Fig. 4/20 Bus coupler BK-FF, function diagram

The DC 5-V supply required to operate the interface module for bus coupler (N-BK) is obtained from the 24-V supply by a switching controller on the power supply module 6DS1 000-8AA.

The bus coupler subracks can be fitted either in their own cabi- nets or in the cabinet of an AS automation system depending on the type of remote bus coupling.
