This input module is sensitive to electrostatic discharge. This module
is shipped in static-shielded packaging to guard against electrostatic
discharge damage. Observe the following precautions when handling
this module.

Electrostatic Discharge Damage

ATTENTION: Electrostatic discharge can damage
integrated circuits or semiconductors if you touch

!

backplane connector pins. Follow these guidelines
when you handle the module:

• Touch a grounded object to discharge static potential

• Wear an approved wrist-strap grounding device

• Do not touch the backplane connector or

connector pins

• Do not touch circuit components inside the module

• If available, use a static-safe work station

• When not in use, keep the module in its original

static-shielded packaging

ATTENTION: This module is equipped with a plastic
cover that is unique to assembly numbers 960364-05

and 961344-01. (This part number is located near the
backplane edge connector pins on the component-side
of the circuit board.) Do not use this plastic cover on
any other module.

Pre-installation Considerations

Understand Compliance to European Union Directives

The 1771-IBD Series B module is compatible with all chassis except
1771-A1, 1771-A2, 1771-A4 chassis. Make sure no other input
module or single card block transfer module is placed in the same
module group when using 2-slot addressing. Any discrete output
module may be used within the same module group.

The 1771-IBD Series B module has a selectable off-delay filter time
of either 1ms or 6ms. To select the off-delay filter time, use the
procedure on page 3.

If this product has the CE mark it is approved for installation within
the European Union and EEA regions. It has been designed and
tested to meet the following directives.

EMC Directive

This product is tested to meet Council Directive 89/336/EEC
Electromagnetic Compatibility (EMC) and the following standards,
in whole or in part, documented in a technical construction file:

• EN 50081-2EMC – Generic Emission Standard,

Part 2 – Industrial Environment

• EN 50082-2EMC – Generic Immunity Standard,

Part 2 – Industrial Environment

Publication

This product is intended for use in an industrial environment.

Low Voltage Directive

This product is tested to meet Council Directive 73/23/EEC
Low Voltage, by applying the safety requirements of EN 61131–2
Programmable Controllers, Part 2 – Equipment Requirements and
Tests.

For specific information required by EN 61131-2, see the appropriate
sections in this publication, as well as these Allen-Bradley
publications:

• Industrial Automation Wiring and Grounding Guidelines For

Noise Immunity, publication 1770-4.1

• Guidelines for Handling Lithium Batteries, publication AG-5.4

• Automation Systems Catalog, publication B111

This equipment is classified as open equipment and must be mounted
in an enclosure during operation to provide safety protection.

Power Requirements

Set the Filter Off Delay

Your module receives its power through the 1771 I/O chassis
backplane from the chassis power supply. The module requires
130mA from the output of this supply. To calculate the requirements
for the backplane power supply, add 130mA to the power
requirements of all other modules in the I/O chassis. Calculating the
requirements will prevent an overload to the chassis backplane
and/or backplane power supply.

The off delay filter time is preset to 1ms. To change the filter time to
6ms, do the following:

1. Turn off power to the I/O chassis.

2. Locate the off-delay filter time configuration plug on the top-left

edge of the printed circuit board as shown below.

performance, or injury.

• Failure to remove power from the backplane could

1. Connect one terminal of your two or three-wire input device to

terminals 00 through 17.

2. Connect the +dc line to the other terminal of your input devices.

Connect three-wire input devices, such as Allen-Bradley
proximity switches (Bulletin 871), to operate in a current source
mode.

3. Connect terminal E to the dc common. Terminals A thru D are

not used. Use stranded 14 or 16 gauge wire to minimize the

Important: You can directly drive terminals on a DC (10-30V)

Input Module (cat. no. 1771-IBD Series B) from
terminals on the following modules:

• DC (10-30V) Output module (cat. no. 1771-OBN)

• DC (10-60V) Output module (cat. no. 1771-OBD)

• DC (12-24V) Output module (cat. no. 1771-OB)

• DC (24V) Output module (cat. no. 1771-OQ)

• DC (24V) Output module (cat. no. 1771-OQ16)

Important: Use the same dc power source to power both modules

to ensure that ground is at the same potential.

Interpreting the Status Indicators

The front panel of your module contains one green module active
indicator, and 16 red status indicators.

The green active indicator turns on when the module is powered. The
red status indicators are provided for system logic side indication of
individual inputs. When a red status indicator lights, voltage is
present on the terminal. The module transfers this information to the
