Ang serye ng GRB8 ay isang kontrol na modulyo na awtomatikong nagsasakatuparan at nagsasara ng mga circuit batay sa lakas ng liwanag sa kapaligiran. Sa pamamagitan ng paggamit ng built-in na precision photosensitive sensor upang detektoin ang katalulan ng kapaligirang liwanag, maaaring awtomatikong ma-trigger ang aksyon ng relay sa ilalim ng itinakdang threshold, na malawakang aplikable sa electrical equipment na nangangailangan ng linkage control ng kondisyon ng liwanag, na nagpapatupad ng intelligent operation ng "start at dark and stop at dawn".
Application ng optical control relay products ng serye ng GRB8:
1. Intelligent public lighting
Malawakang ginagamit sa lighting systems para sa mga pampublikong lugar tulad ng residential corridors, underground garages, at factory passages, na nagpapahintulot ng energy-saving control ng "lights on when people come, lights off when people leave" at nagbabawas ng operational at maintenance costs.
2. Outdoor equipment light sensing start stop
Awtomatikong kontrolin ang outdoor lighting facilities tulad ng street lights, courtyard lights, at landscape light strips, sumynchronize ang timed opening at closing ng advertising light boxes at neon signs, palakasin ang commercial image, at optimize ang energy consumption.
3. Security linkage system
Sumama sa monitoring equipment, electronic fences, at iba pang security devices upang awtomatikong i-activate ang operasyon ng equipment sa low light environments sa gabi, palakasin ang seguridad ng venue.
4. Agricultural environmental regulation
Ipinapakilala sa greenhouse lighting systems, livestock at poultry breeding lighting, atbp., na intelligently adjust ang artificial light sources batay sa natural light intensity upang tumulong sa precision agricultural production.
5. Equipment automation
Sapat para sa vending machine displays, traffic signs, photovoltaic energy storage devices, atbp. na nangangailangan ng day night mode switching, na nagpapatupad ng efficient energy utilization.
Mga advantage ng optical control relay products ng serye ng GRB8:
1. Environment adaptive: Built-in na high-sensitivity photosensitive element, accurately responding sa natural lighting changes
2. Flexible regulation: supports seamless switching between manual at automatic modes upang matugunan ang diverse control needs
3. Space friendly: ultra-thin body design, saving electrical installation space
4. Safe at reliable: Compliant sa mainstream electrical standards, compatible sa globally applicable voltages
5. Status visualization: intuitive LED indication, real-time monitoring ng equipment operation status
