Your obvious solution for centralized relay control, the LRC2410 has an integral time-clock, photocell, occupancy, and override switch control, as well as BACNET connectivity. The LRC2410 is a compact, self-contained lighting controller providing flexible time schedule control and override for 8 lighting circuits. The standard relays are rated to directly switch 20A lighting loads eliminating the need for external contactors, relays and time clocks. Standard low voltage override switches, motion sensors, and an analog photocell may be assigned to control the relays via simple programming.
