LC3XLC3X Controller
Lighting Controller
The LC3X automatically switches three dry contacts in response to changes in natural daylight, utilizing
independent setpoints. The LC3X controller requires a separate PD style sensor and optional 3X/PD adapter to complete the low voltage system. The LC3X can be configured as a stand-alone controller, or for cascaded operation, with a master LC3X providing the sensor signals to slave controllers.

Options include the 3X/PD Photodiode adapter; which provides the sensor’s gain calibration, the 3X/T Timer which has multiple time ranges and selection of interval or additive functions, and the PD Simulator which is used to verify voltages of footcandle levels.
