Maximum supply voltage ripple during HART operation
• 390 mVpp at 50 Hz
• 8.3 mVpp at 300 Hz
Cycle time
The cycle time describes the time slice in which signals from the inputs are acquired and
processed.
The cycle time depends on the parameter assignment and can be dierent for each channel.
Operating mode Cycle time
Analog inputs for 60 Hz interference frequency
suppression
16.6 ms
Analog inputs for 50 Hz interference frequency
suppression
20 ms
Analog inputs for 10 Hz interference frequency
suppression
100 ms
Redundancy failover time
At an IO redundancy failover, the update time of process values is delayed once by a time less
than or equal to this time.
The maximum redundancy failover time of the I/O module is 20 ms + cycle time.
