Ang serye ng GRB8 ay isang kontrol na modyul na awtomatikong pumapalit sa pagbukas at sarado ng mga circuit batay sa intensidad ng liwanag sa kapaligiran. Sa pamamagitan ng paggamit ng isang built-in na precision photosensitive sensor upang detekton ang kahelihan ng kapaligiran, maaaring ma-trigger nang awtomatiko ang aksyon ng relay sa ilalim ng isang itinakdang threshold, na malawakang nauugnay 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".
Pagsusunod ng produkto ng optical control relay ng serye ng GRB8:
1. Intelligent public lighting
Malawakang ginagamit sa mga sistema ng ilaw 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 cost ng operasyon at maintenance.
2. Outdoor equipment light sensing start stop
Awtomatikong kontrolin ang mga outdoor lighting facilities tulad ng street lights, courtyard lights, at landscape light strips, synchronize ang timed opening at closing ng advertising light boxes at neon signs, paunlarin ang komersyal na imahe, at optimize ang energy consumption.
3. Security linkage system
Sumunod sa monitoring equipment, electronic fences, at iba pang security devices upang awtomatikong i-activate ang operasyon ng equipment sa madilim na kapaligiran sa gabi, na nagpapalakas ng seguridad ng venue.
4. Agricultural environmental regulation
Inilapat sa greenhouse lighting systems, livestock at poultry breeding lighting, at iba pa, na intelligently adjusts ang artificial light sources batay sa natural light intensity upang tumulong sa precision agricultural production.
5. Equipment automation
Sakto para sa vending machine displays, traffic signs, photovoltaic energy storage devices, at iba pa na nangangailangan ng day night mode switching, na nagpapahintulot ng efficient energy utilization.
Mga adhika ng produkto ng optical control relay ng serye ng GRB8:
