The EDS-405A-PTP is a robust, entry-level managed Ethernet switch designed for industrial applications requiring precise time synchronization. Equipped with 5 10/100BaseT(X) RJ45 ports, this switch supports hardware-based IEEE 1588v2 Precision Time Protocol (PTP), making it ideal for real-time automation, power substation systems, and transportation networks.

With support for advanced redundancy protocols such as Turbo Ring, Turbo Chain, STP, and RSTP, the switch ensures minimal downtime (<20 ms recovery with up to 250 switches). Network administrators can manage the switch via web interface, CLI, Telnet, or SNMP, and it supports industrial Ethernet protocols like EtherNet/IP and Modbus TCP. Enhanced security features include HTTPS, SSH, SNMPv3, and access control. Certified for harsh environments, the EDS-405A-PTP is built in a rugged metal housing with IP30 protection and delivers long-term reliability with an MTBF of over 1.3 million hours.
