Automated Water Level Control: Nagmamantala ng optimal na antas ng tubig sa pamamagitan ng pagsisimula at pagtigil ng pump batay sa naka-preset na minimum at maximum na threshold.
Pump Protection: Adjustable sensitivity (5kΩ hanggang 100kΩ) nagpapahintulot ng pag-iwas sa dry-running sa pamamagitan ng pag-detect 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 kailangan.
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 ay 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 ginagawing madali ang pag-install.
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 na relay na ito ay nag-aalamin ng consistent water supply sa pamamagitan ng automatic na pag-control ng water pumps batay sa real-time level data. Kung ikaw ay nag-manage ng isang 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.
