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).
If the control panel is connected to an industrial PC via the CU8803 transmitter box, no additional power supply to the control panel is required via the voltage socket.
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:
