Description: 32-Channel 5A SPDT RS-232 Relay Controller with XR Expansion Port
We have one of these that was purchased in August 2008. Is documentation for this unit available?
Thanks,
Ken
Hi Ken,
You should find most of what you would need under the resources section of this product page:
If you have further questions please post a photo of the board so I can see exactly what you have.
Thank you,
