Pre-installation Considerations

This document provides information on:

• important pre-installation considerations

• power supply requirements

• initial handling procedures

• installing the module

• using the indicators for troubleshooting

• module specifications

The 1771-ICD series B module must be used in a series B 1771 I/O
chassis (1771-A1B through -A4B) or a 1771-AM or -AM1 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.

European Union Directive Compliance

If this product is installed within the European Union or EEA
regions and has the CE mark, the following regulations apply.

EMC Directive

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

• EN 50081-2 EMC – Generic Emission Standard, Part 2 –

Industrial Environment

• EN 50082-2 EMC – Generic Immunity Standard, Part 2 –

Industrial Environment

The product described in this manual is intended for use in an
industrial environment.

Low Voltage Directive

This apparatus is also designed 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.

Publication 1771-5.29 – February 2000

2 DC (20-60V) Input Module Cat. No. 1771-ICD Series B

For specific information that the above norm requires, see the
appropriate sections in this manual, as well as the following
Allen-Bradley publications:

• Industrial Automation Wiring and Grounding Guidelines,

publication 1770-4.1

• Guidelines for Handling Lithium Batteries, publication AG-5.4

Open style devices must be provided with environmental and safety
protection by proper mounting in enclosures designed for specific
application conditions. See NEMA Standards publication 250 and
IEC publication 529, as applicable, for explanations of the degrees of
protection provided by different types of enclosure.

Power Requirements

Initial Handling

Your module receives its power through the 1771 I/O chassis
backplane from the chassis power supply. The module requires
250mA 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 chassis power supply.

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

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

!

961046-01 through 961046-09. (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.

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.

Publication 1771-5.29 – February 2000

• 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.

Installing Your Module

In this section we tell you how to set the fault mode selection plug,
key your I/O chassis, install your module and make your wiring
connections.

Setting the Fault Mode

You may select one of two input-failure configurations (last state or
reset) by positioning a configuration plug on the top edge of the
printed circuit board. This configuration plug is independent of the
last state switch on the I/O chassis backplane during a module fault.
During a chassis fault, the I/O chassis backplane last state switch
setting overrides the module fault mode selection.

To set the fault mode selection, proceed as follows:

1. Locate the fault mode selection plug at the top edge of the

module circuit board.

2. Using your finger, slide the plug off the two posts.

3. Carefully position the plug on two of the three posts that

correspond to your requirement.

Keying Your I/O Chassis

Use the plastic keying bands, shipped with each I/O chassis, to key
the I/O slots to accept only this type of module.

The module circuit board is slotted in two places on the rear edge.
The position of the keying bands on the backplane connector must
correspond to these slots to allow insertion of the module. You can
key any connector in an I/O chassis to receive this module except for
the left-most connector reserved for adapter or processor modules.
Place keying bands between the following numbers labeled on the
upper backplane connector:

• Between 10 and 12

• Between 18 and 20
