Wide temperature Ethernet switches
Two new Wago Ethernet switches operate in temperatures between -40 C to +70 C. Both the 852-103 and 852-104 are designed for process, energy, transportation and automation applications.
Wago's 852 Series Ethernet Switch family now features two Wide Temperature models for operation between -40 C to +70 C. The mid-range, 8-port Unmanaged 852-103 and range-topping 7-port Managed 852-104 Switches support networks in harsh process, energy, transportation and automation applications.
The Unmanaged 852-103 Ethernet Switch features a redundant power supply and a 9V–48 V supply voltage range. A top-mounted DIP Switch sets an alarm relay to monitor loss of 24 V dc 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.
The 7-port 852-104 Managed Ethernet Switch provides Xpress Ring and Jet Ring networking features. Xpress ring enables networks to recover from link failure within 50 ms; Jet Ring provides redundant data-transmission routes during link failure/damage — recovery occurs in less than 300 ms. 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 IP30 metal housing,anti-shock/vibration proprieties and overvoltage/polarity protection. Approvals include CE, UL and UL 508.
