Overview
IEC 62974-1:2017 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies product and performance requirements for monitoring and measuring devices. These devices are essential for data collection, gathering, and analysis in industrial, commercial, and similar applications. The standard targets devices rated up to 1 kV AC and 1.5 kV DC, intended for fixed indoor installation, typically panel-mounted or mounted on DIN rails inside cabinets.
The focus of IEC 62974-1:2017 is on devices that support energy efficiency by uploading or downloading key data such as energy consumption on loads, power metering, monitoring, and temperature information. Devices covered include energy servers, energy data loggers, data gateways, and I/O data concentrators.
This standard outlines critical safety, environmental, and performance criteria, ensuring that monitoring systems deliver reliable, accurate, and safe data acquisition for optimizing energy consumption and operational efficiency.
