Power supply

The Panel PC is supplied with a nominal voltage of 24 V. The power supply and the protective earth of the PC are connected via the five-pin voltage socket (X101). The main supply voltage is applied between PIN 4 (0 V) and PIN 5 (24 V) of the socket. If the Panel PC is equipped with an internal, capacitive 1-second UPS (uninterruptible power supply), this is also supplied via the voltage. The 1-second UPS does not serve to back-up the operating system.

Power supply

The plug for the power supply is specified for 16 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. At least 22 V should be present at the power supply plug of the Panel PC so that the PC remains switched on in the event of voltage fluctuations. The plug is included in the delivery. You can obtain a replacement plug from your Beckhoff Sales using the following ordering option:
