The ICP DAS RSM-405FC is a 5-port industrial Ethernet (10/100Base-TX) real-time redundant ring switch with 2-Fibre ports. The RSM-405FC 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 which offers a high reliability Ethernet environment for industrial control and automation. The Built-in ICP DAS Cyber-Ring technique enables multiple switches to be set-up into a redundant ring. This redundant switch typically detects and recovers from a copper link failure within approximately 20 ms. The ICP DAS RSM-405FC is easy to use with minimal software settings. The RSM-405 provides two power inputs that can be connected simultaneously to DC power sources. If one of the power inputs fails, the other live source acts as a backup to automatically support the RSM-405FC’s power needs. The RSM-405FC is also equipped with a relay output which delivers warning signal if there’s a dual power or network link failure.
