The RS-408 is a 8-Port Industrial Ethernet (10/100Base-TX) Real-Time Redundant Ring Switch.

RS-408 supports 10/100M auto-negotiation feature and auto MDI /MDIX function. It can automatically switches the transmission speed (10 Mbps or 100 Mbps) for corresponding connections. The connectors of Ethernet port are shielded RJ-45. The shielded RJ-45 connectors offer a high reliability Ethernet environment for industrial control and automation.

RS-408 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 300ms – 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-408 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-408's power needs. And, the relay output facility can deliver warning signal while dual power or network link failure.
