Industrial Gigabit Switching for Harsh Network Sites
IES300-4E1F is an unmanaged 4 Port Gigabit Industrial Ethernet Switch with 1 SC Fiber Port, designed for network cabinets, control panels, roadside cabinets, and small industrial communication nodes. It connects four copper Ethernet devices to a long-distance optical fiber link without requiring software setup or an on-site network specialist. For teams that need to extend a factory, traffic, building automation, or monitoring network quickly, this switch keeps deployment straightforward: connect the copper devices, connect the fiber, apply DC power, and the link is ready.
The four RJ45 ports support 10/100/1000Mbps auto-negotiation, half/full-duplex auto-negotiation, and automatic MDI/MDI-X. This allows the switch to work with existing controllers, PLC communication devices, computers, cameras, access control equipment, and other Ethernet terminals without manually setting port speed or cable type. Each RJ45 port supports line-rate forwarding, helping traffic move smoothly when several local devices share the fiber uplink. Store-and-forward switching checks incoming frames before forwarding them, which is a practical choice for mixed-speed industrial networks.
Fiber Uplink for Distance and Electrical Isolation
The 1 1000Base-X SC fiber port provides a clean way to connect remote cabinets, production areas, buildings, or roadside equipment. Depending on the selected optical module configuration, the link can support multimode transmission up to 550m or 2km, and single-mode distances from 2km to 100km. Optical transmission also helps separate network segments electrically, reducing the effect of ground potential differences and electrical noise across long cable routes. The product is identified as a 4 Port Gigabit Industrial Ethernet Switch with 1 SC Fiber Port, while FC or SFP options may be available for specific project requirements.
Built for Unattended Industrial Operation
Industrial sites rarely provide a clean, temperature-controlled environment. IES300-4E1F uses a fanless metal housing, natural cooling, and a -45°C to +85°C operating temperature range. With no cooling fan to wear out or collect dust, the switch can remain in a control cabinet, outdoor traffic box, or machine-side enclosure with less routine maintenance. The IP40 enclosure, IEC Class A EMC protection, surge protection, electrostatic discharge resistance, and pulse immunity help the switch handle common electrical interference found around motors, power equipment, and long cable runs.
Dual redundant DC power inputs accept 12V to 58V DC. If one power feed is interrupted, the second feed can help keep the network node online, which is useful for traffic control, industrial automation, and surveillance systems where an unexpected reboot can interrupt operations. Overload protection and reverse-polarity protection reduce installation risk, while the six-pin Phoenix terminal provides a practical connection for cabinet wiring. Power consumption stays below 5W, helping limit heat build-up and ongoing energy use in installations with many field switches.
Simple Deployment for IT and Field Teams
As an unmanaged industrial Ethernet switch, the unit requires no IP address, web interface, VLAN planning, or firmware configuration. Status LEDs provide a quick view of power, copper link/activity, speed, and fiber status during commissioning or troubleshooting. The DIN-Rail mounting design saves cabinet space and makes replacement easier for maintenance staff. With a 16K MAC address table, 10Gbps switching bandwidth, 7.44Mpps forwarding performance, and support for jumbo frames up to 10K, it fits small industrial networks that need dependable Gigabit connectivity rather than complex management features.
This switch is a practical fit for industrial control automation, road traffic control, building automation, computer room monitoring, IP surveillance backhaul, and distributed equipment rooms. It is intended for network installers, control engineers, IT administrators, and system integrators who need a stable fiber-connected Ethernet node, simple installation, and predictable long-term operation.
