Fast, safe integration of Ex i isolators

| By Mary Page Bailey and Gerald Ondrey

The pac-Carrier 9295 (photo) is a new, space-saving integration solution for this company’s 12-mm ISpac Ex i isolators. This significantly simplifies the installation and wiring of isolators to input/output (I/O) cards in automation systems from all manufacturers. Prefabricated connecting cables reduce the risk of wiring errors. Furthermore, the installation time is reduced by up to 40% thanks to the isolators’ tool-free mounting, says the company. This integration solution is particularly suited for projects involving a high number of channels. The new pac-Carriers are available in 8- and 16-slot versions, thereby enabling up to 32 signals to be connected. The variant with eight slots is only 110 mm wide. An additional HART multiplexer coupling only requires 36 mm of extra space. ISpac devices and the pac-Carriers are approved for use in Zone 2 decentralized installations. The pac-Carrier can also be used for functional safety applications up to safety integrity level (SIL 3). — R. Stahl AG, Waldenburg, Germany
