C6930-1032-0040 by Beckhoff

The C6930-1032-0040 is an industrial PC from Beckhoff that belongs to the C6 Industrial PC Units series. It is intended to serve as a DIN rail-mounted control platform that combines PLC, HMI, and motion tasks within automated lines. By hosting TwinCAT or other real-time software, the unit coordinates distributed I/O, drives, and vision components, acting as the central processor in an industrial automation cell.

The PC is powered from a DC bus in the range of 22-30 V DC, and the power connector is rated for 8 A so that auxiliary loads such as fieldbus interfaces can be energized without an external booster supply. Continuous operation is permitted between 0 and 55 °C, and forced-air cooling is unnecessary within this range. The aluminum housing carries an IP20 protection rating, so the unit must be installed inside a cabinet. This rating protects against accidental finger contact but does not provide water protection. Security for stored credentials and certificates is handled by an integrated fTPM 2.0 module that supports measured boot and encryption keys. Mechanical resilience is supported by a shock tolerance of 5 G for 30 ms and vibration limits of 0.035 mm from 10-58 Hz and 0.5 G from 58-500 Hz, allowing the computer to operate near stamping presses or mobile machinery.

The PC provides four USB ports, each with a current capacity of 900 mA, enabling direct attachment of scanners, flash drives, or UPS adapters. Dual LAN controllers provide two Ethernet ports for redundant networks or segmented traffic, while a single DVI-I socket supports one digital or analog monitor. Legacy peripherals can connect through the single RS-232 port. Two PCIe module slots accept fieldbus master cards or additional SSDs, extending functionality without enlarging the unit's footprint. Long-term storage and shipping are permitted at temperatures from -25 to 65 °C, allowing the computer to be stored in unconditioned environments until it is needed.
