SIO Series IP66/IP69K Washdown Touchscreen Computer
The SIO Series unifies advanced compute capabilities, I/O expandability and interactive display for dynamic industrial deployments. The stainless steel SIO Series are designed fanless, strong and tightly sealed to sustain punishing temperatures, harsh impacts, caustic contact and intense equipment washdowns.
- Rigid, corrosive resistant stainless-steel enclosure
- IP66/IP69K rated resilience against water and dust penetration
- Impenetrable, locking M12 I/O connectors
- 7H hardness glass resists scratches and damage
- Optical bonding standard upholds clarity in humid areas for longevity

Intel® N97 Processor
Key Features
- Intel® Processor N97 (Alder Lake-N)
- Four efficiency cores with up to 3.60 GHz boost frequency
- Low-power design optimized for fanless operation
- DDR5 memory support for improved performance and scalability
Rugged Stainless Steel Design - Reinforced for Aggressive Washdowns
Type 316 Stainless Steel & IP66/69K rated enclosure provides rigid, corrosion resistance for tough washdown cleanrooms.


Resilient, Responsive Touch Technologies
2-point PCAP touch, 7H hardness glass, and an optional high brightness display provide exceptional visibility and precise interaction. Touchscreen enable/disable control button allows the device to remain powered throughout intense high-pressure washdowns.
Scalable M.2 Expansion for Wireless Connectivity
The SIO-300-ADL Series supports cellular connectivity via an M.2 B-key expansion slot on the 21.5” and 23.8” models, enabling 4G LTE or 5G integration, and also supports Wi-Fi 6E for high-speed wireless networking.


Waterproof M12 Connectors, Straight AC-in Power
Industrial M12 connectors and direct AC power input provides secure, sealed power and I/O connectivity with simplified installation for washdown-ready hygienic environments.
Optical Bonding for Clear Visibility
Prevent condensation and increase longevity and touch accuracy by filling the vulnerable air gap between the touch panel and LCD.

Flexible Mounting Options
The SIO Washdown Touchscreen Computer integrates smoothly into workspace systems through several mounting options. The SIO may be situated on yoke or VESA mounts, or within recessed panel spaces, affording countless deployment options for industrial applications.
