Environment and Enclosure
DC (10...30V) Input Module 3
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 m (6562 ft) 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 enclosure must have suitable flame-retardant properties to
prevent or minimize the spread of flame, complying with a flame spread rating of 5VA,
V2, V1, V0 (or equivalent) if non-metallic. 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.
In addition to this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, for additional installation
requirements, Allen-Bradley publication 1770-4.1.
• NEMA Standards publication 250 and IEC publication 60529, as applicable, for
explanations of the degrees of protection provided by different types of enclosure.
Prevent Electrostatic Discharge
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.
• Use a static-safe workstation, if available.

6 DC (10...30V) Input Module
Before You Begin
The 1771-IBN series C DC input module is a sink input and requires a source output. A sink
input provides a path to ground and a source output provides a positive voltage path.
You must use this module in a 1771-A1B through 1771-A4B or later 1771 I/O chassis. Refer
to the table for processor compatibility.

This module has input filtering to limit the effect of voltage transients caused by contact
bounce and/or electrical noise. Specifications for input filtering are listed in the specifications
section of this document.
Calculate Power Supply Requirements
Your module receives its power for internal logic circuitry through the 1771 I/O chassis
backplane from the chassis power supply. The module requires 280 mA from the output of
this supply.
To calculate the requirements for the backplane power supply, add 280 mA to the power
requirements of all other modules in the I/O chassis. Calculating the requirements prevents
an overload to the chassis backplane and/or backplane power supply.
Publication 1771-IN028D-EN-P - October 2008
DC (10...30V) Input Module 7
Key the Backplane Connector
Place your module in any slot in the chassis except the leftmost slot that is reserved for
processors or adapters, noting that you:
• should position the keying bands in the backplane connectors to correspond to key
slots on the module so that you place the keying bands between 14…16 and 18…20.
• can change the position of these bands if subsequent system design and rewiring
makes insertion of a different type of module necessary.
ATTENTION
Observe the following precautions when inserting or removing keys:
• Insert or remove keys with your fingers.
• Make sure that key placement is correct.
Incorrect keying or the use of a tool can result in damage to the backplane connector and
possible system faults.

for detailed information on acceptable chassis and proper installation and
WARNING
ATTENTION
IMPORTANT
If you insert or remove the module with power applied, or connect or disconnect
the field wiring arm with field-side power applied, 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.
Remove power from the 1771 I/O chassis backplane before you install the module.
Failure to remove power from the backplane could cause:
• module damage.
• degradation of performance.
• injury or equipment damage due to possible unexpected operation.
Apply firm and even pressure on the module to seat it into its backplane connector.
To install the module and field wiring arm, follow this procedure.
1. Place the module in the card guides on the top and bottom of the chassis that guide
the module into position, noting the following:
• For a 1771-A1B, 1771-A2B, 1771-A3B, and 1771-A4B I/O chassis, snap the
chassis latch over the top of the module to secure it.
Publication 1771-IN028D-EN-P - October 2008
DC (10...30V) Input Module 9
• For a 1771-A1B, 1771-A2B, 1771-A4B I/O chassis, swing the chassis locking bar
down into place to secure the modules, making sure the locking pins engage.
2. Attach the 1771-WN wiring arm to the horizontal bar at the bottom of the I/O
chassis noting the wiring arm pivots upward and connects with the module so you
can install or remove the module without disconnecting the wires.

10 DC (10...30V) Input Module
Connecting Wiring to the Field Wiring Arm
You make connections to the module through the 1771-WN field wiring arm. The arm pivots
on the I/O chassis to connect with terminals on the front of the module and acts as a
terminal strip. The wiring arm allows the module to be removed from the chassis without
disconnecting wiring.
WARNING
WARNING
ATTENTION
The optional 1771-WHF and 1771-WHFB fused field-wiring arms are not certified for use
in hazardous location applications. Use these optional accessories only in nonhazardous
applications.
If you connect or disconnect wiring while the field-side 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.
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.
1. Be sure 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, noting that the
locking tab on the module secures it into place.
3. Make your connections to the field wiring arm as shown in the connection diagram,
using the label on the front of the wiring arm to identify your wiring.
IMPORTANT
The field-wiring arm terminal identification number is not the same as the number of the
bit that controls that output.

DC (10...30V) Input Module 11
I/O Module Groups
Each module condenses two full-module groups (32 inputs) into each I/O chassis slot. For
example:
• module group 1 = inputs 00…17.
• module group 2 = inputs 00…17 (module group 2 represents the second set of
inputs).
ATTENTION
Observe proper polarity with DC power connections. Reverse polarity or application of AC
voltage could damage the module.
In the graphic on the following page, note the following:
• Terminals 1…20 represent module group 1, with terminals 9, 10, 19, and
20 DC common.
• Terminals 21…40 represent module group 2, with terminals 29, 30, 39, and
40 DC common.
• Terminals on the left are even numbered 2…40 and terminals on the right
are odd numbered 1…39.
• If multiple power sources are used, do not exceed the specified isolation voltage.
• The arrow in the figure shows that actual wiring runs in this direction.

Status Indicators
The module has 32 status indicators on the front plate.
These represent the control status of the input. Each indicator is lit when voltage is present at
the corresponding input.
These indicators can flicker (momentarily light up) when the chassis in which the module
resides is first powered up. This flicker is normal and in no way affects the control parameters
of the system.
