9.4 Time behavior of the inputs and outputs
9.4.2 Delay time on EASY-E4-UC-... devices
With AC inputs the easyE4 device scans the input signal in long or short scan cycles
t
SC1
depending on whether DEBOUNCE is activated/deactivated. The scan cycle also
depends on the frequency of the supply network.
9.4.2.1 Delay time with DEBOUNCE activated
If the DEBOUNCE function is activated, the easyE4 device checks whether a positive
half-wave is present at an input terminal during two successive scan cycles t
SC1
(1st
and 2nd scan pulse at A). If the easyE4 device registers two positive half waves in suc-
cession, it switches the appropriate input (contact) internally from 0 to 1.
Figure 241: Delay times for evaluating an AC input signal and an activated DEBOUNCE
The typical input delay caused by the DEBOUNCE is therefore at least 80 ms. The cycle
time must be added to this since an easyE4 does not transfer the signal into the circuit
diagram until the start of a cycle. Conversely, the input is switched off if the easyE4
device does not detect any half-cycles twice in succession (1st and 2nd pulse at B).
t
SC1
(50 Hz) = 40 ms, tSC (60 Hz) = 33.3 ms
l
Switch-on delay (normally):
l
I1…I12: 80 ms (66.7)
l
Off-delay (normally):
l
I1…I12: 80 ms (66.7)
The corresponding values for 60 Hz are given in brackets.
