The EDS-4009 Series delivers compact, reliable Layer 2 switching for industrial backbones and edge cabinets. Each model provides six 10/100Base-T(X) copper ports plus up to three 100Base-FX fibre ports, with options for multi-mode ST/SC or single-mode SC to reach longer distances. Built-in redundancy includes Turbo Ring and Turbo Chain with recovery under 20 ms across 250 switches, alongside RSTP/STP, MSTP, MRP, dual-homing and link aggregation (LACP) to maintain availability during faults.
Security and manageability are first class. The series is IEC 62443-4-2 Security Level 2 certified, and supports role-based access, SSH/HTTPS, 802.1X, ACLs, DHCP snooping, storm control and MAC protections. MXstudio integration streamlines visualised network setup and diagnostics, while SNMPv1/v2c/v3, LLDP, RMON, syslog, email/SNMP traps, port mirroring (SPAN/RSPAN) and fibre check simplify operations. Industrial protocol support covers EtherNet/IP, Modbus TCP and PROFINET Device. Time-sync is handled by hardware-based IEEE 1588v2 PTP with utility and substation profiles (IEC 61850-9-3, IEEE C37.238).
Switch resources include a 16K MAC table, 1 MB packet buffer, 9,216-byte jumbo frames, four QoS queues, VLAN tagging (up to 256 VLANs), IGMP snooping/querier and rate limiting. A front-panel alarm relay and digital input enable panel or PLC integration. Power is modular: LV models offer redundant 12/24/48 VDC inputs (9.6–60 VDC), while HV models accept a single 110/220 VDC/VAC input (88–300 VDC, 85–264 VAC).
The IP40 metal housing (55 mm wide) supports DIN-rail or wall mounting. Standard models operate from -10 to 60°C; wide-temperature -T models operate from -40 to 75°C. Certifications include EN 50121-4 (railway), IEC 61850-3 / IEEE 1613 (substation), maritime approvals (selected LV models) and hazardous-location ratings (C1D2/ATEX/IECEx, selected LV models).
