The ARK-1251 Series is a Ultra-slim compact fanless embedded box PC designed for industrial edge computing, machine control, automation and space-constrained DIN-rail installations. Powered by Intel Core Ultra U Series processors, the platform combines efficient processing performance with a rugged, low-maintenance mechanical design, making it suitable for demanding industrial environments where reliability, connectivity and long-term availability are key.
Designed around a fanless aluminium housing, the ARK-1251 offers dependable operation without moving parts, helping reduce maintenance requirements in factory, control cabinet and edge deployment scenarios. The system supports DDR5 5600MHz SO-DIMM memory up to 96GB across two slots, giving users the memory headroom needed for modern industrial software, edge applications and multitasking workloads. It also provides flexible expansion through M.2 E Key, B Key and M Key sockets, supporting storage and wireless module integration depending on the application.
The ARK-1251 Series is particularly strong for I/O-focused industrial projects. It includes up to three Ethernet ports, four serial ports, programmable 8-bit DIO and optional CANBus support, making it well suited for connecting PLCs, sensors, controllers, field devices and industrial networks. It also includes two USB 3.2 ports and four USB 2.0 ports for peripheral connectivity, plus HDMI and DisplayPort outputs for dual display operation.
For deployment flexibility, the ARK-1251 supports 12V to 28V DC input, DIN-rail or wall mounting, TPM 2.0 for system security and extended operating temperatures from -20°C to 60°C when used with suitable peripherals and airflow. Software support includes Windows 10 Enterprise, Windows 11 Enterprise and Ubuntu 24.04, alongside support for EdgeBMC OOB, DeviceOn and Edge AI SDK. With its compact 173 x 60 x 141 mm footprint, robust I/O and modern Intel Core Ultra platform, the ARK-1251 Series is a strong choice for industrial edge, automation and embedded control applications.
