Dold Liquid Level Relay DIN Rail Mount 24V DC Input 4A Current Rating MK9151.11 2-450kOhm DC24V

Dold MK9151.11 2-450kOhm DC24V Liquid Level Relay is a DIN Rail mount device designed for precise level monitoring and control of conductive liquids and powders. Operating on a 24V DC input voltage and rated for 4A relay output, it is suitable for various industrial and commercial applications including wastewater management, pump protection, and media mixing control.

This relay supports maximum and minimum level detection, protecting equipment from overfilling and dry running by monitoring liquid or powder fill levels effectively. The relay uses a galvanically isolated metering circuit that provides immunity against high interference, ensuring stable and accurate operation.

With a wide resistance setting range between 2 to 450 kilo-ohms, the device differentiates reliably between liquid and foam conditions. It features adjustable response and fallback delays from 0.2 to 20 seconds, customizable to specific application requirements.

The compact design mounts on standard DIN rails with overall dimensions of 82mm length, 22.5mm width, and 99mm depth, making it suitable for dense control panel installations. Terminal connections are clamp type for secure wiring, and the device holds an IP20 protection rating.

Additional features include 3 electrode connections allowing for 1-point or 2-point level control, 2 LEDs indicating power and contact status, and programmability for working or rest current principles. It operates reliably within a temperature range of -20 to 60 degrees Celsius.
