Analog Range Selection
The analog input range selection is accomplished by proper wiring of
the input channels.
Valid Input Data Word Formats/Ranges
The analog input data received at the module is converted to
RAW/proportional data format. Unlike the 1769-IF4 and 1769OF2.
on-board scaling is not provided by the module. You must do this via
your control program.
The following table shows the valid input data format for the data
range provided by the module.
