Power supply
The control panel is supplied with a nominal input voltage of 24 V. The connection to the power supply and the external wiring of the control panel is established via the 4-pin M12 socket (X101). The plug is connected to + 24 V and GND.
Pin | Signal | Description |
|---|---|---|
1 | + 24 V | Power supply |
2 | GND | 0 V |
3 | GND | 0 V |
4 | + 24 V | Power supply |
The plug for the power supply is specified for 16 A. Due to the dual connection, maximum wire cross-sections of 4 x 0.75 mm2 can be accommodated. For long supply lines, use 4 x 0.75 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 control panel, so that the control panel 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:
