Description
The RSM-405FT series is a range of real-time redundant ring switches from ICPDAS. The RS-405FT is a Redundant Ring Switch which has 3 Ethernet Ports (10/100 Base-T ) with 2 Fibre Optic Ports (100 Base-FX, ST Connector).
They can be used for several different applications including:
- Link-lose-backup in the industrial field application. The ring topology quickly provides an alternative path should a network node or cable segment fail.
- A cost effective redundant ring Ethernet LAN can be configured by mixing RS-405FT with other low cost unmanaged Ethernet Switches such as the NS-205/208 series
- Ring Coupling : To join seperate ethernet rings together (such as over different floors or buildings).
Key features are:
- The RS-405FT series are equipped with 2 power inputs, which are redundant of each other.
- The relay output facility can deliver a warning signal on power or link failure
- Modbus/TCP protocol Supported : This allows the administrator of an Ethernet LAN, through SCADA software, to obtain information regarding the condition and individual port status of the RS-405FT.
This unit is supplied in an IP20 rugged, high-strength steel case capable of either DIN-Rail or Wall Mounting.
