Bay control REC670 2.1 IEC
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.
