• For PCI-P8R8 / P16R16 / P16C16 / P16POR16

You can change the I/O card configuration simply by setting the

jumpers on this board. Each digital input channel can be jumper-

configured as a single-pole, RC filter with a time constant of 1.2 ms. The

table listed below shows each digital input channel and the

corresponding jumper.

Without Filter

For DC Signal

(Default Settling)

With AC Filter

For AC Signal

If you are using

AC input signals, you must short AC FILTER

pin2-3 of the corresponding jumpers. If you are using DC input signals,

the AC FILTER is optional. If the DC input signal response is less than

20 µs, set the filter to off. If you want a slow response (about 5 to 10 ms)

to reject either noise or contact bouncing, short AC FILTER Pin2-3.
