4.7 Response times for a 4 IQ-SENSE electronic module

Response time
The response time (t
internal memory until the specified value is obtained at the analog output - is, in the most
unfavorable case, the sum of the cycle time and the settling time. The most unfavorable case
is when the analog channel is converted shortly before the transfer of a new output value
and is not converted again until after the conversion of the other channels (cycle time).
