Delay time with DEBOUNCE deactivated
When DEBOUNCED is deactivated, the typical delay time for
DC signals on the input caused by the hardware lies between
0.06 (IS1, IS2) and 0.17 ms (IS3 - IS14) (A). The cycle time (B)
must be added as well before the signal is safely detected in
the circuit diagram.

are free of noise. The easySafety device responds to very
short signals.

To allow reliable recognition and processing of the input
signal, it must be applied stably for a certain duration, the
length of which depends on the circuit diagram processing
cycle time.
For a guide to estimating the required minimum duration,
see Table 30 „Maximum circuit diagram processing time as
a function of the number current rungs" on page 613.
The rule-of-thumb is: Minimum duration if an input signal =
max. circuit diagram processing time ? 0.5.
