As this is a Unit Verification Certificate, no QAR is applicable as this certificate is specific to the items listed by serial number or other unique identification.
Subject and Type Fieldbus Barrier type R4D0-FB-IA* The Fieldbus Barrier is available in the following variants:R4D0-FB-IA8 8-channel R4D0-FB-IA10 10-channel R4D0-FB-IA12 12-channel Behind the number of channels, optionally further numbers or letters may be included in the type denomination to indicate different variations without influence on explosion protection. Description The 8-channel (R4D0-FB-IA8), 10-channel (R4D0-FB-IA10) and 12-channel (R4D0-FB-IA12) Fieldbus Barriers are galvanically isolated fieldbus couplers for the supply of intrinsically safe field devices and the bidirectional transmission of the fieldbus signals. The up to 12 outputs are intrinsically safe, with level of protection “Ex ia IIC” resp. “Ex ia IIIC”, and can be led in areas requiring category 1G resp. 1D. The intrinsically safe outputs are designed to be used in accordance with the Entity- and FISCO concept. On the trunk side the Fieldbus Barrier is supplied by a non-intrinsically safe circuit. The trunk connection for the supply is doubled to be able to loop through the supply voltage to the next unit. Maximum 3 Fieldbus Barriers may be connected to the trunk. The non-intrinsically safe circuits are protected by type of protection increased safety “Ex e” and encapsulation “Ex mb” and fulfill the requirements of category 2G. The Fieldbus Barrier is intended to be mounted into an enclosure type of protection increased safety resp. into a suitable, separately certified enclosure.
