X522 bidirectional digital inputs/outputs

Table 6-6
Type: Screw terminal 1 (Page 321)
L3+: The 24 V DC infeed for DI/DO 16 to 23 (third potential group) must always be connected if at least
1)
one DI/DO of the potential group is used as an output.
M3: The ground reference for DI/DO 16 to 23 (third potential group) must always be connected if at
least one DI/DO of the potential group is used as an input or output.
DI/DO: Bidirectional digital input/output

X524 Electronics power supply

Table 6-7
Type: Spring-loaded terminal 6 (Page 320)
The maximum cable length is 30 m.
Note
The two "+" and "M" terminals are jumpered in the connector. This ensures that the supply
voltage is looped through.
The digital outputs are supplied via terminals X520, X521, and X522.
