Analog Outputs 2-19
Table 2.B Analog Output Scaling Ranges
Analog Output Configuration Examples
This section gives a few examples of valid analog output configurations and
describes the behavior of the output in each case.
Example 1 -- Unsigned Output Quantity
• [Analog Out1 Sel] = “Output Current”
• [Analog Out1 Lo] = 1 volt
• [Analog Out1 Hi] = 9 volts
Note that analog output value never goes outside the range defined by
[Analog Out1 Lo] and [Analog Out1 Hi], even if output current is beyond
the range defined in
Table 2.B. This is true in all cases, including all the
following examples.
Example 2 -- Unsigned Output Quantity, Negative Slope
• [Analog Out1 Sel] = “Output Current”
• [Analog Out1 Lo] = 9 volts
• [Analog Out1 Hi] = 1 volts
This example shows that you can have [Analog Out1 Lo] greater than
[Analog Out1 Hi]. The result is a negative slope on the scaling from original
quantity to analog output voltage. Negative slope could also be applied to
any of the other examples in this section.
