ac (120V) Isolated Input Module

3

Publication 1771-IN001A–EN–P – May 2000

The isolated input module is shipped in a static-shielded bag to guard
against electrostatic discharge damage. Observe the following
precautions when handling the module.

Electrostatic Discharge Damage

!

ATTENTION: Under some conditions, electrostatic

discharge can degrade performance or damage the

module. Observe the following precautions to guard

against electrostatic damage.

Wear an approved wrist strap grounding device, or touch a
grounded object to discharge yourself before handling the
module.

Do not touch the backplane connector or connector pins.

If you configure or replace internal components, do not touch
other circuit components inside the module. If available, use a
static-free work station.

When not in use, keep the module in a static-shielded bag.

The input module has 2 customer-selectable input filter time
jumpers. Jumper JPR 1 sets the input filter time for inputs 00 through
07, and jumper JPR 2 sets the input filter time for inputs 10 through
17. These filter times apply when the input is cycling from ON to
OFF. The OFF to ON filter time is fixed at 0.57ms. Refer to the
figure on page 4 for filter times and jumper settings.

Important:

Half cycle dropout protection is dependent upon the
position of the jumpers. With the jumpers at the 9.0ms
position (Fast), half cycle protection may not be
guaranteed. If half cycle dropout protection is required,
position the jumpers in the 18.0ms position (Norm).
Maximum and minimum filter times are shown in
Table A.
