Debounce Time Setting - Novatech Bitronics M87X Series Manual

The output relays can be completely disabled on a per-channel basis enabling the safe
operation of the first four inputs if desired. See section 9.10.4.

9.9 Debounce Time Setting

The Digital Input Module can filter the inputs to compensate for "chattering" relays, etc.
The debounce time may be set using the 70 Series Configurator software, via the various
protocols. An input transition is not recognized until the input remains in the new state for
a time longer than the debounce time. Values between 60 ns and 4 minutes are
acceptable.
An event triggered from the digital inputs will be subject to the debounce time setting for
the digital input. Digital input traces in the Waveform and Disturbance files are the
instantaneous status of the inputs, and DO NOT reflect any debounce time settings. If a
long debounce time is set, it is possible to see an event on the digital input that does not
cause a trigger.
