CP7120-1000-0015 by Beckhoff

The CP7120-1000-0015 is an industrial panel PC manufactured by Beckhoff within the CP Panel PC Systems series. It merges a display, computing core, and I/O interfaces into one sealed housing so that machine builders can mount visualization and control hardware directly on equipment without a separate cabinet. In typical factory lines, the unit hosts HMI runtime software, executes soft-PLC tasks, and bridges field networks to higher-level Ethernet infrastructure, streamlining the automation architecture and reducing wiring complexity.

The computer is powered by a single 24 V DC supply, allowing it to use the same low-voltage rail that serves sensors and actuators. Main memory is provided by DDR4 RAM, offering high bandwidth for multitasking operating systems and graphics workloads. Processing components sit on a compact 3.5-inch motherboard, a form factor that conserves panel depth while still providing standard headers for fieldbus cards. The integrated Gigabit controller supports cable segments up to 100 m, so the panel may be located far from switching hardware without repeaters. A front foil and aluminum bezel provide an IP65 protection rating, blocking dust and low-pressure water jets at the installation face. Security-critical keys are stored through onboard fTPM 2.0 functionality. Mass storage is accommodated by one internal 2.5-inch bay, which keeps vibration paths short for rotating or solid-state drives.

Long-term BIOS and real-time clock retention is handled by a coin cell rated at 225 mAh. This cell follows the CR2032 standard and delivers 3.0 V in a body measuring 20.0 mm in diameter and 3.20 mm in height. During transport or operation, the enclosure tolerates accelerations of 5 G for 30 ms, helping the battery, drive, and memory modules remain seated when the panel is mounted on moving gantries or subjected to mechanical shock.
