Industrial Ethernet for Unattended, Harsh-Environment Networks
The IES100-9E is a 9 Port Industrial Fast Ethernet Switch DIN-Rail Unmanaged for control cabinets, roadside equipment rooms, building automation panels and other installations where network equipment cannot be checked every day. It provides nine 10/100Base-TX RJ45 ports, so it fits small industrial networks without adding the cost or setup work of a managed switch. Each port negotiates speed and duplex automatically, and auto MDI/MDI-X removes the need to worry about straight-through or crossover cables.
For operators, the main benefit is simple and predictable deployment. Connect the field devices, apply DC power and the switch starts forwarding traffic without an IP address, software tool or configuration step. Store-and-forward switching, wire-speed forwarding and IEEE 802.3x flow control help keep ordinary control, monitoring and automation traffic moving smoothly. The 2.0Gbps switching bandwidth and 1.488Mpps forwarding rate are suitable for compact machine networks, access control systems, PLC connections, environmental sensors and IP monitoring links that use Fast Ethernet.
Built for Control Cabinets and Remote Sites
Industrial installations often face heat, cold, electrical noise and unstable power conditions that office switches are not designed to handle. This DIN rail Ethernet switch works from -40°C to +85°C and uses a fanless metal housing with natural cooling. Removing the fan reduces a common failure point and avoids extra noise in control rooms. Power consumption stays below 5W, which helps limit cabinet heat and keeps long-running operating costs under control.
The 12-58V DC input supports the voltage range commonly found in industrial control panels, vehicles and remote power systems. Dual redundant power inputs allow a second DC source to remain connected as a backup. If one supply is interrupted, the network can continue operating from the other source. Overload protection and reverse-polarity protection also reduce the risk of wiring mistakes during installation or maintenance.
Less Maintenance for IT and Operations Teams
Imported surge protection components help protect the switch against induced high voltage and transient interference. The design also includes IEC Class A EMC protection, electrostatic discharge protection and pulse immunity for demanding electrical environments. These features do not replace proper grounding and surge planning, but they give the network a better starting point in cabinets near motors, relay equipment or outdoor traffic systems.
The compact enclosure measures 139 × 108 × 50 mm and weighs less than 0.6 kg, making it easy to fit into a crowded panel. A standard DIN-rail installation keeps the switch organized and leaves rack space for other equipment. Front-panel LEDs show link and activity status for each Ethernet port, while separate PW1 and PW2 indicators help technicians check both power inputs at a glance. IP40 protection, a high-strength metal shell and a three-year warranty make this unmanaged industrial Ethernet switch a practical choice for long-term field deployment.
Where It Fits
Use the IES100-9E for industrial control automation, road traffic control, building automation, data center monitoring, security monitoring and small machine-to-machine networks. It is a good match for system integrators, plant engineers, network installers and small businesses that need a dependable 9 port DIN-rail switch without VLAN, web management or configuration overhead. When the requirement is stable copper connectivity rather than advanced traffic control, this 9 Port Industrial Fast Ethernet Switch DIN-Rail Unmanaged keeps the installation straightforward and the service workload low.
