Installation Instructions ArmorPoint Relay Output Modules, Series A (Cat. No. 1738-OW4M12 and -OW4M12AC) The ArmorPoint I/O family (Cat. no. 1738) consists of modular I/O modules. 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 M12 with either DC or AC keyed (micro) styles. The mounting base ships with the module.
ArmorPoint Relay 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://www.ab.com/manuals/gi) describes some important differences between solid state equipment and hard-wired electromechanical devices.
ArmorPoint Relay 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.
ArmorPoint Relay Output Modules, Series A ATTENTION Preventing Electrostatic Discharge 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.

ArmorPoint Relay Output Modules, Series A 3. Push the module down until it engages the latching mechanism. You will hear a clicking sound when the module is properly engaged. The locking mechanism will lock the module to the base. Remove the ArmorPoint Relay Output 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.
ArmorPoint Relay Output Modules, Series A Wire the Relay Output Modules 7 Following are wiring instructions for the ArmorPoint relay output modules.
ArmorPoint Relay Output Modules, Series A Communicate With Your Module I/O messages are sent to (consumed) and received from (produced) the ArmorPoint I/O module. These messages are mapped into the processor’s memory. The ArmorPoint I/O relay output module consumes 1 byte of output data (scanner Tx - status). It does not produce data (scanner Rx).
