At 180 x 165 x 67 mm, the E721 fits where rack-mount systems cannot. Wall mount, VESA, and DIN-rail installation options accommodate the physical constraints of virtually any control cabinet. Designed for fanless embedded computing, passive cooling keeps operation silent and maintenance-free at temperatures from 0 to 60°C.

The Intel Alder Lake-N platform delivers up to 8 cores and 3.80 GHz within a 15W TDP envelope. Integrated Intel Gen12 Graphics handles dual display output via DP and HDMI, covering HMI visualization, real-time control logic, and moderate machine vision and edge AI workloads within a single low-power system.

The E721 accepts a wide 9 to 36V DC input, handling the voltage surges and fluctuations common in factory and vehicle environments. An optional built-in UPS module protects against unexpected power loss, while the cable-free modular internal architecture removes a common failure point in high-vibration settings. Watchdog timer and TPM 2.0 round out the reliability features.
