The BECKHOFF CP6903-0020-0000 is an Economy built-in Control Panel engineered for machine-level visualization and operation in industrial environments. Featuring a 19-inch TFT display with a resolution of 1280 x 1024 pixels (SXGA), this unit operates as a dedicated visual terminal without an integrated keyboard or touch sensor. It incorporates a front-accessible USB 2.0 Type-A socket protected by an IP65 screw-on cap, allowing maintenance personnel and operators to connect USB peripherals directly from the front of the enclosure without opening the control cabinet.
Built for remote operation with an industrial PC, the CP6903-0020-0000 integrates BECKHOFF DVI-E and USB-E 2.0 transmission technology. This interface enables graphic and USB data transmission over distances of up to 50 meters between the control panel and the central IPC using standard digital video cabling and Cat.5 Ethernet wiring. A built-in graphics processing receiver reconstructs incoming digital video signals, while the integrated USB hub provides two additional downstream USB ports on the rear for peripheral connections.
Mechanical mounting is achieved using integrated pull-out clamping levers that pull the aluminum front bezel tightly against the enclosure cutout. This design provides front-side IP65 ingress protection against dust and water jets while eliminating loose mounting hardware during installation and servicing.
