CP7931-1103-C2 by Beckhoff

The CP7931-1103-C2 is a panel PC from Beckhoff that belongs to the CP Panel PC Systems series and serves as a remote human-machine interface for industrial controllers. Its aluminum housing integrates display electronics, embedded computing, and sealed field connectors so operators can command production lines without a separate enclosure. The unit is intended for mounting on machines or support arms and provides visualization, parameter entry, and diagnostic data directly at the point of manufacture.

The screen measures 12 in diagonally and uses a TFT panel to present process graphics with wide viewing angles. The sealed front has an IP65 protection rating against dust and low-pressure water jets, while the rear connectors have an IP67 rating that permits cable routing outside the cabinet. System power is supplied at 24 VDC through a four-pole M12 plug that locks against vibration. Video signals enter through a 19-pole M16 DVI connector, and USB peripherals connect to an eight-pole M9 socket that maintains the enclosure seal. The aluminum housing spreads heat while minimizing weight, and the internal components can operate in ambient humidity of up to 95%. These interface and enclosure features support installation on moving gantries, in washdown zones, or in process cells where standard office hardware is unsuitable.

The electronics remain functional at temperatures up to 55 °C, and the panel can be positioned as far as 50 m from the host computer through the remote DVI link. The unit withstands shocks of 5 G lasting 30 ms, helping protect the internal electronics and display glass on stamping presses or palletizers. For storage and transportation, the panel tolerates temperatures from -20 °C to 65 °C without condensation. The remote architecture allows the host computer to remain in a protected cabinet while the panel is installed on mobile equipment, outdoor kiosks, or high-temperature process areas.
