7.4.3.3 X524 electronic power supply
Table 7- 24
Connector
Including the current consumption for the digital outputs
1)
The maximum cable length that can be connected is 30 m.
Note
The two "+" or "M" terminals are jumpered in the connector. This ensures that the supply
voltage is looped through.
The current consumption increases by the value for the DRIVE-CLiQ node. The digital
outputs are supplied via terminals X520, X521, and X522.
7.4.3.4 X520 bidirectional digital inputs/outputs

Connector
L1+: A 24 V DC power supply for DI/DO 0 to 7 (first potential group) must always be connected if
1
at least one DI/DO of the potential group is used as an output.
M1: A ground reference for DI/DO 0 to 7 (first potential group) must always be connected if at least
one DI/DO of the potential group is used as either an input or output.
DI/DO: Bidirectional digital input/output
