RUGGEDCOM RS940G

The RUGGEDCOM RS940G is a utility-grade, fully managed Ethernet switch, providing six or eight ports of Gigabit Ethernet. Six 10/100/1000BaseTX triple speed copper ports are standard. An additional two Gigabit fiber or copper ports can be added. The RS940G provides a cost effective way of connecting a cluster of field devices to a Gigabit Ethernet backbone. The RS940G provides two fiber optical Gigabit Ethernet ports for creating a fiber optical backbone with high noise immunity and long haul connectivity.

Managed Ethernet switch with fiber optic uplinks and 128-bit encryption
