Chapter 5 Sourcing Current Loop Input Module (1756-IF6CIS) and Isolated Analog Voltage/Current Input Module (1756-IF6I)
Features Specific to the
1756-IF6I and 1756-IF6CIS
Modules
The table lists features that are specific to the 1756-IF6CIS and 1756-IF6I
modules. Each feature is described later in this section.
Multiple Input Ranges
You can only use the 1756-IF6CIS module in current applications. Unlike
other analog input modules, this module does not let you choose an input
range. All channels use the 0…20 mA input range.
For the 1756-IF6I module, however, you can select from a series of
operational ranges for each channel on your module. The range designates
the minimum and maximum signals that are detectable by the module. The
1756-IF6I module offers multiple input ranges in both current and
voltage applications.
The table lists the possible input ranges available for use with the 1756-IF6CIS
and 1756-IF6I modules.
For an example of how to choose an input range for your module, see
page 210 .
