Fanless Industrial Box PC Intel J6412 N100 Quad 2.5G LAN RS232 RS485 Mini Computer

The EIPC-MNC4L is a low-power, fully fanless industrial box PC engineered for continuous-duty edge, gateway and networking workloads. Built on Intel Elkhart Lake (J6412 / J6413 / J6426) and Alder Lake-N (N95 / N100 / N200 / N300) platforms, it integrates four Intel i225V / i226V 2.5-gigabit Ethernet controllers inside a compact full-aluminium chassis measuring only 135 x 127 x 38.7 mm and weighing about 1 kg. Because the system runs without a fan or rotating parts, it resists dust, vibration and mechanical wear, delivering the long-term stability that factory floors, telecom cabinets, kiosks and unmanned sites demand.

• Quad 2.5G networking: Four independent Intel i225V / i226V 2.5-gigabit LAN ports support multi-WAN routing, network segmentation, soft-router and firewall builds straight out of the box.
• Truly fanless thermal design: The all-aluminium enclosure doubles as a passive heatsink, eliminating fans, filters and moving parts for silent, maintenance-free operation in dusty or confined spaces.
• Flexible Intel platform: Choose between energy-efficient Elkhart Lake J-series and the newer Alder Lake-N N95 / N100 / N200 / N300 processors to balance cost, performance and power draw.
• Dual serial connectivity: One RS-232 (DB9) and one RS-485 (4-pin Phoenix terminal) port allow direct connection to PLCs, meters, sensors and legacy field devices without extra converters.
• Dual 4K display outputs: HDMI 2.0 and DisplayPort 1.4 drive two independent high-resolution monitors for HMI, signage and monitoring dashboards.
• Versatile storage and expansion: One mSATA, one M.2 NVMe and one internal HDD / SSD bay are available, plus an M.2 Wi-Fi slot with two antenna connectors for wireless backhaul.
• Watchdog and diskless boot: A hardware watchdog timer and diskless (PXE) boot option keep unattended installations running and simplify fleet deployment.
• Rugged wide-temperature operation: Reliable from -20°C to +60°C in operation and -30°C to +70°C in storage, with 10%~90% non-condensing humidity tolerance.

The EIPC-MNC4L is purpose-built for deployments that combine heavy network traffic with harsh or space-limited environments. Its four 2.5G ports make it a natural fit for edge gateways, SD-WAN and VPN appliances, multi-WAN routers, network security and protocol-conversion boxes, and dedicated firewall nodes. In industrial automation it serves as a compact IPC for machine vision, HMI hosts, production-line monitoring and data-acquisition terminals, connecting to field equipment through its combined RS-232 and RS-485 ports. With HDMI 2.0 and DP 1.4 outputs it also drives digital signage, surveillance walls, kiosks, POS and self-service terminals. Additional deployments include smart-grid and energy monitoring, telecommunications cabinets, transportation and logistics terminals, and any unmanned site that benefits from diskless, watchdog-protected, maintenance-free operation.

Every unit is packed with an anti-static foam insert inside a shock-absorbing carton to protect the aluminium chassis during international shipping. Standard packaging contains the box PC, a matched 12V power adapter and a quick-start guide; bulk orders ship in reinforced export cartons. Each unit undergoes strict functional, temperature and aging tests before dispatch, and is backed by a 12-month warranty. CPU, memory, storage and wireless configurations can be customised, and OEM / ODM projects with custom branding, ports and firmware are welcome.
