Liquid Level Relay HHY2 Series

MOQ : 100

The C-LIN Liquid Level Control Relay (HHY2 Series) provides a professional floatless level switch solution for precise automatic water level management. This versatile pump control relay is available in two specialized working modes: the HHY2P for drainage (emptying) and the HHY2G for water supply (tank filling). Engineered for large-scale industrial use, it supports long-distance water control of up to 500 meters. Compatible with multiple industrial power supplies (DC24V, AC24V, AC220V, AC380V), the unit features a reliable 3A NO/NC contact in a compact 40×55×79mm housing. With flexible mounting accessories, it easily integrates into 35mm DIN rail, panel, or device-based systems, ensuring maximum automation efficiency.

The C-LIN HHY2 Series operates as an intelligent electrode level controller designed for high-performance water level sensing and automated fluid management. This wide-voltage level sensor supports a vast array of power inputs from DC24V to AC380V, facilitating remote fluid monitoring at distances reaching 500 meters. Optimized for reliability, the HHY2G supply model and HHY2P drainage model feature a socket-base design for rapid integration into sump pump control systems. Encased in a compact 40×55×79mm frame, it provides a 3A NO/NC contact and versatile panel-mount or DIN rail installation, ensuring peak operational safety for industrial tanks and reservoirs.
