Product Description:

The CP3921-1023-0011 is an industrial panel PC produced by Beckhoff within the CP Panel PC Systems series. Mounted on machine fronts or support arms, the unit combines computing electronics, a widescreen display, and a capacitive touchscreen to act as the operator interface for PLC-controlled equipment. By integrating visualization, parameter entry, and diagnostic access in one housing, it simplifies control-cabinet layouts in distributed automation cells and reduces wiring complexity.

At the front of the device sits a 21.5 in widescreen that matches a native resolution of 1920 x 1080, delivering full-HD process graphics. The projected-capacitive, or PCT, touch layer allows multitouch gestures even through thin gloves. A glass front is bonded to an aluminum chassis whose surface is electrically insulating to prevent stray currents from reaching the electronics. Environmental sealing attains an IP65 rating on the front face, so wash-down spray will not penetrate. Internally the board set is powered from a 24 VDC nominal supply, yet the input accepts down to the 22 V minimum declared for the plug. The power connector is specified for 16 A, and accepts four conductors up to 0.75 mm² each, easing daisy-chain wiring between panels.

Mechanical resilience is demonstrated by a shock tolerance of 5 G @ 30 ms, meaning the internal storage media remain operational after incidental machine impacts. During continuous operation it withstands frame vibrations of 0.035 mm from 10–58 Hz and 0.5 G between 58–500 Hz, permitting installation on stamping presses or mobile platforms without supplemental damping. With the arm adapter attached the assembly weighs 7.4 kg, while the version that terminates in a connection block lowers the mass to 6.6 kg, supporting flexible mounting strategies where load on articulated arms must be limited.
