Industrial Box PCs: Fanless Embedded Solutions for Edge AI & Automation


Industrial box PCs are compact, fanless embedded computers designed for automation, control cabinet integration, and industrial gateway applications. Selection typically depends on I/O requirements (CAN bus, serial ports, Ethernet), mounting constraints (DIN rail, wall, or VESA), expansion needs (M.2, mPCIe), and power input range. These ruggedized systems operate reliably in harsh environments where consumer hardware cannot.

Choosing the Right Industrial Box PC — FAQ

How to select the right BITECH AX-Series model for your application.

For AGV/AMR platforms, the AX-660EBT is the primary choice — it combines a 12th Gen Core i5, dual isolated CAN 2.0B, 9–36V wide input, and a PCIe x4 slot for a GPU or AI accelerator for onboard perception. If you only need CAN-based motion control without GPU compute, the AX-130BT or AX-134BT (both with CAN FD) are more compact, cost-effective options. See our AMR controller solution →

For multi-camera machine vision, the AX-320BT is purpose-built — it offers 8x 2.5GbE LAN ports for high-bandwidth camera aggregation and network segmentation. If your vision pipeline needs on-device AI inference, the AX-660EBT adds a PCIe x4 slot for a GPU or Hailo-8 accelerator alongside dual 2.5GbE.

It depends on the cards you need to run. Choose the AX-530EBT for maximum legacy capacity (3x PCI + 1x PCIe x4). Choose the AX-520EBT for a smaller migration (2x PCI, or 1x PCIe x1 + 1x PCIe x4). Choose the AX-660EBT when you need a modern 12th Gen CPU with a PCIe x4 slot for a GPU or AI accelerator rather than legacy PCI cards.

For high network-port density — bridging many Ethernet segments or building an industrial firewall — the AX-320BT with 8× 2.5GbE is the strongest fit. For 4-LAN segmentation with remote out-of-band management, the AX-134BT combines four independent GbE controllers with Intel AMT. If the gateway also needs to run vision inference on the same box, the AX-234BT adds Iris Xe graphics for OpenVINO alongside dual 2.5GbE.

The AX-422HBT is the cost-effective choice for HMI and visualization, with HDMI 2.1 + DisplayPort + USB-C driving triple 4K displays from a compact fanless chassis. For space-constrained cabinets needing CAN FD control rather than multi-display, the AX-130BT is more compact.

Isolated CAN and RS232/422/485 are available across the AX-Series, though the exact configuration varies by model. Isolation level and port count can be specified at the project level for OEM builds. How interface isolation works →

Yes. The AX-Series uses a modular mainboard architecture that lets you carry a design across Intel CPU generations without changing the validated enclosure or I/O layout. This protects your integration and certification work against component end-of-life. See our lifecycle management →

Every AX-Series Box PC is backed by 7+ years platform availability with Fixed BOM Control and formal PCN issued 6 months ahead of any component change, with a last-time-buy window. The modular mainboard architecture means a CPU generation change does not require a new enclosure or re-certification — which in practice extends the deployable life of your integration well beyond the silicon's own availability window.
