Chapter 3 Module Features
Multiple Input Ranges
You can select from a series of operational ranges for each input channel on your
module. The range designates the minimum and maximum signals that the
module can report. The following input ranges are available on the high-speed
analog I/O module:
• -10…10V
• 0…5V
• 0…10V
• 0…20 mA
For an example of how to choose an input range for your module, see page 77 .
You must wire the module differently, depending on what operating mode, such
as current or voltage, you plan to use. For an example of how to wire the module,
see
page 63 .
Underrange/Overrange Detection
This feature detects when a high-speed analog I/O module input is operating
beyond limits set by the input range. For example, if you are using the 0…10V
input range and the module voltage increases to 11V, the Overrange detection
feature detects this condition.
Table 7 lists the available input ranges and the lowest or highest signal available in
each range before the module detects an underrange or overrange condition.
