Allen-Bradley ac/dc (120V)Isolated Input Installation Instructions
Rockwell Automation 1771-ID16 is an ac/dc isolated input module designed for use in industrial environments. It provides 16 isolated inputs, each of which can be configured for either ac or dc operation. The module features customer-selectable input filtering to limit the effects of voltage transients and electrical noise. It is compatible with 1771 I/O chassis Series B or later and is not compatible with the 1771-AL local I/O adapter. The 1771-ID16 is suitable for use with limit switches, float switches, selector switches, and pushbutton switches.

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.

IMPORTANT
Identifies information that is critical for
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”),

ac/dc (120V) Isolated Input Module4
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
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.
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.
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.
