John_R Posted July 16 Report Share Posted July 16 Hey all, Simple question about vision analog inputs (I hope).. what happens if I feed a negative voltage into a 0-10V analog input? does the associated MI go negative or does it just stop at zero? really didn't see anything about this in the help files. figured I'd ask before chance damage to my hardware..

Analog input hardware is not the same for built in, snap or separate IO module. Link to comment Share on other sites More sharing options...
John_R Posted July 17 Author Report Share Posted July 17 V560 with a V200-18-E3XB snap IO, or alternately an external IO-A18 module... JohnR Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted July 20 MVP 2023 Report Share Posted July 20 Both the -EX3B and the IO-AI8 will read 0 on a negative input. Joe T. Link to comment Share on other sites More sharing options...
