Description
This Harmony RM22-LG relay allows monitoring of liquid level control in 3-phase networks. This modular multi function 3-phase liquid level control relay is ideal for monitoring of electrical values in industrial and building control panels. It applies to a wide type of industrial automation applications such as hoisting, packaging, lifts, textile, water. It has one of market slim form-factors with 22.5mm width, allowing for a flexible and easy installation on DIN rail, using the same space as any modular 1-pole DIN device. It also offers a diagnostic button, sealable cover, simple and precise settings with screw trimmers. It provides automatic shutdown management and fault information to user for a quick fault identification and troubleshooting. multi function controller for wide choice selected in hard-wired logic automated systems, ideal for refurbishment of old installations without using a PLC. 0 0 0 0 0 0 0 0 0 0 0 0
Features
- This highly versatile level monitoring relay features configurable "Fill" and "Empty" logic built right into its core firmware. This allows industrial control engineers to use a single piece of hardware to manage automated tank replenishment or prevent sump overflow basins from flooding, standardizing inventory while providing flexible utility across the entire plant.
- Equipped with an adjustable sensitivity potentiometer spanning from 5 kOhm to 100 kOhm, this relay adapts flawlessly to a wide variety of conductive media. Whether you are monitoring treated drinking water, municipal wastewater, or dense industrial chemical solutions, you can fine-tune the detection threshold to eliminate false triggers caused by high line resistance or scaling on the probes.
- Featuring a highly optimized, modular width of just 22.5mm, this device matches the physical profile of a standard 1-pole miniature circuit breaker. It integrates cleanly into crowded electrical control enclosures and distribution panels, maximizing your remaining rail space and preventing the need to upgrade to a larger, more costly enclosure layout.
- Built with integrated front-panel LED indicators and a diagnostic test button, this relay provides instant, visual verification of power status and relay contact output states for rapid on-site troubleshooting. A clear, sealable protective cover swings over the screw trimmers to completely block unauthorized field changes or accidental knob adjustments, maintaining your precise system parameters over long-term production runs.
