Simon,
Thanks for the suggestions. I need to stay as close to ALL-IN-ONE unit unless I expand the number of A/D inputs.
However, I am still a bit lost with the description of 4-20mA inputs as found in their docs.
For example in V-350-35-TRA22 it says...
"... Normal mode
Resolution, except 4-20mA 14-bit (16384 units)
Resolution, at 4-20mA 3277 to 16383 (13107 units)
Conversion time 100mS minimum per channel. See Note 4
Fast mode
Resolution, except 4-20mA 12-bit (4096 units)
Resolution, at 4-20mA 819 to 4095 (3277 units)..."
What are those magic numbers 3277 to 16383 (13107 units) and 819 to 4095 (3277 units) ?
Is it 12-bit or 11.5 or ...?
