Industrial Ethernet Solutions

The EDS-505A/508A/516A are standalone 5, 8, and 16-port managed 
Ethernet switches. With their advanced Turbo Ring and Turbo Chain 
technology (recovery time < 20 ms), RSTP/STP, and MSTP support the 
EDS-505A/508A/516A switches increase the reliability and availability 
of your industrial Ethernet network. Models with an wide operating 

•  Command Line Interface (CLI) for quickly configuring major 

managed functions

•  IPv6 Ready logo awarded (IPv6 Logo Committee certified)

•  IEEE 1588 PTP V2 (Precision Time Protocol) for precise time 

synchronization of networks

•  DHCP Option 82 for IP address assignment with different policies

•  Support EtherNet/IP and Modbus/TCP protocols for device 

management and monitoring

•  Compatible with EtherNet/IP and PROFINET protocols for 

transparent data transmission

•  Turbo Ring and Turbo Chain (recovery time < 20 ms @ 250 

switches), RSTP/STP, and MSTP for network redundancy

•  IGMP snooping and GMRP for filtering multicast traffic

temperature range of -40 to 75°C are also available, and the switches 
support advanced management and security features, making the 
EDS-505A/508A/516A switches suitable for any harsh industrial 
environment.

•  Port-based VLAN, IEEE 802.1Q VLAN, and GVRP to ease network 

planning

•  QoS (IEEE 802.1p/1Q) and TOS/DiffServ to increase determinism

•  Port Trunking for optimum bandwidth utilization

•  RMON for efficient network monitoring and proactive capability

•  SNMPv1/v2c/v3 for different levels of network management

•  TACACS+, SNMPv3, IEEE 802.1X, HTTPS, and SSH to enhance 

network security

•  Bandwidth management to prevent unpredictable network status

•  Lock port function for blocking unauthorized access based on MAC 

address

•  Automatic warning by exception through e-mail, relay output
