BKxx00, BKxx10, BKxx20 and LCxxxx
The Bus Couplers / Bus Terminal Controllers require an operating voltage of 24 VDC.
The connection is made by means of the upper spring-loaded terminals labelled 24 V and 0 V. This supply voltage is used for the electronic components of the Bus Coupler and Bus Terminal Controllers and (via the K-bus) the electronic components of the Bus Terminals. It is galvanically separated from the field level voltage.
