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.
The ON/OFF width of the signal transmitted from the CPU to the output relay of the B7A Interface Unit
should be set to a value larger than the minimum input time.
3. The capacity of the external power supply does not include the capacity required by the B7A Link Termi-
nal.
Maximum Current and Power Supplied
There are limits to the current and power that can be supplied to each Rack and Unit. When designing the system,
take the current consumption into account.
Follow the chart below and be careful that the total current consumption does not exceed the maximum current
and maximum total power supplied.
