Maximum capacitive load - 10 nF
Maximum 72 outputs may be activated
simultaneously with inuencing 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
