Redundante Ring-Switches

The RS-405 CR is a five-port industrial Ethernet switch built for real-time redundant ring networks. Each RJ-45 port negotiates 10 or 100 Mbps automatically and adapts to crossover or straight-through cabling, so it can be installed without software configuration. Ring redundancy is handled by the built-in ICP DAS Cyber-Ring technique, which can recover from a copper link failure in approximately 20 ms.Store-and-forward switching, 2048 MAC addresses and 1 Mbit of frame buffer memory support stable operation in busy control networks. Two isolated DC inputs (+10 ~ +30 VDC) can be connected to live sources at the same time, so the unit keeps running if one supply fails. A relay output signals dual-power or network link failures to the control system.Settings are made with DIP switches for redundancy mode and maximum recovery time. The plastic DIN-rail housing measures 65 x 120 x 99 mm and operates from -40 °C to +75 °C. This model is RoHS compliant.ApplicationsIndustrial control and automation networksRedundant Ethernet ring topologies
