The DEBOUNCE device can be used in conjuction with the standard input device like INPUT, EINPUT, NCINPUT, ENCINPUT. The main function of this device is to eliminate the typical spikes/noises generated by a hardware switch or button.

The DEBOUNCE device computes a unitary integration in the programmed time. When the integration time is elapsed the output will become true if the computed value is greater than a pre/programmed threshold.

Typically, the main function of this device is to eliminate spikes and noises on PLC digital physical inputs.
