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

DC (10-30V) Input Module2

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.
