Overview
The Avalue EMS-ARH is a fanless industrial PC built on Intel's Arrow Lake-H platform, offered with Core Ultra 5 225H, Core Ultra 7 255H or Core Ultra 7 265H processors. All variants run at a 28 W PBP with Intel Arc 130T or 140T integrated graphics rated between 63 and 75 TOPS, plus Intel AI Boost at 13 TOPS — enough integrated AI throughput for vision and inference workloads without a discrete accelerator.
Memory scales to 64 GB of DDR5 at up to 6400 MT/s across two SO-DIMM sockets, and storage can be split between an M.2 2280 NVMe drive and an M.2 Key-B SATA SSD. Networking is dual 2.5GbE via Intel I226-IT controllers, with Wi-Fi 6E / Bluetooth on an E-key slot and 5G or LTE on the B-key slot with an internal SIM holder.
The differentiator is the proprietary IET expansion interface, which carries Display Interface signals, four PCIe Gen4 x1 lanes, three USB 2.0 ports, SMBus and eSPI — allowing Avalue or the integrator to add a domain-specific expansion board without consuming the standard M.2 sockets. Three independent 4K display outputs, two BIOS-selectable RS-232/422/485 ports and 8-bit GPIO complete the industrial I/O set. Avalue targets industrial, medical and transportation installations where silent operation is required.
Key Benefits
Fanless, fully silent operation for medical and controlled-environment installations. Up to 75 TOPS integrated Arc 140T graphics plus 13 TOPS AI Boost without a discrete card. Proprietary IET expansion interface adds PCIe Gen4, USB 2.0, SMBus, eSPI and display signals for custom add-ons. Triple 4K output with dual 2.5GbE and two software-selectable serial ports.
Applications
Medical imaging and clinical workstations, transportation and rail information systems, industrial automation control rooms, silent edge AI inference nodes, multi-display kiosk and control applications.
