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.

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.

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.

DC (20-60V) Input Module Cat. No. 1771-ICD Series B You can change the position of these keys if system redesign and rewiring makes insertion of a different module necessary. Installing the Input Module To install the dc input module in your series B or later 1771 I/O chassis, follow the steps listed below. ! ATTENTION: Remove power from the 1771 I/O chassis backplane and field wiring arm before removing or installing an I/O module.

DC (20-60V) Input Module Cat. No. 1771-ICD Series B 5 Connect one terminal of your 2-wire input device to terminals 00 through 17. Connect the +dc line to the other terminal of your input devices. Connect terminal E to the dc common. Terminals A thru D are not used. Use stranded 14 or 16 gauge wire to minimize the voltage drop over long cable distances. Connect 3-wire input devices, such as Allen-Bradley proximity switches (Bulletin 871), to operate in a current source mode.
