JL-428 Conduit Wire-In Digital Photocontrol Overview:

The JL-428 series of photocontrols is suitable for automatically regulating lighting in passageways and doorways, responding to the ambient light levels. These devices feature electronic circuits with an integrated microcontroller unit (MCU). Their rapid response, coupled with a 5-second time delay, facilitates easy testing while preventing unnecessary activation from vehicle headlights or lightning at night. Additionally, the series is equipped for midnight shutdown and pre-dawn reactivation. The optional Z model includes zero-crossing technology for increased longevity and meets FCC compliance. Moreover, the JL-428 series offers surge protection up to 235J/5000A.
