- Bridges multiple devices, controllers, and sub-networks
AX-320BT Fanless Industrial PC 8-Port 2.5GbE Network Hub
Network-Focused Platform for Data-Intensive Industrial Systems
AX-320BT is engineered for network-intensive industrial environments where standard 2-port or 4-port systems cannot meet connectivity requirements. With 8× 2.5GbE LAN interfaces, AX-320BT serves as a central network aggregation node, handling large volumes of industrial Ethernet traffic across multiple devices, controllers, and sub-networks.
This platform is positioned above gateway-class Box PCs in network capability, making it suitable for applications such as data collection hubs, protocol gateways, and network aggregation points. AX-320BT focuses on routing and data handling rather than control density or AI workloads, providing the network bandwidth and processing headroom required for sustained industrial communication.

AX-320BT Technical FAQ
Expert engineering answers for system integrators and OEM developers.
Yes. The AX-320BT uses a high-performance networking architecture (Intel i211-AT and i219-LM) with optimized PCIe lanes to ensure stable, full-line-rate forwarding across all 8 ports, making it ideal for high-density data aggregation and industrial firewall applications. See our LACP & TSN networking guide →
Industrial network aggregation creates continuous thermal load. The 10W TDP design allows the AX-320BT to maintain a fanless architecture that passes PassMark 100% stress tests without thermal throttling, ensuring absolute reliability in enclosed industrial cabinets.
Absolutely. With 8 physically independent LAN ports, you can define WAN and multiple LAN segments (e.g. Production, Vision, MES, Management) at the physical controller level, making it a robust platform for software-defined firewalls (e.g. pfSense/OPNsense) and IDS/IPS systems.
Yes. To ensure data integrity in noisy industrial environments, all 4 serial interfaces feature isolation to protect against ground loops and voltage surges when connected to variable frequency drives (VFDs) or legacy PLC equipment. How interface isolation protects your system →
High-resolution multi-camera machine vision, real-time industrial IoT data streams, and centralized factory data collection hubs are the primary beneficiaries, as 2.5GbE provides significantly higher overhead to prevent packet congestion.
We utilize a unibody extruded aluminum chassis with precision-engineered heat fins. This maximizes surface area for passive heat dissipation, allowing the unit to maintain optimal junction temperatures even under 100% network throughput load.
BITECH guarantees a 10-year product availability lifecycle. Any necessary hardware component changes undergo a formal PCN (Product Change Notification) process, ensuring that your system integration and validation work remains stable over time. How our lifecycle management works →
Yes. The AX-320BT supports versatile mounting, including wall-mount, side-mount, and standard DIN-rail mounting, designed specifically for easy integration into space-constrained industrial enclosures.
Yes. One of the Ethernet ports supports Intel AMT (Active Management Technology), allowing for out-of-band KVM, remote power control, and hardware-level diagnostics, which is critical for unattended field deployments.
