This module has four user-selectable filter time jumpers. Jumpers

JPR1 and JPR2 are used for filter times on inputs 00 through 07, and

jumpers JPR3 and JPR4 set filter times for inputs 10 through 17. The

jumper sets provide four different filter times as shown below.

These filter times apply when the input is cycling from ON to OFF.

The OFF to ON filter time is fixed at 0.57ms.

To set the filtering time constant, proceed as follows:

1. Remove the side covers from the module circuit board by

removing the four screws securing the covers to the module and

remove the circuit board.

2. Position the jumpers as required to provide the filter time

constant you require.. Use your fingers to pull the jumper up and

position it on the two pins corresponding to your selection

(0 or 1).
