The RS-405FT is a 5-Port Industrial Ethernet Real-Time Redundant Ring Switch with 2-Port Fiber (ST Connector; Multi-mode) that secures data transmission by using fiber optics transmission to provide immunity from EMI/RFI interference. It is used Ethernet for transmitting a signal up to 2 Km(6,600 ft), and is the perfect solution for applications where transmission must be protected from electrical exposure, surges, lightning or chemical corrosion.

Fiber port of RS-405FT operates at either half or full duplex mode. In full duplex mode, range is 2km with 62.5/ 125μm fiber cables; in half duplex mode, range is 412m with 62.5/ 125μm fiber cables. The Ethernet port of RS-405FT supports 10/ 100M auto-negotiation feature and auto MDI /MDIX function.

Built-in ICP DAS Cyber-Ring technique that enable multiple switches to be placed into a redundant ring. It detects and recovers from a fiber or copper link failure within approximately 50ms – for the majority of applications a seamless process. Modbus/TCP, Modbus/RTU and OPC supported, SCADA application can monitor status of Ethernet and fiber port with Modbus or OPC protocol.

RS-405FT provides two power inputs that can be connected simultaneously to live DC power sources. If one of the power inputs fails, the other live source acts as a backup to automatically support the RS-405FT's power needs. And, the relay output facility can deliver warning signal while dual power or network link failure.
