Ground lug

43881

This ArmorBlock MaXum I/O module (Cat. No. 1792D-8BT8PE) is a stand-alone 24V dc I/O product, which communicates via a DeviceNet network. The sealed housing of this module requires no enclosure.

This module has 8 inputs and 8 outputs accessed through Y splitter cables. Inputs are 24V dc devices. Eight self-protected 24V dc outputs can provide up to 0.5 amp each. Diagnostic features are short circuit, open wire, and no load detection reported to the connector level on inputs and point level on outputs. Local logic control has been included. An external lug exists to ground the block.

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. 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.

ATTENTION

Environment and Enclosure

This equipment is intended for use in a Pollution Degree 2 industrial environment, 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 "open type" equipment. It must be mounted within an enclosure that is suitably designed for those specific environmental conditions that will be present and appropriately designed to prevent personal injury resulting from accessibility to live parts. The interior of the enclosure must be accessible only by the use of a tool. Subsequent sections of this publication may contain additional information regarding specific enclosure type ratings 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.

Install Your ArmorBlock MaXum I/O Module

To install the ArmorBlock MaXum module:

• Set the node address

• Mount the module to the cable base

• Connect the cord sets

• Communicate with the module

Each of these steps is explained in the following procedures.

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.

• If available, use a static-safe workstation.

• When not in use, store the equipment in appropriate static-safe

packaging.

Set the Node Address

Valid node addresses are 00 through 63. Set the node address using the rotary switches, RSNetWorx for

DeviceNet, DeviceNetManager, or another software configuration tools. Setting the switches to a number from 64 through 99 lets the software have address control.

Each module is shipped set for node address 63. The switches are located on the underside of the module. The two switches are:

• MSD (most significant digit)

• LSD (least significant digit)

To reset the node address, use a small blade screwdriver to rotate the switches. Line up the small black dot on the switch with the number setting you wish to use.

The rotary switches are read at module power up only. Settings from 64 through 99 cause the module to use the last valid node address stored internally. For example, the last setting was 40. If a change is made to 68, and then you power up, the address will default to 40.

Refer to the following illustration of the node address.

The module is equipped with AutoBaud detect. AutoBaud lets the module read the settings already in use on your DeviceNet network and automatically adjusts to follow those settings.

Install the Module

This module mounts to the following cable bases:

• 1792D-CBFM for KwikLink™ flat media installation

• 1792D-CB12 for 12mm drop cable installation

• 1792D-CB18P for round media DeviceNet and output power

• other optional cable base assembly.

IMPORTANT

The cable base should already be installed. For more information about the cable base, see publication 1792D-IN036 (CB18P) or 1792D-IN009 (CBFM, CB12).

To install the module:

IMPORTANT

Proper alignment of the screws is necessary to complete the connections between the module contacts and the cable contacts.

1. Position the module over the mounted cable base. Align the three captive screws in the module with the accepting receptacles in the base.

2. Tighten the screws with a torque of 8 inch-pounds to secure the module to the base.

Note: Dimensions change according to the cable base and module combination used.
