Arestech SB-5516-1A1 Intel Core Ultra 200S (Arrow Lake) Fanless Embedded PC with Intel NPU and Dual GbE

Defect detection and AGV or AMR motion control increasingly run AI models at the machine rather than in a server room, and that calls for current Intel silicon in an enclosure with no fan to clog. The SB-5516-1A1 is the standard I/O model in the Arestech SB-5516 series, a fanless embedded PC for Intel Core Ultra 200S processors aimed at edge AI, machine vision and real-time data analytics. It shares its board and enclosure with the SB-5516-1A2, which adds 16 isolated inputs and 16 isolated outputs.

The LGA1851 socket takes 35 W Core Ultra (Series 2) processors, with Arestech listing the Core Ultra 9 285T, Ultra 7 265T and Ultra 5 245T. Each carries an integrated NPU alongside the CPU cores and Intel graphics, so inference can run on the NPU while the cores handle control and logging. The Intel H810 chipset supports dual-channel DDR5 at 5600 or 6400 MHz across two SO-DIMM sockets, up to 128 GB, and TPM 2.0 is fitted on the board.

On the SB-5516-1A1, two GbE ports can separate a camera network from the plant network, HDMI 2.1 reaches 7680 x 4320 and DisplayPort 4096 x 2160, and four USB 3.2 ports (two Gen2, two Gen1) take cameras and peripherals. One RS-232 and one RS-232/422/485 port, a four-in, four-out GPIO header, line-out and mic-in complete the I/O, and a flexible I/O window leaves room for extra interfaces. Storage is an M.2 2280 M-Key slot with PCIe Gen4 x4 or SATA plus two removable 2.5″ SATA SSD trays, and an M.2 E-Key slot takes an optional Wi-Fi module.

Power is 19 to 24 V DC on a two-pin terminal block with AT and ATX modes. The fanless enclosure operates from -20 °C to 60 °C, is tested to 5 Grms vibration and 50 G shock under IEC 60068 and carries CE and FCC Class A marks and wall mounts. We supply the SB-5516-1A1 configured, with Windows 11 or Linux installed, and tested before it ships. Where the cell needs a sealed enclosure around a Core Ultra processor, the SB-5825B is rated IP66 with M12 connections.
