C6930-1128-0060 by Beckhoff

The C6930-1128-0060 is a fanless industrial PC from Beckhoff that belongs to the C6 Industrial PC Units series. The device serves as a compact control platform for automated equipment. It hosts PLC, motion, and HMI tasks directly on the machine, removing the need for a separate control cabinet computer and reducing wiring inside automated cells.

The housing weighs 2100 g, so it can be mounted on light-gauge DIN rail without extra supports. Overall dimensions of 90 × 235 × 121 mm allow the unit to fit between standard cabinet wiring ducts. Power is supplied by a nominal 24 V DC source commonly used in control panels. Its IP20 rating protects users from contact with live parts, but the unit requires installation in an enclosure for protection against dust. Two RJ-45 sockets operate at 100/1000 Mbit/s, permitting direct connections to supervisory networks or EtherCAT field segments over cable runs of up to 100 m. Hardware authentication and encryption keys are stored in the integrated fTPM 2.0 module, enabling secure boot and data integrity functions.

Peripheral expansion is handled through four front USB ports that comply with the USB 3.0 standard, and each connector can supply up to 900 mA to external drives or service tools. Two Mini PCIe sockets provide a total of 2 internal module slots for additional fieldbus or wireless interfaces. A single DVI-I output carries a digital signal to a control-room monitor, while the RS-232 port supports legacy serial devices. The available display, network, USB, and serial connections allow the computer to communicate with common industrial peripherals without separate interface converters. The unit tolerates noncondensing relative humidity levels of up to 95 percent, making it suitable for controlled industrial enclosures where moisture does not form on internal surfaces.
