Figure 3-3 Configuration screens for Current Loop I/O
The current loop I/O configuration settings are summarized as follows:
Label
The identifying label that will appear on the meter screen.
Units
The engineering units the value will be displayed with.
scale values
The minimum and maximum expected current values and
corresponding engineering values for determining scaling. For a
current loop input the values on the left represent the expected
range of current values that the SmartVue may receive from a
sensor or some other device. For an output, the values on the right
represent the expected range of currents that the unit will provide
to an external device. In either case, current values may exceed the
given range since the values are merely used to calculate
corresponding scaled values.
Example: Connect a loop powered transmitter using the SmartVue as the
power source.
In this example a current loop device connected to 4-20mA IN 1, requiring loop power,
receives it from the SmartVue’s built-in supply.
