The MRX Series is an ATEX approved reed relay according to KIWA 19ATEX0051 U and IECEx KIWA 19.0026U and is used for the galvanic separation of intrinsic safety and non-intrinsic safety circuits in hazardous locations. The MRX ATEX & IECEx approved reed relays are suitable for circuits of the protection method “ia” (intrinsic safety) up to the Zone 0 in the gas and vaporous atmosphere. It is designed for the temperature range -40°C to +85°C and for the peak voltage up to 375 VDC and 50 Watt. Switching configuration is 1 – 4 Form A or 2 Form C switches.
Type of protection: II (1) G [Ex ia Ga] IIC
