The EDS-505A/508A are standalone 16-port managed Ethernet switches. With their advanced Turbo Ring and Turbo Chain technology (recovery time less than 20 ms) and RSTP/STP (IEEE 802.1w/D), the EDS-505A/508A switches increase the reliability and availability of your industrial Ethernet network. Models with a wide operating temperature range of -40 to 75°C are also available, and the switches support several reliable and intelligent functions, including IEEE 1588 PTP, Modbus/TCP, LLDP, SNMP Inform, QoS, IGMP snooping, VLAN, IEEE 802.1X, HTTPS, SNMPv3, and SSH, making the EDS-505A/508A switches suitable for any harsh industrial environment.
