No moving parts — the fan is physically absent, not just thermally controlled — so this unit withstands airborne dust and continuous vibration without a cooler that could fail. The -40 to 70 °C range means it lives in an unheated roof cabinet or next to a hot machine spindle without derating. The 24 V DC supply is standard for industrial panels; it holds up through 5 ms of supply dropout. Surge and burst immunity are specified per IEC 61000-4-4 and 4-5 — ±2 kV on supply lines and ±1 kV on short signal cables. The IP40 enclosure keeps out tools and fingers but isn't sealed against water; mount it in a cabinet with at least IP54 clearance. Mounting options include DIN rail, wall, or portrait orientation — three Ethernet ports provide device-level and plant network separation. Four USB 3.0 ports and a DisplayPort handle local commissioning. The SoC graphics controller drives the DisplayPort integrated, no separate GPU. Memory is fixed at 4 GB DDR4 onboard and the SSD is a factory-installed 128 GB. There are no DIMM slots or M.2 bays — this is a sealed-edge controller, not a field-upgradeable office PC. The Windows 10 IoT Enterprise 2019 LTSC image is pre-installed; an optional OS-free variant exists for Linux or custom images.","metaTitle":"Siemens 6AG1021-0AD12-2CA2 Rugged Box PC, -40 to 70 °C, Fanl","metaDescription":"Active Siemens SIMATIC Box PC 6AG1021-0AD12-2CA2: Intel Atom E3940, 4 GB RAM, 128 GB SSD, fanless, -40 to 70 °C, 24 V DC.
