Delay times for inputs and outputs
For more information visit: www.EatonElectrical.comMN05013003E 235
An input signal S1 must therefore be 15 V or 8 V (EZ-DA) for
at least 20 ms on the input terminal before the switch contact
will change from 0 to 1 (range A). If applicable, this time must
also include the cycle time (range B) since EZ does not detect
the signal until the start of a cycle.
The same time delay (range C) applies when the signal drops
out from 1 to 0.
If the debounce is switched off, EZ responds to an input signal
after just 0.25 ms.
Figure 84: Switching behavior with input debounce disabled
Typical delay times with the debounce delay switched off are:
On delay for I1 to I12:
0.25 ms (DC),
0.3 ms (EZ-DA)
Off delay for
I1 to I6 and I9 to I12: 0.4 ms (EZ-DC), 0.3 ms (EZ-DA)
I7 and I8: 0.2 ms (DC), 0.35 ms (EZ-DA)

Ensure clean input signals when the debounce is
deactivated as EZ reacts even to very short signals.
