Connecting capacitive loads

If an F-DQ 8x24VDC/0.5A PP HF digital output module is interconnected with loads that have
an excessive capacitance, this can lead to detection of a short-circuit. Reason: The
capacitance cannot be sufficiently discharged or charged during the configured readback
time of the bit pattern test.
The typical trend shown in the diagram below represents the correlation between load
current and maximum switchable load capacitance at a supply voltage of 24 V DC.

configured max. readback time light test / dark test.
