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
Power Supplies on page 110.
