XPCP Passive Coupler
Passive 2 phase 1:1 2 line coupler
The XPCP Passive Coupler is a tuned circuit that mounts at the electrical panel to couple X10 signals from one phase of the 220V line to the other. Use this device when you need to continue power line carrier signals past an isolation transformer, or other low pass filter. It can also be used to ensure that power line signals from two or more SB1800Us are communicated to all phases in a residential installation.
