Automated Water Level Control: Nagpapanatili ng optimal na antas ng tubig sa pamamagitan ng pagpapatakbo at pagtigil ng pump batay sa itakdang minimum at maximum na threshold.
Pump Protection: Adjustable sensitivity (5kΩ to 100kΩ) nagpapahintulot na maiwasan ang pagtakbo nang walang tubig sa pamamagitan ng pagdetect ng mababang antas ng tubig, na nagpapahaba ng buhay ng pump.
Manual Start Option: Ang external start button ay nagbibigay ng flexibility para sa manual na operasyon ng pump kapag kinakailangan.
Wide Voltage Compatibility: Galvanically separated supply voltage (AC/DC 24V-240V) nag-aalamin ang ligtas at versatile na operasyon.
Real-Time Monitoring: Green at red LED indicators nagbibigay ng malinaw na feedback sa relay status at water shortage alerts.
Space-Saving Design: Compact dimensions (18mm W x 64mm D x 90mm H) at DIN-rail mounting gawing madali ang installation.
Ang GRL8-03 liquid level control relay ay isang specialized device na inihanda para sa precise water level management sa mga aplikasyon tulad ng water towers, wells, at storage tanks. Ang compact, DIN-rail mountable relay na ito ay nag-aalamin ang consistent water supply sa pamamagitan ng automatic control ng water pumps batay sa real-time level data. Anuman ang iyong pinapamahalaan, kung industrial facility o residential water system, ang GRL8-03 ay nagbibigay ng advanced features tulad ng adjustable sensitivity, galvanically separated supply voltage, at pump protection upang magbigay ng reliable performance at operational efficiency.
