LightSync Digital 4 Load Room Controller

Model: LS04-RC

The LightSync 4 Room Lighting Controller is a full featured panel with the common features desired for today’s 1 or 2 room control. The LS04-RC is available with 4 or 2 1-pole relays. 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 or LLEVO panels local port. The LS04-RC comes with our Reliant40 latching relays which feature a four contact design - the first true 40Amp lighting relay. It also has integrated electronics for four dimming outputs for controlling 0-10V dimming ballasts, two inputs for photocell heads, four hardwired inputs, power for occupancy sensors, and a local LightSync port for up to two 6-button data line switches.
