Global energy management specialists Schneider Electric announced at its Xperience Efficiency event in Johannesburg, which took place last month, that the new range of Zelio temperature controllers and accessories is now available to the South African market. These key components are used for temperature regulation in heating and refrigeration applications.

The cost-effective Zelio RTC48 temperature controllers combine simplicity, performance and value, and have the ability to interface with solid-state relays, electromechanical relays, programmable logic controllers and human-machine interface displays.

Temperature controllers are designed to automatically compare the process value (PV) with its set value (SV) and produce an output that will maintain the SV. Temperature controllers are deployed at multiple points in the manufacturing process to enable the execution of critical processes, such as the creation of highly complex recipes in the food and beverage industry or the exact temperature control in packaging machines.

The Zelio RTC48 offer comprises a standard 48 mm x 48 mm format and provides the best balance between price and functionality, featuring the desirable proportional-integral-derivative control with auto-tuning, communication, outputs and alarms.

“Many industries desire simple and cost-effective temperature controllers to regulate the temperatures in their processes to ensure that the best-quality products are achieved. The Zelio RTC48 temperature controllers provide a well-designed solution to meet this need. Our years of expertise in research, design and manufacturing have enabled us to deliver exceptional value to our customers. We continuously strive to ensure the ease-of-use, ruggedness and reliability of our temperature controllers in our customers’ processes,” says Schneider Electric relays business director Didier Baron.

The Zelio RTC48 is easy to set up and the free-to-download configuration software further simplifies the set-up through a universal serial bus to personal computer connection. The front panel has an intelligent PV status display that actively analyses the measured PV relative to the SV and changes the display colour accordingly. The overall compact design is only 56 mm in depth and this translates to reduction in panel sizes.
