B7A Interface Unit Section 3-7
3-7-4 B7A Communications Specifications
Note 1. When separate power supplies are used, the B7A Interface Unit and B7A
Link Terminal are supplied by separate external power supplies.
2. When a common power supply is used, the B7A Interface Unit and B7A
Link Terminal are supplied by the same external power supply.
3. We recommend OMRON S8@@-series Power Supply Units for the exter-
nal power supplies.
4. The capacity of the external supply current does not include the capacity
required by the B7A Link Terminal.
5. The minimum input time is the minimum time required by the B7A Interface
Unit to read the input signals from the CPU Unit.
