Response times 

A 

 

 

Introduction  

You will find the response times of the F-AI 4xI 0(4)..20mA 2-/4-wire HF below. The 

response times are included in the calculation of the F-system response time.  

Definition of response time for fail-safe analog inputs 

The response time results from the number of channels/channel pairs, the response time per 

channel/channel pair, the basic response time and the configured smoothing. 

Times required for the calculation 

●

 

Max. acknowledgment time (Device Acknowledgment Time): T

DAT

 = 20 ms 

●

 

Basic response time: 20 ms 

●

 

Response time per channel 
–

 

At 50 Hz: 25 ms 

–

 

At 60 Hz: 22 ms 

Conversion cycle time = basic response time + (N × response time per channel) 
(N = number of active channels) 
The conversion cycle time is the time in which all activated channels are 

processed/converted once. 

Typical response time  

You can calculate the typical response time of F-AI 4xI 0(4)..20mA 2-/4-wire HF using the 

following formula: 
Typical response time = Conversion cycle time × Smoothing 

Max. response time (worst case delay time, WCDT) 

You can calculate the maximum response time of F-AI 4xI 0(4)..20mA 2-/4-wire HF (worst 

case delay time, WCDT) using the following formula: 
Max. response time = 2 × Conversion cycle time × Smoothing
