C6930-1157-0060 by Beckhoff

The C6930-1157-0060 industrial PC is produced by Beckhoff within the C6 Industrial PC Units series. It is designed as a compact DIN-rail controller for automated machines, where it handles sequencing, visualization, and communication tasks that formerly required separate devices. By consolidating real-time control and standard IT functions, the unit enables deterministic fieldbus exchange while hosting Windows or TwinCAT runtime environments, making it a central element in distributed manufacturing cells.

A nominal input of 24 V DC feeds the internal supply rails, and the spring-cage power connector is rated for up to 8 A. This connection supports the computer and attached components such as SSDs or field adapters without requiring separate power connectors. Gigabit Ethernet provides a line speed of 1000 Mbit/s, supporting high-speed network traffic over copper cable runs of up to 100 m between the computer and a switch. Two internal PCIe module slots accommodate expansion cards, while the front panel provides ports that comply with the USB 3.0 standard and can supply 900 mA per receptacle for compatible devices. The enclosure has an IP20 rating, so the computer must be installed in a protected cabinet that allows unobstructed airflow for convection cooling.

Radiated and conducted emissions comply with EN 61000-6-4, while electromagnetic immunity complies with EN 61000-6-2. These standards support stable operation near industrial equipment such as variable-speed drives and welders. The integrated firmware-based security device supports fTPM 2.0 for secure credential storage. The computer withstands shocks of 5 G for 30 ms pulses and can operate at a maximum relative humidity of 95%. Ambient operating temperature ranges from 0 °C to 55 °C without derating, and the network interfaces remain functional throughout this temperature range.
