Foreword
Overview of the e-light 2MA product family
The devices in the e-light 2MA product family are industrial Ethernet switches including
management features that can be configured comfortably and easily via a web application. These
enable low-cost installation of industrial Ethernet bus, star, and ring structures with switching
functionality.
In addition to the basic version of the e-light 2MA, which is delivered without fiberoptic connections,
there are versions with two or four fiberoptic connections. These devices can be equipped with the
most diverse transceivers for single mode or multi-mode featuring plug connector types ST or SC.
