*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.
*4 When a common power supply is used, the B7A Interface Unit and B7A Link Terminal are supplied by the same external
power supply.
*5 When separate power supplies are used, the B7A Interface Unit and B7A Link Terminal are supplied by separate external
power supplies.
