The LightLEEDer-EVO is a distributed lighting control panel that simplifies installation. The LL-EVO can be expanded from the local port using a LL-EVO-RC, LL-EVO-4X, and/or LL-EVO-8X. This panel operates the R20 style relays that connect using a standard CAT-5 cable. The remote mounted R20 relay is suitable for lighting or plug-load use. The LL-EVO has 16  pre-programmed lighting applications, push to connect terminals with color coded labels, internal time clock, and galvanically isolated 0-10V dimming. The LL-EVO can operate as a stand-alone panel or networked, reverting to stand-alone automatically if the network is interrupted. When installing, simply set the panel for a lighting application and it is up and running. This allows the installer to confirm wiring and fixture performance from the start saving time and start-up expense. Each of the 16 application programs can still be modified or customized using the standard ILC software. The remote mounted R20D relay has both line voltage and the 0-10V dimming control wire leads for easy wiring.
