System manual CECX / Digital input/output module CECX-D-8E8A-NP-2
CECX-II 17-13
After the short circuit has been rectified the
system.DOx_stat
flag is re-
set, information about the rectification of the error is generated, and the
output becomes available again.
17.6.2 Debouncing
The inputs are filtered with a default debouncing time of 1 ms.
To suppress interference signals from switches, keys etc, a debouncing
time of 100 ms can be set in the configuration. The signal must therefore be
applied for at least 100 ms at the input, for it to be recognized and proc-
essed by the system.
Information
The debouncing function is possible only when the digital input is not used
as interrupt input.
If the input is configured as interrupt input, debouncing takes automatically
place with 34
μ
s.
17.6.3 Switching inductive loads
The module contains no internal freewheeling diode to take up the inductive
energy when switching off the inductive loads.
The inductive load capability for each channel is 1 J at 0.2 Hz.
The inductive energy is transformed into heat by the switching transistor. It
sets itself a voltage of -60 V. This allows for a swifter breakdown of the en-
ergy than would be possible when using the freewheeling diode.
Information
The load capacity of the outputs for inductive loads can be raised by adding
an external freewheeling diode, which will, however, significantly increase
the switch-off time.
In the case of high load currents, higher values of inductance or greater
switching frequency, a freewheeling diode must always be used.
