips
(darlington drivers), according to Jon W. and John B.. Here's a link
to the TI datasheet, with application examples:
http://www-s.ti.com/sc/ds/uln2003a.pdf
The stamp pins can connect directly to the input pins of the 2003.
The (+) logic pin of the output module is connected to +5V.
The (-) logic pin of the output module is connected to the output pin
of the 2003. Don't forget ground. When the stamp pin goes high, the
output module turns on.
I haven't gotten the boards yet (waiting for purchase order
approval), but when I do, I can tell you more about how the resistors
and 2003 are wired to the stamp pins. Come to think of it, a
schematic of this CI board would be very helpful.
The Opto 22 web site has lots of information:

The board that Parallax sells is #G4PB8.

the Stamp Controller Interface Board. There's a code sample at the end of the
AppNote on how to read in from a Digital Input module and to set a Digital
Output module.Kevin K AsatoKC6POB--- manwithapipe wrote:> I am beginning a
