If you are going to reply, you really should read the postings.
finfin has already said that the internal resistance of the current input card is 250 ohms, and the list he posted already considers that if you work it out.
He also said they are using the voltage card,
and who isn't on a budget. Signal converters are generally quite expensive, though I do agree it is the 'ONLY' option for a voltage signal to a current input module.
The problem with the current input option is still voltage signals normally require high impedance load, however, the 0-1mA option solves that, but with the tradeoff of a very low resolution on the AD converter, making this a bad option.
I don't see why use SLC anyway. Compact logix system is cheaper and produces a better result although you need 4 analog input modules to get 16 inputs. The input modules have both current and voltage on them.
