The Beckhoff C3 Panel PC Units series consists of built-in industrial PCs designed for installation in control cabinets for machine and plant engineering applications.
Within the series, models such as the C33xx, C3620, and C3640 combine an industrial PC with an integrated TFT display, and certain versions also include front-side operating elements such as a machine-oriented keyboard, status indicators, and service-access features. The series is built around standard ATX-based PC architecture with access to storage devices, motherboard components, and optional plug-in cards, allowing expansion and maintenance from the front of the unit. Depending on the version, the systems support AC mains operation or optional 24 VDC supply and provide common industrial interfaces including USB, serial, network, DVI, DisplayPort, and optional additional cards. Overall, the C3 series is intended for panel-mounted control applications that require an integrated display-PC design, cabinet installation, and serviceable industrial computing hardware.
