Note: 1. The maximum I/O points refers the maximum I/O points handled simultaneously by the B7A Input and Output Units. Figures in
parentheses
indicate the maximum I/O points handled simultaneously by the B7A Input and Output Units each connected with an
independent
power supply
. Refer to
Power Supplies
on page
110.
2.
The maximum I/O points are the same as the maximum input points of the B7A Input Unit connected to the B7AP-M1.
3. PLCs
and three-wire sensors can be connected only
if the B7A Input and Output Units are each connected with an independent
power supply
. Refer to
