Monitoring contact closure at an input

To ensure that the KPCI-PIO96 reliably monitors an open contact as an input-high condition, 

connect a 10 k

Ω

 pull-up resistor between the input line and a +5 VDC source. See Figure 3-4.

Eliminating contact bounce

The effects of contact bounce may be eliminated  by programming in your application software. 
However, it is often desirable to eliminate contact bounce from the signal, using a  de-bounce 
circuit between the contacts and the KPCI-PIO96 input. Figure 3-5 shows a typical de-bounce 
circuit that can be used with Form C contacts.
