This module must be used in a series B or later 1771 I/O chassis. The
1771-ID16 is not compatible with the 1771-AL local I/O adapter.
This module contains customer-selectable input filtering to limit the
effects of voltage transients caused by contact bounce and/or radiated
electrical noise. The delay due to filtering is 9.0 or 18.0ms for
turning ac inputs on to off, and 0.57ms for turning ac inputs off to
on: 9.0ms for turning dc inputs on to off, and 0.57ms for turning dc
inputs off to on. The filter time is factory set to 9.0ms.
The module is designed to operate with limit switches, float
switches, selector switches, and pushbutton switches.

Identifies information that is critical for
IMPORTANT successful application and understanding of the
product.
ATTENTION
!
This equipment is intended for use in a Pollution
Degree 2 industrial environment, in overvoltage
Category II applications (as defined in IEC
publication 60664–1), at altitudes up to 2000
meters without derating.
This equipment is considered Group 1, Class A
industrial equipment according to IEC/CISPR
Publication 11. Without appropriate precautions,
there may be potential difficulties ensuring
electromagnetic compatibility in other
environments due to conducted as well as radiated
disturbance.
This equipment is supplied as “open type”
equipment. It must be mounted within an
enclosure that is suitably designed for those
specific environmental conditions that will be
present, and appropriately designed to prevent
personal injury resulting from accessibility to live
parts. The interior of the enclosure must be
accessible only by the use of a tool. Subsequent
sections of this publication may contain additional
information regarding specific enclosure type
ratings that are required to comply with certain
product safety certifications.
See NEMA Standards publication 250 and IEC
publication 60529, as applicable, for explanations
of the degrees of protection provided by different
types of enclosures. Also, see the appropriate
sections in this publication, as well as the
Allen–Bradley publication 1770–4.1, (“Industrial
Automation Wiring and Grounding Guidelines”),
for additional installation requirements pertaining
to this equipment.

ac/dc (120V) Isolated Input Module
Initial Handling
The isolated input module is shipped in a static-shielded packaging
to guard against electrostatic discharge damage. Observe the
following precautions when handling the module.
ATTENTION
!
Calculate Power
Requirements
Preventing Electrostatic Discharge
This equipment is sensitive to electrostatic
discharge, which can cause internal damage and
affect normal operation. Follow these guidelines
when you handle this equipment:
• Touch a grounded object to discharge potential
static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component
boards.
• Do not touch circuit components inside the
equipment.
• If available, use a static–safe workstation.
• When not in use, keep modules in appropriate
static–safe packaging.
Your module receives its power through the 1771 I/O chassis
backplane from the chassis power supply. The module requires
75mA from the output of this supply. Add this to the requirements of
all other modules in the I/O chassis to prevent overloading the
chassis backplane and/or backplane power supply.
Set the Filter Time
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 Table A
for filter times and jumper settings.
Half cycle dropout protection is dependent upon
IMPORTANT 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.
ac/dc (120V) Isolated Input Module

To set the filtering time, 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 you
require (see below). Use your fingers to pull the jumper up and
position over the 2 pins corresponding to your selection (Fast or
Norm).

The 1771–ID16/B module is a modular component of the 1771 I/O
system requiring a properly installed system chassis. Refer to
publication 1771–IN075 for detailed information on acceptable
chassis, proper installation and grounding requirements. Limit the

ac/dc (120V) Isolated Input Module
Connections to the input module are made to the 40 terminal field
wiring arm (cat. no. 1771-WN) shipped with the module. Attach the
wiring arm to the pivot bar on the bottom of the I/O chassis. The
wiring arm pivots upward and connects with the module so you can
install or remove the module without disconnecting the wires.
1. Make certain all power is removed from the module before
making wiring connections.
2. Swing the wiring arm up into position on the front of the module.
The locking tab on the module will secure it into place.
WARNING
!
When you connect or disconnect the field wiring
arm with field power applied, or remove the
module while backplane power is on, an electrical
arc can occur. This could cause an explosion in
hazardous location installations.
Be sure that power is removed or the area is
nonhazardous before proceeding.
ATTENTION
!
Remove power from the 1771 I/O chassis
backplane and field wiring arm before removing
or installing an I/O module.
• Failure to remove power from the backplane or
wiring arm could cause module damage,
degradation of performance, or injury.
• Failure to remove power from the backplane
could cause injury or equipment damage due to
possible unexpected operation.
3. Make your connections to the field wiring arm as shown in the
following figure. (Use the label on the front of the wiring arm to
identify your wiring.)
Note: A shorting bar may be used to connect the commons if
channel-to-channel isolation is not required.
