The sealed IP67 housing of these modules requires no enclosure. (Note that environmental requirements other than IP67 may require an additional appropriate housing.) I/O connectors are sealed M8 (pico) or M12 (micro) or M23 styles. The mounting base ships with the module. The 1738-OB8EM23, 1738-OB8EM12, and 1738-OB8EM8 modules are shown below. 1738-OB8EM23 1738-OB8EM12 Connector M12-A 1738-OB8EM23/A 24V dc In 1738-OB8EM12/A 24V dc Out 0 2 1 3 MOD NET Connector M12-B MOD NET 0 1 2 3 0 1 LED Indicators 2 3 4 4 6 5 7 4 5 6 7 5 Connector M12-C 6 7 43862 43676 1738-OB8EM8 M23 Connector LED Indicators Connector M12-D 1738-OB8EM8/A 0.5Amp Out 24V dc 0 1 2 3 Connector M8-A MOD NET 0 Connector M8-C 1 2 4 Connector M8-E 5 3 4 6 Connector M8-G Connector M8-B 7 5 Connector M8-D LED Indicators Connector M8-F 6 7 Connector M8-G 43684 1 Publication 1738-IN001C-EN-E - June 2005 2 ArmorPoint 24V dc Output Modules, Series A . Important User Information Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (Publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://literature.rockwellautomation.com) describes some important differences between solid state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable. In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages resulting from the use or application of this equipment. The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and requirements associated with any particular installation, Rockwell Automation, Inc. cannot assume responsibility or liability for actual use based on the examples and diagrams. No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits, equipment, or software described in this manual. Reproduction of the contents of this manual, in whole or in part, without written permission of Rockwell Automation, Inc. is prohibited. Throughout this manual we use notes to make you aware of safety considerations. Identifies information about practices or circumstances that can cause an explosion in a WARNING hazardous environment, which may lead to personal injury or death, property damage, or economic loss. IMPORTANT Identifies information that is critical for successful application and understanding of the product. ATTENTION Identifies information about practices or circumstances that can lead to personal injury or death, property damage, or economic loss. Attentions help you: • identify a hazard • avoid a hazard SHOCK HAZARD • recognize the consequence Labels may be located on or inside the equipment to alert people that dangerous voltage may be present. BURN HAZARD Labels may be located on or inside the equipment to alert people that surfaces may be dangerous temperatures. Publication 1738-IN001C-EN-E - June 2005 ArmorPoint 24V dc Output Modules, Series A ATTENTION 3 Environment and Enclosure This equipment is intended for use in overvoltage Category II applications (as defined in IEC publication 60664-1), at altitudes up to 2000 meters without derating. This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11. Without appropriate precautions, there may be potential difficulties ensuring electromagnetic compatibility in other environments due to conducted as well as radiated disturbance. This equipment is supplied as ‘enclosed’ equipment. It should not require additional system enclosure when used in locations consistent with the enclosure type ratings stated in the Specifications section of this publication. Subsequent sections of this publication may contain additional information regarding specific enclosure type ratings, beyond what this product provides, that are required to comply with certain product safety certifications. NOTE: See NEMA Standards publication 250 and IEC publication 60529, as applicable, for explanations of the degrees of protection provided by different types of enclosure. Also, see the appropriate sections in this publication, as well as the Allen-Bradley publication 1770-4.1 (Industrial Automation Wiring and Grounding Guidelines), for additional installation requirements pertaining to this equipment. Publication 1738-IN001C-EN-E - June 2005 4 ArmorPoint 24V dc Output Modules, Series A Preventing Electrostatic Discharge ATTENTION This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation. Follow these guidelines when you handle this equipment: • Touch a grounded object to discharge potential static. • Wear an approved grounding wriststrap. • Do not touch connectors or pins on component boards. • Do not touch circuit components inside the equipment. • If available, use a static-safe workstation. • When not in use, store the equipment in appropriate static-safe packaging. Mount the I/O Base To mount the I/O base on a wall or panel, use the screw holes provided in the base. IMPORTANT The module must be mounted on a grounded metal mounting plate or other conductive surface. Refer to the Drilling Dimensions illustration of the base with an adapter to help you mount the base.

Lay out the required points as shown above in the drilling dimensions drawing. 2. Drill the necessary holes for #8 (M4) machine or self-tapping screws. 3. Mount the base using #8 (M4) screws. 4. Ground the system using the ground lug connection. The ground lug connection is also a mounting hole.

Using a bladed screwdriver, rotate the keyswitch on the mounting base clockwise until the number 1 aligns with the notch in the base. 2. Position the module vertically above the mounting base. The module bridges two bases. Module bridges two bases. 1738-OB8EM12/A 24V dc Out 0 2 1 3 MOD NET 0 1 2 3 4 6 5 7 4 5 6 7 43771 3. Push the module down until it engages the latching mechanism. You hear a clicking sound when the module is properly engaged. The locking mechanism locks the module to the base. Remove the Module From the Mounting Base To remove the module from the mounting base: 1. Put a flat blade screwdriver into the slot of the orange latching mechanism. 2. Push the screwdriver toward the I/O module to disengage the latch. The module lifts up off the base. 3. Pull the module off of the base.
