Power supply

The panel PC is supplied with a nominal voltage of 24 V. The 2x2-pin voltage socket (X101) is used for connection to the power supply and the external wiring of the panel PC. The main supply voltage is applied between PIN 3 (0 V) and PIN 4 (24 V) of the socket.

Power supply

The plug for the power supply is specified for 8 A and can accommodate wire cross-sections of up to 1.5 mm2. For long supply lines, use 1.5 mm2 cables to achieve a low voltage drop on the supply lines. There should be at least 22 V at the power supply plug of the industrial PC, so that the industrial PC remains switched on during voltage fluctuations. The plug is included in the scope of delivery. You can obtain a replacement plug from your Beckhoff Sales using the following ordering option:
