The EDS-4008-HV-T is a rugged managed Layer 2 Fast Ethernet switch engineered for industrial networks that need a compact form factor with serious reliability. It provides eight 10/100BaseTX RJ45 ports to mix local copper connections with long-distance Fibre or high-speed uplinks as required by the specific variant.
Certified to IEC 62443-4-1 and IEC 62443-4-2, it enables secure operation with VLAN segmentation, user authentication, access control, and event logging. Network resilience is delivered through Turbo Ring and Turbo Chain (sub-20 ms recovery under typical loads) alongside RSTP/STP for standards-based redundancy.
Powering is tailored for the environment: this model supports 88V to 300V DC or 85V to 264V AC Power Input, matching common control-panel and field-cabinet supplies without extra conversion hardware. The design uses an IP40 metal enclosure, fanless cooling, DIN-rail mounting, and status LEDs plus a fault relay output to simplify diagnostics and maintenance.
Operating temperature is rated for -25°C to 75°C, supporting dependable service in indoor control rooms, equipment racks, and sheltered industrial cabinets.
Management and monitoring are streamlined with MXstudio, LLDP, SNMPv1/v2c/v3, and a rich web/CLI interface, while features such as quality of service, IGMP Snooping/Querier, port trunking with LACP, and port mirroring help optimise deterministic traffic for control, video, and telemetry.
Typical applications include utility control rooms, heavy manufacturing, and transport infrastructure with high-voltage feeds. Whether deployed in brownfield upgrades or new builds, the EDS-4008-HV-T helps operators harden their OT networks with consistent security controls and fast recovery from faults, while keeping installation simple and predictable.
Connect control networks where 88V to 300V DC or 85V to 264V AC is available (no extra converters).
Hardened security features for mixed-vendor OT environments.
Direct mains/traction power compatibility reduces BOM and wiring.
Wide-temperature -40°C to +75°C for exposed cabinets.
Ideal for substations and switch rooms with high-voltage feeds.
Fast ring recovery helps maintain SCADA visibility during faults.
Straightforward retrofit into existing mains-powered enclosures.
Policy-driven segmentation to isolate cameras and access systems.
