C6340-0020 by Beckhoff

The C6340-0020 industrial computer is produced by Beckhoff and belongs to the C6 Industrial PC Units series. Designed as a control platform for machine automation, it runs user programs, motion logic, and visualization tasks inside a single enclosure. The fanless housing is suitable for cabinet installation where compact embedded controllers are preferred over rack-mounted PCs. By integrating directly with the TwinCAT runtime or other real-time environments, the unit manages PLC sequences, fieldbus communication, and data logging across production lines without requiring a separate control computer.

The case measures 134 mm in width, 196 mm in height, and 226 mm in depth, so it fits on shallow mounting plates. Internal electronics draw up to 150 W from a nominal supply of 24 VDC, and a front-side fuse rated at 16 A limits inrush and short-circuit currents. Power enters through a 5-pole connector that accepts field wiring up to 1.5 mm². Side ventilation slots support passive heat dissipation without requiring a cooling fan. The housing meets the IP20 protection class for use inside enclosed control cabinets, where it is protected from direct exposure to water and excessive dust.

The computer has 10/100Base-T Ethernet connectivity through two Ethernet ports with RJ-45 sockets, allowing one connection to serve the machine network and the other to handle higher-level MES traffic. This arrangement provides separate communication paths without requiring an additional network adapter. Three front USB connectors follow the USB 2.0 protocol, providing connections for service tools, storage devices, or software license dongles. Legacy serial equipment connects through the integrated 1 x RS232 interface, while a DVI-I outlet supports digital or analog monitors. The computer weighs 4.5 kg, allowing secure installation on a suitable cabinet mounting plate. Its compact dimensions and front-accessible interfaces help keep power, network, display, and peripheral wiring organized within the enclosure.
