Product Description

Dold IL9151.12 2- 50kOHM DC24V 0.2-20S Monitoring Relay is a High-Quality Level Monitoring Device suitable for Industrial and Automation applications requiring precise control of conductive liquids and powders. It operates with dual changeover contacts (2 CO) and is designed for DIN Rail mounting, providing easy integration into control panels.

This relay supports both 24 V DC and 230 V AC supply voltages, allowing broad compatibility with industrial power systems. Its time delay is adjustable from 0.2 to 20 seconds, separately programmable for minimum and maximum levels, ensuring flexible process control.

The galvanically isolated measuring circuit significantly reduces susceptibility to electrical interference and enables a maximum electrode lead length of 1500 meters. The relay complies with IEC 255 and VDE 0435 standards, facilitating reliable level detection using 1 or 2-point electrode connections.

Applications include monitoring maximum and minimum fill levels, protection against overfill and dry run conditions, control of mixing ratios in conductive liquids, and general resistance monitoring tasks such as temperature limit recording with PTC sensors. The device also features programmable operating or rest current principles for output relays and employs an internal AC voltage generation (~30 Hz) to avoid electrolysis effects on sensors.

Two separately operating changeover relays suitable for minimum and maximum level control. Flat terminal design for reliable and convenient wiring. Compact dimensions: 90 mm height, 59 mm length, 35 mm width. Rated IP40 and IP20 protection ensuring robustness in typical industrial environments.

CE and CCC compliance guarantee quality and safety standards. LED indicators provide visual feedback for operational readiness and contact position.

Commonly used in water treatment plants, chemical processing, and other manufacturing industries for level detection and control. This relay enhances operational safety by protecting pumps from dry running and enables precise liquid level management in various industrial scenarios.
