analog input question

[John_R]

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..

Please post PLC model or IO nameplate. Analog input hardware is not the same for built in, snap or separate IO module.

V560 with a V200-18-E3XB snap IO, or alternately an external IO-A18 module...

Both the -EX3B and the IO-AI8 will read 0 on a negative input.
