Posted 6 Dec 2011 Wow... I am not sure electronic manuals even existed in the days of the 500 Series. I'm lucky I have found some 800 Series I/O module information in PDF. That stuff is older than PCs... Share this post Link to post Share on other sites

Posted 8 Dec 2011 I have no idea. The 500 series I/O was obsolete long before I ever touched a Modicon. That's a really old and really obsolete product. You can try to contact Schneider Electric since they own Modicon and see if they have any details on that ancient product. Share this post Link to post Share on other sites
