Ido Water Level Daɗi: Yadda ake da shirin water mai yawa da kuma sauran pump based on preset minimum and maximum thresholds.
Pump Protection: Adjustable sensitivity (5kΩ to 100kΩ) prevents dry-running by detecting low water levels, extending pump lifespan.
Manual Start Option: External start button provides flexibility for manual pump operation when needed.
Wide Voltage Compatibility: Galvanically separated supply voltage (AC/DC 24V-240V) ensures safe and versatile operation.
Real-Time Monitoring: Green and red LED indicators offer clear feedback on relay status and water shortage alerts.
Space-Saving Design: Compact dimensions (18mm W x 64mm D x 90mm H) and DIN-rail mounting make installation a breeze.
The GRL8-03 liquid level control relay is a specialized device engineered for precise water level management in applications such as water towers, wells, and storage tanks. This compact, DIN-rail mountable relay ensures a consistent water supply by automatically controlling water pumps based on real-time level data. Whether you’re managing an industrial facility or a residential water system, the GRL8-03 offers advanced features like adjustable sensitivity, galvanically separated supply voltage, and pump protection to deliver reliable performance and operational efficiency.
