B7AP
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.

Note: 1. The value is for the case where a power supply is provided only for the B7AP-S1.
2. Minimum coupler interfacing time is the minimum time required for signal and power transmission between the B7AP-S1 and
B7AP-M1 Power Couplers.
