The mid-range, 8-port Unmanaged 852-103 and range-topping 7-port Managed 852-104 Switches support networks in harsh applications.
The unmanaged 852-103 Ethernet Switch features a redundant power supply and a 9V-48V supply voltage range. A top-mounted DIP Switch sets an alarm relay to monitor loss of 24 VDC or port status (selectable by port). Beyond eight 100BASE-TX ports for copper connections, 852-103 provides two 100BASE-FX SFP ports for fiber optic cables.
Building on the 852-103’s features, the 7-port 852-104 Managed Ethernet Switch provides Xpress Ring and Jet Ring networking features. Xpress ringenables networks to recover from link failure within 50ms; Jet Ring provides redundant data-transmission routes during link failure/damage – recovery occurs in less than 300ms. In addition, 852-104 provides Web-based management, port configuration and data packet prioritization. IGMP snooping and management access (security) are also offered. In addition to seven 100BASE-TX ports (copper), 852-104 carries two 100BASE-FX SFP ports (fiber optics).
Both feature a robust, IP30 metal housing, anti-shock/vibration proprieties and overvoltage/polarity protection. Approvals include CE, UL and UL 508.
