Analog Input
The Analog Input software point provide a mean for converting a 4-20 mA signal into a useful
data value, such as level or temperature. The Analog Input point provides an offset value (Zero)
and Scaling value (Span) for converting the 4-20 mA signal. Measurement units can also be
associated with the 4-20 mA signal. The conditioned Analog Input value can be used as the
data reference for the transmitter level or temperature, can be displayed on the LCD, or can
be used to drive a 4-20 mA Output channel.
