Power supply
The industrial PC is supplied with a nominal voltage of 24 V. The 8-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 5 (-24 V) and PIN 6 (+24 V) of the socket. If the industrial PC is equipped with an integrated uninterruptible power supply (UPS), an external battery pack can additionally be connected to PIN 1 and PIN 2.
Pin | Signal | Description |
|---|---|---|
8 | P-S | Power Status output, minus is the negative pole of the supply voltage |
7 | PC-ON | Input PC-ON |
6 | + 24 V | 24 V supply voltage, positive pole |
5 | - | 24 V supply voltage, negative pole |
4 |
| Protective earth |
3 | 24 V UPS | 24 V UPS output 2.5 A, minus is – BAT |
2 | + BAT | Positive pole of the battery pack |
1 | - BAT | Negative pole of the battery pack |
To operate the buffered 24 V output, you must use PIN 1 (-) and PIN 3 (+).
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 delivery. You can obtain a replacement plug from your Beckhoff Sales using the following ordering option:
