Maximum 72 outputs may be activated
simultaneously with influencing factors
within nominal range. 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/SOM should be
activated continuously due to power
dissipation.
