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.
*1. We recommend OMRON S8[][]-series Power Supply Units for the external power supplies.
*2. The capacity of the external supply current does not include the capacity required by the B7A Link Terminal.
*3. The minimum input time is the minimum time required by the B7A Interface Unit to read the input signals from the
CPU Unit.
