1 This module mounts on a 1794 terminal base unit. 1. Rotate keyswitch (1) on terminal base unit (2) clockwise to position as required for this type of module. 2. Make certain the flexbus connector (3) is pushed all the way to the left to connect with the neighboring terminal base/adapter. You cannot install the module unless the connector is fully extended. 3. Make sure that the pins on the bottom of the module are straight so they will align properly with the connector in the terminal base unit. 4. Position the module (4) with its alignment bar (5) aligned with the groove (6) on the terminal base. 5. Press firmly and evenly to seat the module in the terminal base unit. The module is seated when the latching mechanism (7) is locked into the module. 6. Repeat the above steps to install the next module in its terminal base unit.! ATTENTION: This module does not support complementary I/O. It uses both the input and output image tables since it is a combination input and output module. Allen-Bradley H

2 2! ATTENTION: Remove field-side power before removing or inserting this module. This module is designed so you can remove and insert it under backplane power. When you remove or insert a module with field-side power applied, an electrical arc may occur. An electrical arc can cause personal injury or property damage by: sending an erroneous signal to your system s field devices causing unintended machine motion causing an explosion in a hazardous environment Repeated electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance. 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 EMC Generic Emission Standard, Part 2 Industrial Environment EN EMC 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 Programmable Controllers, Part 2 Equipment Requirements and Tests. For specific information required by EN , see the appropriate sections in this publication, as well as the following Allen-Bradley publications: Industrial Automation Wiring and Grounding Guidelines For Noise Immunity, publication Guidelines for Handling Lithium Batteries, publication AG-5.4 Automation Systems Catalog, publication B111

3 3! ATTENTION: Total current draw through the terminal base unit is limited to 10A. Separate power connections to the terminal base unit may be necessary. 1. Connect the sourcing output wire to the associated input terminal on row A. 2. Connect the power wire to its associated terminal on row C (24V dc). 1. Connect the sourcing output wire to the associated input terminal on row A. 2. Connect the return wire to its associated terminal on row B ( 24V dc Return). 3. Connect the power wire to its associated terminal on row C (24V dc). Allen-Bradley H

6 6 You can select the input delay time (DT) for each group of inputs (00 through 11, or 12 through 15). Select the input delay time by setting the corresponding bits in the output image table (complementary word) for the module. For example, to set a delay time of 8ms for a dc input module at address rack 1, module group 0, set bits 05, 04, 03, 02, 01, and 00 as shown below.
