X-10 Filter/passive coupler (DIN mounted)

Filtering
Interference can be caused by appliances that do not conform to the C-Tick regulations, or by wireless intercommunication systems which use mains borne signalling. The latter transmit high frequency signals into the mains network. The filter/phase coupler suppresses noise caused by external factors, while the unique filtering techniques of the X10 system ensure internal interference is insignificant.

Coupling
The FD10 also includes the ability to couple X10 signals across phases. For installation with three phases, use three FD10 filters and couple the filters by connecting their terminals K to the next phase, respectively.
