What is the network recovery time for the EDS-528E in a redundant ring topology?

The EDS-528E achieves recovery times under 20 milliseconds at 250 switches using Turbo Ring technology. This sub-20ms failover ensures minimal data loss and maintains synchronization in real-time industrial control applications. Standard RSTP/STP provides additional redundancy options for different network topologies.

Can the EDS-528E operate in extreme temperature environments without additional cooling?

Yes. The wide-temperature model operates from -40 to 75°C without requiring environmental controls. The metal IP30 housing provides protection against dust and moisture. This makes it suitable for outdoor installations, unheated facilities, and high-temperature industrial environments like foundries and furnace areas.

What power input options are available for the EDS-528E?

Two models are offered: EDS-528E-4GTXSFP-LV supports 12/24/48/-48 VDC with redundant dual inputs (9.6-60 VDC operating range), while EDS-528E-4GTXSFP-HV supports 110/220 VAC/VDC with single input (88-300 VDC or 85-264 VAC operating range). The LV model provides redundancy; the HV model accommodates standard industrial AC/DC power infrastructure.

Does the EDS-528E support industrial automation protocols?

Yes. The switch natively supports EtherNet/IP, PROFINET, and Modbus TCP for device management and monitoring. It also supports DHCP Option 82 for IP address assignment with different policies. This eliminates the need for protocol gateways and simplifies integration with existing factory automation and process control systems.

What security features does the EDS-528E provide for critical infrastructure?

Security features include RADIUS, TACACS+, MAB Authentication, SNMPv3, IEEE 802.1X, MAC ACL, HTTPS, SSH, and sticky MAC-addresses. The switch is designed to IEC 62443 security standards for industrial control systems. These multi-layer protections prevent unauthorized access and meet compliance requirements for oil/gas, maritime, and utility applications.

What are the physical dimensions and mounting options?

The EDS-528E measures 115.4 x 135 x 137 mm (4.54 x 5.31 x 5.39 inches) and weighs 1850g (4.08 lbs). It supports DIN-rail mounting as standard and wall mounting with an optional kit. The compact form factor fits space-constrained industrial cabinets while maintaining full 28-port capacity.

Can the EDS-528E use fiber-optic connections for backbone networks?

Yes. The four combo Gigabit ports include built-in SFP slots for fiber-optic communication. This enables long-distance backbone connections while maintaining the compact DIN-rail form factor. Fiber connections reduce electromagnetic interference and support extended network distances in industrial environments.

Product overview

The Moxa EDS-528E is a compact 28-port Layer 2 managed Ethernet switch designed for harsh industrial environments. It features 24 Fast Ethernet (10/100 Mbps) ports and 4 combo Gigabit ports supporting RJ45 or SFP fiber connections. The switch delivers network redundancy through Turbo Ring, Turbo Chain (recovery <20ms at 250 switches), RSTP/STP, and MSTP protocols. Security is enhanced via RADIUS, TACACS+, SNMPv3, IEEE 802.1X, MAC ACL, HTTPS, and SSH. It supports EtherNet/IP, PROFINET, and Modbus TCP for device management. Available in low-voltage (12/24/48/-48 VDC) and high-voltage (110/220 VAC/VDC) models with operating temperatures from -40 to 75°C. The metal housing provides IP30 protection with DIN-rail and wall-mount options, making it ideal for maritime, rail, oil/gas, and factory automation applications.
