Moxa EDS-2008-EL 8-Port Fast Ethernet Unmanaged Switch

What the EDS-2008-EL does on the plant network

A compact plug-and-play switch for machine cabinets and small control panels where eight 10/100 ports are enough and the footprint is tight. The metal housing and 12/24/48 VDC input suit packaged skids, pump stations and conveyor control boxes. Moxa’s own one-line description of the EDS-2008-EL reads: Unmanaged Fast Ethernet switch with 8 10/100BaseT(X) ports, 12/24/48 power input, metal housing, -10 to 60°C operating temperature.

From the manufacturer’s specification table, the power input is 12/24/48 VDC; operating temperature is EDS-2008-EL/EDS-2008-EL-M-SC/EDS-2008-EL-M-ST: -10 to 60°C (14 to 140°F); EDS-2008-EL-T/EDS-2008-EL-M-SC-T/EDS-2008-EL-M-ST-T: -40 to 75°C (-40 to 167°F); dimensions are EDS-2008-EL: 36 x 81 x 65 mm (1.4 x 3.19 x 2.56 in); EDS-2008-EL-M-ST: 36 x 81 x 70.9 mm (1.4 x 3.19 x 2.79 in) (w/ connector); EDS-2008-EL-M-SC: 36 x 81 x 68.9 mm (1.4 x 3.19 x 2.71 in) (w/ connector); weight is 169 g (0.37 lb).

Standards and approvals printed for this model include safety standard UL 61010-2-201; EN 62368-1. Approvals can differ between variants of a series, so check the one on the exact order code.

Technical specifications

Selecting the right variant

Pick the EL entry when you only need simple Layer 2 forwarding with no configuration, for example connecting PLC, HMI, drives and a camera on one machine. Fiber ST/SC variants of the same series exist for a single uplink beyond 100 m.

On the practical side, mounting is listed as din-rail mounting; wall mounting (with optional kit); the housing is metal; the stated MTBF is 3,696,394 hrs; the warranty period is 5 years. Treat the MTBF as a manufacturer prediction under its stated method, not a guarantee for your site.

Before ordering, confirm variant (copper-only, M-SC or M-ST fiber uplink, standard or -T wide-temperature) and the DC supply voltage in your panel. Seven Star LLC is an independent supplier in Muscat and quotes against the exact code you give us.

Related models in the EDS-2008-EL family

The Moxa product list shows these models in the same family page (6 entries): EDS-2008-EL, EDS-2008-EL-M-SC, EDS-2008-EL-M-SC-T, EDS-2008-EL-M-ST, EDS-2008-EL-M-ST-T, EDS-2008-EL-T. Suffixes such as -T generally mark wide-temperature versions and fiber suffixes (M, S, MM, SS with SC or ST) mark the connector and fiber type, but the order code printed on the datasheet governs.

Key features for panel builders

• Plug-and-play operation: no IP address, web interface or configuration is needed; connect devices and the switch learns MAC addresses automatically.
• Auto MDI/MDI-X and auto-negotiation: straight or crossover patch cables both work, and each port matches the speed and duplex of the connected device.
• Store-and-forward switching: frames are checked before forwarding, so corrupted packets are not passed on to the rest of the network.
• Wide DC input: 12, 24 or 48 VDC lets the switch share a supply with PLCs, telecom equipment or battery-backed systems.
• Compact metal housing: only 36 mm wide, saving DIN-rail space in crowded cabinets.

Unmanaged or managed: is this the right switch?

An unmanaged switch is a good fit for an isolated machine network: a PLC, HMI, a few drives and remote I/O inside one skid. It has no VLANs, no redundancy protocols and no port monitoring, so it is less suitable where the network must be segmented, where ring redundancy is required, or where the IT department needs visibility of traffic. For those cases a managed Moxa switch is the better choice, while the EDS-2008-EL keeps cost and set-up time down on simple islands.

Choosing copper or fibre

Copper RJ45 links are limited to roughly 100 m per segment under Ethernet standards. When a link must run further, cross between buildings, or pass near high-voltage cables and large drives, the -M-SC or -M-ST variant with a multi-mode fibre port provides electrical isolation and greater distance. Match the connector style, SC or ST, to the existing patch panels and fibre cable on site.

Standard or wide-temperature model

The standard models are specified for -10 to 60°C. The -T variants extend that to -40 to 75°C. In Oman and the Gulf, cabinets in direct sun, outdoor RTU kiosks and unconditioned field enclosures can exceed 60°C inside during summer, so the -T version gives useful margin there, while air-conditioned control rooms are well served by the standard model.

Installation tips

• Mount on a 35 mm DIN rail and leave space around the housing for heat to escape.
• Use the removable terminal block for power and fit a suitable fuse or protected supply output.
• Earth the housing as described in the Moxa installation guide to improve noise immunity.
• Use shielded, industrial-grade patch cables near drives and contactors.
• Label ports so maintenance staff can trace devices quickly.

Information to include in your RFQ

• Exact model: EDS-2008-EL, -M-SC or -M-ST, with or without the -T suffix.
• Quantity and any spares required.
• Matching DIN-rail power supplies, patch cables or fibre accessories if needed.
• Approval or certification requirements of the end user.
• Delivery destination and target date.
