EDS-508A Series

Introduction
The EDS-508A standalone 8-port managed Ethernet switches, with their advanced Turbo Ring and Turbo Chain technologies (recovery time < 20 ms), RSTP/STP, and MSTP, 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 advanced management and security features, making the EDS-508A switches suitable for any harsh industrial environment.

Additional Features and Benefits

Command line interface (CLI) for quickly configuring major managed functions
DHCP Option 82 for IP address assignment with different policies
Supports EtherNet/IP and Modbus TCP protocols for device management and monitoring
Compatible with PROFINET protocol for transparent data transmission
Automatic warning by exception through email and relay output
IGMP snooping and GMRP for filtering multicast traffic
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 proactive and efficient network monitoring
SNMPv1/v2c/v3 for different levels of network management
Bandwidth management to prevent unpredictable network status
Lock port function for blocking unauthorized access based on MAC address
