Product Description:
The C6140-0040 is an industrial PC manufactured by Beckhoff as part of the C6 Industrial PC Units series. It serves as a cabinet-mounted computing node that runs PLC, motion-control, and HMI software for centralized machine supervision. The steel enclosure places field connections on the front panel, allowing direct wiring of drives, sensors, and supervisory networks without separate gateway hardware. This arrangement helps simplify system layout in industrial automation cells where cabinet access and cable routing need to remain straightforward.
The enclosure measures 362 mm in height, 383 mm in width, and 265 mm in depth, dimensions that fit standard 19-inch mounting areas while still leaving room for airflow. Its service weight is 14 kg, so the unit can be handled during installation or removal without lifting equipment. Power consumption stays within a 100 W budget, allowing the IPC to share a modest 24 V DC source with I/O terminals. The housing has an IP20 rating, which limits use to dry, enclosed cabinets and supports heat dissipation through natural convection. A five-pole power connector with 5 mm contact spacing accepts conductors down to 1.5 mm², and three audio jacks provide line-level sound for operator panels. Two serial ports are also available for legacy peripherals.
The housing resists shocks up to 5 G for 30 ms, which helps protect the electronics during transport or machine impact. Operation is permitted at ambient humidity levels as high as 95% without condensation. Four front-mounted USB ports support removable media, service keyboards, and barcode scanners, while the single Ethernet port provides high-speed communication to EtherCAT segments or plant networks. These front-access interfaces make the unit suitable for control cabinets that require both local service access and network connectivity from the same enclosure face.
