Hot swap of fieldbus barriers in explosive atmospheres

The Stahl miniClix Ex plug connector system now features Y adapters that enable users to quickly route two cables to one plug or socket with hot swap functionality in Zone 1 areas. The concept of fieldbus barriers, has proven to be the most powerful solution for fieldbus installations in explosive atmospheres. A non-intrinsically safe trunk provides enough energy to power a maximum of 16 intrinsically safe / Fisco field devices per segment.

Type 8592 miniClix Y adapters are certified for hot swap of non-intrinsically safe signal lines. Using miniClix connectors and Y adapters at the trunk connection of a fieldbus barrier, each barrier can be safely unplugged during operation in explosive atmospheres, without interrupting the whole segment. No special hot work permit is needed. This solution combines the effectiveness of the power trunk principle with the hot swap convenience of intrinsic safety. MiniClix connectors also allows for converting Ex d field devices into “plug and play” versions, making all fieldbus devices hot swappable.
