Figure 4.56 Settings to Configure Input 1 as a 4–20 mA Transducer
Measuring Temperatures Between -50°C and 150°C
Analog (DC Transducer) Input Board
Table 4.37 shows the setting prompt, setting range, and factory default settings
for an analog input card in Slot 3. For the name setting (AI301NAM, for
example), enter only alphanumeric and underscore characters. Characters are
not case sensitive, but the device converts all lowercase characters to
uppercase. Although the device accepts alphanumeric characters, the name
AI301NAM setting must begin with an alpha character (A–Z) and not a
number.
