Moxa EtherDevice Switch EDS-508A/505A Series

Lead time 4-22 days
Industrial 8- and 5-port Advanced Managed redundant Ethernet Switches.
Moxa EDS-508A/505A series is a plug-and-play managed redundant industrial Ethernet switch.

A set of Turbo Ring DIP switches makes it easy to set up Turbo Ring (recovery time increase system reliability.

In addition, Moxa EDS-508A/505A supports many advanced managed features, suchas QoS,
802.1Q VLAN, port-based VLAN, IEEE802.1X, SSL, SNMP V1/V2c/V3, IGMP Snooping,
Port Trunking, and RMON for network management.

Advanced Industrial Networking Capability

* Plug-n-Play, Turbo Ring (recovery time * IGMP Snooping and GMRP for filtering multicast traffic from industrial Ethernet
* Port-based VLAN, IEEE802.1Q VLAN and GVRP protocol to ease network planning
* QoS-IEEE802.1p/1Q and TOS/DiffServ to increase determinism
