The PD300EMZ5-1 Plug-in Lamp Module is designed to provide Z-Wave control to a connected dimmable lamp. The PD300EMZ5-1 module is plugged into any standard grounded AC wall outlet, and the lamp is then plugged into the module. Once connected, the lamp can be dimmed or turned on or off remotely via the Z-Wave controller. The module contains two power receptacles - one controlled, and one pass-through (powered at all times).
