Power & Redundancy
-
What is the benefit of the Pretech 8-inch Tablet with USB C and DC in for industrial use?
The Dual Power Supply (USB Type-C and DC-In) provides essential power redundancy. This feature guarantees continuous operation, making it ideal for critical Industrial Control and Commercial Display systems that require uninterrupted power across North America and Europe.
-
Is the battery removable for permanent, fixed installations?
Yes. For most permanent HMI applications, we can provide the device optimized for Battery-Free Operation when connected to DC power. This eliminates battery maintenance and swelling risks for 24/7 Wall-Mount Control Panel deployments.
Connectivity & HMI
-
How does the USB Host port support complex HMI integration?
The dedicated USB Host port ensures robust connectivity for critical external peripherals, such as Scanners, Payment Devices, specialized Sensors, or Printers. This transforms the 8-inch HMI Tablet into a versatile Data Collection and User Interface hub.
-
Why is an 8-inch display optimal for HMI Solutions?
The 8-inch form factor provides a large, clear display for detailed application UIs (User Interfaces) while remaining compact enough for panel-mounting. It offers superior visualization for tasks like Machine Diagnostics or Complex Building Management Systems (BMS).
Customization (ODM)
