Product Description

The ABB 1SVR730850R0100 CM-ENS.11S is a high-quality liquid level relay engineered for monitoring and controlling the levels of conductive liquids in various industrial and utility applications. This relay gives accurate protection from both overfill and dry running scenarios, safeguarding pumps and liquid management systems and helping to minimize manual intervention and maintenance.

This model is designed for DIN rail mounting, ensuring easy integration into modern equipment and control cabinets. With a compact 22.5mm width, the relay conserves valuable panel space while maintaining robust performance characteristics. Its flame-retardant housing and IP20 (terminal) and IP50 (enclosure) ratings provide added safety and resilience against dust and fire hazards.

The 1SVR730850R0100 CM-ENS.11S relay operates with a wide voltage supply of up to 240V AC or DC, offering installation flexibility across regions and machine designs. A key feature is its adjustable measurement sensitivity, ranging from 5 to 100kΩ, making it suitable for a broad range of conductive liquids and tank configurations. The single-pole double-throw (SPDT) output relay contact supports efficient interface to alarms and process controls.

For easy status monitoring, the unit is equipped with three front-panel LEDs, promptly displaying relay activity, supply, and liquid status. The device has a screw terminal connection for reliable wiring and supports current ratings up to 11mA. It operates efficiently in ambient temperatures from -25°C to 60°C, ensuring reliable service in industrial environments such as breweries, utility systems, wastewater plants, process tanks, and pharmaceutical installations.

The unit meets global safety and EMC conformity standards, including CAN/CSA C22.2 No.14, IEC/EN 60255-27, IEC/EN 60947-5-1, IEC/EN 61000-6-2, IEC/EN 61000-6-3, and UL 508. It ensures peace of mind for installation in certified facilities. Typical use cases for this relay include: liquid level control in process tanks, pump protection against dry running, monitoring both minimum and maximum levels, and involvement in mixing and leak-detection systems.

Applications span water and wastewater management, heater treaters, breweries, the pharmaceutical sector, and any industry requiring safe and efficient monitoring of conductive liquids. Its operational reliability and compact design make it a powerful choice for new installations and retrofits alike.
