Product Description:
The CP6904-0000-0000 is an industrial panel PC manufactured by Beckhoff and placed within the CP Panel PC Systems series. Designed as a machine-mounted human-machine interface, it combines display, touch input, and embedded computing in one unit so operators can issue commands and view process data at the point of use. The housing separates the protected front from the rear electronics, which allows direct mounting on production equipment while keeping wiring to the control cabinet straightforward. In operation, the panel can present status screens, alarms, and control pages while the connected automation hardware manages the machine processes in the background.
Electrical service is supplied between 22 VDC and 30 VDC through a 5-pin connector that combines power and grounding in one connection. This low-voltage input suits common industrial DC power distribution and keeps the supply arrangement simple. The aluminum front is sealed to IP65, which prevents dust ingress and direct water-jet penetration, while the rear section has an IP20 rating for protected installation areas. Continuous operation is permitted in ambient temperatures up to +55 °C, and the unit remains functional at relative humidity levels up to 95% under non-condensing conditions. Two USB 2.0 ports allow local connection of flash drives, keyboards, or barcode scanners without requiring an external hub.
A maximum cable length of 50 m between this panel and its corresponding industrial PC supports flexible placement on large machines where the operator station must be located away from the main computer. Mechanical resistance includes shocks of 5 G for 30 ms and vibration with an amplitude of 0.035 mm in the 10–58 Hz range, while higher-frequency vibration is accepted up to 0.5 G. Storage is permitted from -25 °C to +65 °C, which helps the unit tolerate temperature changes before it is placed into operation. These limits suit installations where the panel is exposed to routine machine motion, transport, and normal industrial handling.
