Note 1. The transmission distance also depends on whether a common or separate power supplies are used.
2. The minimum input time refers to the minimum time required for reading the input signals from the CPU
Unit.
3. The ON/OFF width of the signal transmitted from the CPU Unit to the Output Relay of the B7A Interface
Unit should be set to a value larger than the minimum input time.
4. The capacity of the external power supply does not include the capacity required by the B7A Link Termi-
nal.
