Models UFR/UFD are wire-in fixture modules designed to control the operation of 120VAC appliances, ceiling fans and lighting based on digital commands received over the powerline. These modules communicate using the highly-reliable Universal Powerline Bus (UPB) technology. UPB devices such as these are easily integrated to provide a flexible, low-cost alternative to hardwired or RF home automation strategies.

These modules fit easily inside a standard outlet box, or they can be mounted to other surfaces using screws/ties. Fixture modules connect directly to the existing household power wiring. The device connected to the module can be operated manually using a UPB wall switch or multi-button controller, or automatically via PC or home automation server.
