The LightLEEDer-4RC Room Lighting Controller (LL-4RC) is a 4-relay full feature integrated mini panel with the common features desired for today´s 1 or 2 room control. It has been designed to be used as a stand-alone panel or can be used as an expansion or remote panel from a standard LightLEEDer panel´s local port. As with all of our LightLEEDer panels, it comes with our Reliant40 latching relays which feature a superior four contact design - the first true 40Amp lighting relay. It also has integrated electronics for 4 dimming outputs for controlling 0-10V dimming ballasts, 2 inputs for photocell heads, 4 hardwired inputs, power for occupancy sensors, and a local LightSync port for up to two 6 button data line switches.
