The tests were conducted in the Eurofins laboratories in Germany and comprised different sessions where the relays were exposed to corrosive substances (sulphur dioxide SO2, hydrogen sulphide H2S) and compounds (H2S+NO2+Cl2+SO2) for 21 days, as per IEC 60068 and ANSI/ISA S71.04 class G3.
The known reliability of the Relion® 670 and 650 series will now be available even in harsh environments, making the relays very suitable for oil & gas industry and windfarm platforms.
