Product Description:

The C6920-1043-0030 is an industrial PC produced by Beckhoff for the C6 Industrial PC Units series. Within an automation cell, this unit acts as the central controller, executing PLC logic, motion commands, and data acquisition tasks that previously required multiple dedicated devices. Installed on a DIN rail inside the control cabinet, it links local sensors and actuators to supervisory networks, providing deterministic control while also handling operator visualization and historical data storage in a single cabinet-mounted platform.

The computer operates from a 24 VDC supply rail common to machine cabinets. Network communication is handled through the 10/100/1000BASE-T standard, presented on dual 2 × RJ-45 jacks so separate machine and plant networks can remain isolated during operation. Four front-panel 4 × USB 2.0 ports support HMI touchscreens, maintenance drives, or license dongles at 480 Mbit/s. Visual output is provided through a 1 × DVI-I connector that supports either digital flat panels or legacy analog monitors. Internally, a 3.5-inch motherboard keeps the footprint compact yet offers a full x86 feature set, while two axial fans maintain airflow across the heat sink and memory devices for stable processing under continuous cabinet use.

The enclosure carries an IP20 protection class, preventing accidental contact with energized parts while allowing convection cooling. Mechanical resilience reaches 5 G shock loads for 30 ms, helping protect solid-state and socketed components during transport or on mobile machinery. Operation remains stable in ambient moisture levels up to 95% RH without condensation, which supports use in humid production areas. The 8-pole power header accepts 16 A on conductors up to 1.5 mm², leaving margin for startup inrush. Communication expansion includes one D-Sub-9 RS-232 service port and a separate D-Sub-9 fieldbus interface for drives or valve terminals, so the unit can connect to common machine-level serial devices without additional interface hardware.
