LightLEEDer-EVO Remote 20 Relay

Model: R20

The ILC Remote 20 (R20) and Remote 20 Dimming (R20D) relays are designed to be mounted at the power junction box or lighting fixture for direct control of the lighting load. Relays are controlled from the EVO panel using a standard CAT-5 cable connection to the R20 relay RJ-45 jack for easy installation. The R20 series relay uses oversized contacts designed to  handle LED inrush current, tested at 16 Amps electronic driver that can commonly exceed 200% of running current. The R20 is a latching relay to eliminate power consumption. The R20D has galvanically isolated 0-10V dimming from the LL-EVO panel for direct wiring to the dimming driver without needing to pull separate 0-10V wiring back to the controller. Power loss failure at the EVO panel will force dimmer output level to 100%.
