Delay times for inputs and
outputs
The time from reading the inputs and outputs to switching
contacts in the circuit diagram can be set in EZ via the delay
time.
This function is useful, for example, in order to ensure a clean
switching signal despite contact bounce.
Figure 82: EZ input assigned with a switch
EZ-DC, EZ-DA, EZ-AB and EZ-AC units function with different
input voltages and therefore also have different evaluation
characteristics and delay times.
Delay times with EZ-DA and EZ-DC basic units
The delay time for DC signals is 20 ms.
