EL900-A-C-1-A Industrial Fiber Media Converter (ST) 2km

EL900-A-C-1-A Hardened Ethernet to Multimode Fiber Media Converter

10/100 Mbps Ethernet to 100 Mbps multimode fiber with ST connectors and up to 2km reach.

Hardened operation from −40 to 75°C (−40 to 167°F).

The EtherWAN EL900-A-C-1-A connects copper Ethernet equipment to multimode fiber in demanding industrial installations. It combines one RJ45 Ethernet port with a built-in 1310nm ST fiber interface, providing Fast Ethernet connectivity for transportation, utility, manufacturing, and surveillance networks.

Its rugged aluminum housing resists shock and vibration, while redundant DC power inputs and a fault alarm relay help support dependable operation. Link Fault Pass Through (LFPT) allows connected equipment to detect a failed copper or fiber link.

Key Features

• Fast Ethernet connectivity: One 10/100 Mbps RJ45 port and one 100 Mbps multimode ST fiber port.
• 2km multimode reach: Supports compatible fiber links up to 2km, subject to the link’s optical losses.
• Hardened operation: Rated from −40 to 75°C (−40 to 167°F).
• Industrial durability: Aluminum IP30 housing with resistance to shock, vibration, and electrical interference.
• Redundant DC power: Accepts 10–48VDC through terminal-block connections.
• Fault monitoring: Alarm relay provides indication of power or link failure.
• Link Fault Pass Through: Passes a copper or fiber link failure indication to connected equipment.
• Hazardous-location certification: ISA 12.12.01 Class I, Division 2, Groups A, B, C, and D.
• Traffic-control suitability: Meets NEMA TS1/TS2 environmental requirements for traffic-control equipment.
• Flexible installation: Includes a mounting kit for standard 35mm DIN rail, with optional panel mounting.

Applications

• Ethernet-to-fiber connections in industrial control cabinets.
• Transportation and roadside traffic-control networks.
• Utility and manufacturing installations exposed to temperature changes.
• IP surveillance networks using compatible 100 Mbps multimode fiber equipment.

Common Questions

Is a power supply included?
No. This model requires an external 10–48VDC power source connected to its DC terminal block. Compatible 24VDC power supplies are available separately. Wiring from the power supply to the converter is also required.

Does this converter need an SFP module?
No. Its 1310nm multimode ST fiber interface is built in. Use compatible 100 Mbps multimode optics at the other end of the fiber link.

Can it be installed outdoors?
Yes, inside a suitable protective cabinet or enclosure. Its hardened temperature rating supports demanding outdoor cabinet installations, but the IP30 housing must be protected from rain and moisture.
