The RS-405 series is a 5-Port Industrial Ethernet (10/100Base-TX) Real-Time Redundant Ring Switch. RS-405 series supports 10/100M auto-negotiation feature and auto MDI /MDIX function. It can automatically switch 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.
Built-in ICP DAS Cyber-Ring technique that enable multiple switches to be placed into a redundant ring. Typically it detects and recovers from a copper link failure within approximately 20 ms – for the majority of applications a seamless process. The RS-405 series is much more easy to use and absolutely free of software setting. After unpacking from the shipping case, it just takes one or two dip or rotary switch to make it work.
The RS-405 series 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-405 series 's power needs. And, the relay output facility can deliver warning signal while dual power or network link failure.
