Power supply

The industrial PC is supplied with a nominal voltage of 24 V. The 4-pin voltage socket (X101) is used for connection to the power supply and the external wiring of the industrial PC. The main supply voltage is applied between PIN 1 (0 V) and PIN 2 (24 V) of the socket.

The plug for the power supply is specified for 16 A and can accommodate wire cross-sections of up to 2.5 mm2. Always use wire cross-sections of 2.5 mm2 to achieve a low voltage drop on the supply cables. The cable length is limited to a maximum of 5 m. A nominal voltage of at least 22 V must always be applied to the power supply plug of the industrial PC so that the industrial PC remains switched on even during voltage peaks and voltage fluctuations. The plug is included in the delivery. You can obtain a replacement plug from your Beckhoff Sales using the following ordering option:

A maximum cable length of 30 m is permissible for the Power Status output.
