New media for Ex-Zone 1

31 March 2008

Ethernet is going into Ex Zone 1 thanks to new fibre optic modules for Hirschmann’s DIN-rail mounted MICE switches.

The module has four optical ports (100 Mbit/s) with M12 connections; signals are transmitted from the module to the remote terminals via fiber optic cables. MicroFX transceivers with M12 connectors serve as an Ethernet interface.

The remote terminal may therefore easily get the necessary approval for explosive zone 1 atmospheres.

Hirschmann’s MICE family supports Fast and Gigabit Ethernet and various routing, redundancy and security methods, and is already approved for installation in explosion protection zone 2.
