Hi, I have analog load cell 0-10V feeding into 1771 Analog Input card.
I scaled it simply
0-20,000 <=> 0-4096 counts <=> 0-10V
for multiplier of 4.88
Now I have some doubts since the spec sheet mentions input/output resistance of load cell being 350ohms and I am not really sure if that has anything to do with voltage drop on the PLC card (250ohms) and if my scaling might be out of whack ?
