Analog Input Configuration Example
When configured as an analog input, the channel accepts a 4–20 mA analog
signal. The accuracy of the analog input is better than ±0.5% of 20 mA over the
temperature range of the product. Engineering units and ranges are assigned to
the 4–20 mA current input values. Additionally, low-low (LoLo), low (Lo), high
(Hi), and high-high (HiHi) levels can be defined. The Boolean outputs associated
with these levels for the analog input can be used in the user configured
software. There is also a Range Error output to indicate that the Input is outside a
2–22 mA range.

The Analog scaling must match the actual unit hardware, or the
signal sensing and all association protection and functionality will
not work correctly.
