Modernization of drinking water infrastructure: equipment for Eau du Grand Lyon

As part of the modernization of its drinking water stations, Eaux du Grand Lyon recently called on SOC and JM Concept to optimize the management and safety of its facilities.

The objective? 

To enhance the reliability of measurements while ensuring the galvanic isolation of signals from its field sensors. To achieve this, the teams deployed the JK2001-F, a self-powered galvanic isolator designed and manufactured by JM Concept.

A need for reliability and safety for analog measurements

Greater Lyon's drinking water stations are critical facilities, where measurement quality and equipment robustness are essential. The need focused on two types of sensors commonly used in instrumentation:

• A flow meter, responsible for continuously measuring the flow of water entering or leaving the station.
• A level sensor, used to monitor the volume of water in the reservoirs.

These sensors deliver analog signals that must be isolated and protected before being processed by the supervisory controllers. It is in this context that the JK2001-F, a high-precision galvanic isolator, was integrated.

The JK2001-F: a self-powered, robust, and accurate galvanic isolator

The JK2001-F is an electrical signal conditioning device designed to galvanically isolate measurement loops. It offers several key advantages for water network operators:

• Self-powered: the JK2001-F operates without an external power supply, simplifying installation and reducing cabling costs.
• High-performance isolation: it guarantees reliable separation of analog channels to avoid any risk of interference or short circuits.
• Surge protection option (-F): in exposed environments, this additional protection ensures signal durability even in the event of power surges.
• Compact and simple: its DIN rail format and ease of connection make it a valuable ally for integrators.

Thanks to this solution, data from the field is transmitted securely and accurately, ensuring optimal operation of the installations. 

A successful project with SOC and Eaux du Grand Lyon

This application perfectly illustrates JM Concept's expertise in industrial automation and instrumentation in the water sector. In collaboration with SOC, the project's technical integrator, the teams were able to offer a reliable solution adapted to the environmental and technical requirements of drinking water stations.

We would like to warmly thank Eau du Grand Lyon for their trust and our partners for their commitment to this project.
