I/O Interface
Section 10A
10A-48
The E--Series analog I/O module allows you to select between bipolar
operation (--10V to +10V dc) and unipolar operation (0V to +10V dc).
Select this using a dip switch located next to the node address switch (see
Figure 10A.38). Bipolar or unipolar can be selected independently for the
input and output channels.
