RS-405 series are ICPDAS’ latest real-time redundant ring switches.
They can satisfy the requirement for link-lose-backup in the industrial field applications:

Link-Loss-Backup:
The Backup path will become Active within 100ms (configurable),
and keep the whole LAN working




RS-405 series supports versatile topologies:

Versatile Topologies:
The proprietary STP protocol of RS-405 allows users to construct
more complicated topologies than basic ring architecture.




It is also possible to construct a cost effective redundant ring Ethernet LAN by mixing
RS-405 with other low cost unmanaged Ethernet Switch, the NS-205/208 series.

Cost Effective Ring Ethernet:
Having one RS-405 and other lower cost unmanaged Ethernet
switches (e.g. NS-205/208 series) in a ring, this Ethernet LAN
is also tolerant to link lose.





RS-405 series are equipped with 2 power inputs, which are redundant for each other.
The relay output facility can deliver warning signal during power failure or link loss.

Relay Output:
The relay output of RS-405 could deliver warning signal when
failure on one power input or when link lose.




With supporting Modbus/TCP protocol, the administrator of Ethernet LAN
can get the information of individual port status of RS-405.

Modbus/TCP:
RS-405 series supports Modbus/TCP protocol. Using this protocol,
administrator of Ethernet LAN can read port status of RS-405 and
SCADA can know the condition of the LAN it's based on.
