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 Publication 1771-5.53 – April 1999 2 DC (10-30V) Input Module ! Pre-installation Considerations 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. 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. Understand Compliance to European Union Directives 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 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. Publication 1771-5.53 – April 1999 DC (10-30V) Input Module 3 Power Requirements 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. Set the Filter Off Delay 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. Top edge of circuit board Filter Delay Configuration Plug 6ms OFF 1ms OFF Off-Delay Filter Time Jumper (shown in 1ms off position) 12636-I module 3. Use your finger to slide the jumper off the 1ms position (the middle post and the right post). 4. Carefully reposition the jumper by sliding it onto the 6ms position (the middle post and the left post). Key the Backplane Connector Place your module in any slot in the chassis except the leftmost slot which is reserved for processors or adapters. ! 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. Position the keying bands in the backplane connectors to correspond to Place the keying bands: the key slots on the module. between 10 and 12 between 16 and 18 I/O chassis Upper Connector You can change the position of these bands if subsequent system design and rewiring makes insertion of a different type of module necessary. 11022-I Publication 1771-5.53 – April 1999 4 DC (10-30V) Input Module Install the Module and Field Wiring Arm ! ATTENTION: 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 1771-A1B, -A2B, -A3B, -A3B1, -A4B I/O chassis 1771-A1B, -A2B, -A3B1, -A4B Series B I/O chassis locking tab locking bar locking bar pin card guides card guides module Snap the chassis latch over the top of the module to secure it. 2 module Swing the chassis locking bar down into place to secure the modules. Make sure the locking pins engage. 19809 wiring arm Attach the wiring arm (1771-WH) to the horizontal bar at the bottom of the I/O chassis. The wiring arm pivots upward and connects with the module so you can install or remove the module without disconnecting the wires. 1771-WH remove horizontal bar Publication 1771-5.53 – April 1999 install 17643 DC (10-30V) Input Module Connect Wiring to the Field Wiring Arm 5 Make wiring connections to the field wiring arm (cat. no. 1771-WH) shipped with the module. 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 voltage drop over long cable distances. ATTENTION: Observe proper polarity with dc power connections. Reverse polarity, or application of ac voltage could damage the module. ! Connection Diagram (2-Wire Devices) Connection Diagram (3-Wire Devices) (See applicable codes and laws.)

Interpreting the Status Indicators ACTIVE 00 10 01 11 02 12 03 13 04 14 05 15 06 16 07 17 The front panel of your module contains one green module active indicator, and 16 red status indicators. Module Active Indicator (green) 00 to 17 Status Indicators (red) 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 backplane for the processor to read. See ‘‘Troubleshooting” for a description, probable causes, and recommended actions to take for common faults based on indicator responses. 10599-I Troubleshooting Use this table to help you interpret the 1771-IBD Series B status indicators and to troubleshoot module and system faults. Indicator Status (color) Description of Fault or System Status Action to Take Module active ON (green) Normal Indication None Module active ON (green) and Input status ON (red) Check for voltage on terminal. If voltage is present, take no action. If no voltage is present, replace the module.
