Product Description:
The C6920-1020-0020 industrial PC is produced by Beckhoff and belongs to the C6 Industrial PC Units series. It is configured as a control-class computer that executes PLC logic, HMI services, and data acquisition in manufacturing lines. By combining a 3.5-inch motherboard, switch-mode power stage, and multiple field connections in one enclosure, the unit replaces separate controllers and simplifies cabinet layouts within automated machinery.
The electronics are supplied from a nominal 24 VDC source that feeds the onboard regulators. Two independent Gigabit channels are exposed through 2 x RJ-45 Ethernet BASE-T sockets, allowing segregation of machine and plant networks. Peripherals such as barcode scanners or solid-state drives can be attached to 4 x USB 2.0 ports, while legacy instrumentation is supported by 1 x RS232 D-Sub-9. A single 1 x DVI-I connector drives digital or analog displays for local visualization. These interfaces sit on the 3.5-inch board and are routed directly to the front panel, so no riser cards are required. This layout maintains signal integrity and reduces assembly time.
The housing carries a protection rating of IP20, indicating finger-safe access and suitability for closed control cabinets where contaminants are limited. An eight-pin power plug rated at 16 A accepts supply leads up to 1.5 mm², matching standard control wiring without special terminations. Thermal management is handled by 2 cooling fans that draw air along the board stack and past the drive bay, preventing hot spots when the fieldbus connector and additional I/O cards are in continuous operation. The unit is suited for motion controllers, batching systems, and distributed I/O gateways installed in closed control cabinets.
