9.4 Time behavior of the inputs and outputs
The reaction time, which is measured from the reading in of a digital input signal to the
setting of the associated output, is determined by the timing characteristics of the
device inputs and outputs as well as the size and design of the circuit diagram.
Input delay (debounce)
The time required to switch the inputs and outputs in the circuit diagram can be
increased on the easyE4 base device using an input delay, the so-called DEBOUNCE→
Section "Debounce", page 469
This function is useful, for example, in order to ensure a clean switching signal despite
contact bounce.

EASY-E4-DC-... devices and EASY-E4-AC-... devices operate with physically different
input voltages and therefore differ in the length and evaluation of debounce times.
