Maximum capacitive load
- 10 nF
Maximum 72 outputs may be activated simultaneously. After 6 ms an
additional 24 outputs may be activated. The activation time for the 96
outputs must not exceed 200 ms. 48 outputs can be activated during 1
s. Continued activation is possible with respect to current
consumption but after 5 minutes the temperature rise will adversely
affect the hardware life.Maximum two relays per BOM/IOM should
be activated continuously due to power dissipation.
