The ARK-1251-S3A1 is a fanless embedded box PC built for industrial control, edge computing and automation systems that require efficient processing, compact installation and dependable I/O connectivity. Equipped with an Intel Core Ultra 5 125U processor, this model provides a strong balance of performance and power efficiency for applications such as machine monitoring, data collection, equipment control, industrial gateways and local edge workloads.
The system is designed in a rugged aluminium housing with a fanless thermal design, helping to improve reliability in environments where dust, vibration or limited maintenance access can make fan-based systems less desirable. With support for up to 96GB of DDR5 5600MHz SO-DIMM memory across two slots, the ARK-1251-S3A1 can handle modern industrial operating systems, control software, remote management tools and edge applications. It also provides three M.2 expansion positions, including M.2 B Key, E Key and M Key, enabling flexible configuration for NVMe storage, SATA storage and wireless module installation.
Connectivity is a major advantage of the ARK-1251-S3A1. It includes three LAN ports, four COM ports, two USB 3.2 ports, four USB 2.0 ports, 8-bit programmable DIO, audio with mic-in and line-out, one HDMI output, one DisplayPort output and a SIM slot. This gives system builders a compact but highly capable platform for connecting industrial devices, legacy serial equipment, networks, displays and peripheral hardware.
The ARK-1251-S3A1 supports 12V to 28V DC input and is suitable for DIN-rail or wall-mounted installations. It is rated for extended operating temperatures from -20°C to 60°C with suitable peripherals and airflow, and includes TPM 2.0 for hardware-based system security. With support for Windows 10 Enterprise, Windows 11 Enterprise and Ubuntu 24.04, the ARK-1251-S3A1 is a practical choice for reliable industrial edge deployments where efficient performance and broad connectivity are required
