Introducing the XM-441 Expansion Relay Module

The XM-441 Expansion Relay module provides an additional four relays to any XM measurement module or to the XM-440 Master Relay module. It is a
member of the Allen-Bradley™ XM condition monitoring and protection modules that operate both in stand-alone applications or integrate with Programmable Logic Controllers (PLCs) and control system networks.
The XM-441 offers four high power relays suitable for use in almost any protection application. Up to two Relay Expansion modules may be connected to the XM-440 Master Relay module, providing an additional four or eight relays.
The XM-441 is not an intelligent XM module. It must be connected to either an XM measurement module or the XM-440 Master Relay module in order to function. In addition, it does not consume a node address on the DeviceNet bus. The XM-441 simply extends the circuitry of its host module.
No direct configuration of the XM-441 is required. Setup of the XM-441 relays is through its host XM measurement or XM-440 Master Relay module.

XM Installation Requirements

This section describes wire, power and grounding requirements for an XM system.

Wiring Requirements

Use solid or stranded wire. All wiring should meet the following requirements:
14 to 22 AWG copper conductors without pretreatment; 8 AWG required for grounding the DIN rail for electromagnetic interference (emi) purposes
Recommended strip length 8 millimeters (0.31 inches)
Minimum insulation rating of 300V
Soldering the conductor is forbidden
Wire ferrules can be used with stranded conductors; copper ferrules
recommended
ATTENTION
See the XM Documentation and Configuration Utility CD for Hazardous Locations installation drawings. The XM Documentation and Configuration Utility CD is packaged with the XM modules.

Power Requirements

Before installing your module, calculate the power requirements of all modules interconnected via their side connectors. The total current draw through the side connector cannot exceed 3A. Refer to the specifications for the specific modules for power requirements.
ATTENTION
A separate power connection is necessary if the total current draw of the interconnecting modules is greater than 3A.
Rockwell Automation Publication GMSI10-UM019C-EN-P - June 2011
Installing the XM-441 Expansion Relay Module 13
IMPORTANT
Power connections are not made directly to the XM-441 module. Rather power is passed via the side connector from the Expansion Module's host module. Refer to that module's User Manual for further details on power requirements.

Grounding Requirements

Use these grounding requirements to ensure safe electrical operating circumstances, and to help avoid potential emi and ground noise that can cause unfavorable operating conditions for your XM system.
DIN Rail Grounding
The XM modules make a chassis ground connection through the DIN rail. The DIN rail must be connected to a ground bus or grounding electrode conductor using 8 AWG or 1 inch copper braid. See Figure 2.1.
Use zinc-plated, yellow-chromated steel DIN rail (Allen-Bradley part no. 199-DR1 or 199-DR4) or equivalent to assure proper grounding. Using other DIN rail materials (e.g. aluminum, plastic, etc.), which can corrode, oxidize, or are poor conductors can result in improper or intermittent platform grounding.

Power Supply

The host XM module provides power, via the side connector, for the XM-441 module.

Connecting the Relays

The XM-441 has both Normally Open (NO) and Normally Closed (NC) relay contacts. Normally Open relay contacts close when the control output is energized. Normally Closed relay contacts open when the control output is energized.
The alarms associated with the relay and whether the relay is normally de-energized (non-failsafe) or normally energized (failsafe) depends on the configuration of the module. Refer to the User Guide for the specific module for a description of the Relay parameters.
Rockwell Automation Publication GMSI10-UM019C-EN-P - June 2011
Installing the XM-441 Expansion Relay Module 23
There are four double pole double throw relays in the XM-441. All relay contacts (24 total) are available for wiring at the terminal base unit, as shown in Table 2.1 on the page 23.
IMPORTANT
All XM relays are double pole. This means that each relay has two contacts in which each contact operates independently but identically. The following information and illustrations show wiring solutions for both contacts; although, in many applications it may be necessary to wire only one contact.
IMPORTANT
The NC/NO terminal descriptions (pages 20–22) correspond to a de-energized (unpowered) relay.
When the relay is configured for non-failsafe operation, the relay is normally de-energized.
When the relay is configured for failsafe operation, the relay is normally energized, and the behavior of the NC and NO terminals is inverted.

Mounting the Module

The XM-441 mounts on the XM-943 terminal base unit, Cat. No. 1440-TB-D. You should mount the module after you have connected the wiring on the terminal base unit.
ATTENTION
The XM-441 is compatible only with the XM-943 terminal base unit. The keyswitch on the terminal base unit should be at position 3 for the XM-441.
Do not attempt to install XM-441 modules on other terminal base units.
Do not change the position of the keyswitch after wiring the terminal base.
ATTENTION
This module is designed so you can remove and insert it under power. However, when you remove or insert the
module with power applied, I/O attached to the module can change states due to its input/output signal changing conditions. Take special care when using this feature.
WARNING
When you insert or remove the module while power is on, an electrical can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding.

Glossary

alarm
An alarm alerts you to a change in a measurement. For example, an alarm can notify you when the measured vibration level for a machine exceeds a pre-defined value.
Automatic Device Replacement (ADR)
A means for replacing a malfunctioning device with a new unit, and having the device configuration data set automatically. The ADR scanner uploads and stores a device’s configuration. Upon replacing a malfunctioning device with a new unit (MAC ID 63), the ADR scanner automatically downloads the configuration data and sets the MAC ID (node address).
baud rate
The baud rate is the speed at which data is transferred on the DeviceNet network. The available data rates depend on the type of cable and total cable length used on the network:
Maximum Cable Length
Cable 125K 250K 500K
Thick Trunk Line 500m (1,640ft.) 250m (820ft.) 100m (328ft.) Thin Trunk Line 100m (328ft.) 100m (328ft.) 100m (328ft.) Maximum Drop Length 6m (20ft.) 6m (20ft.) 6m (20ft.) Cumulative Drop Length 156m (512ft.) 78m (256ft.) 39m (128ft.)
The XM measurement modules’ baud rate is automatically set by the bus master. You must set the XM-440 Relay module baud rate. You set the XM-440 Relay Master to 125kb, 250kb, 500kb, or Autobaud if another device on the network has set the baud rate.
bus off
A bus off condition occurs when an abnormal rate of errors is detected on the Control Area Network (CAN) bus in a device. The bus-off device cannot receive or transmit messages on the network. This condition is often caused by corruption of the network data signals due to noise or baud rate mismatch.
Change of State (COS)
DeviceNet communications method in which the XM module sends data based on detection of any changed value within the input data (alarm or relay status).
31Rockwell Automation Publication GMSI10-UM019C-EN-P - June 2011
32 Glossary
current configuration
The current configuration is the most recently loaded set of configuration parameters in the XM module’s memory. When power is cycled, the current configuration is loaded with either the saved configuration (in EEPROM) or the factory defaults (if there is no saved configuration). In addition, the current configuration contains any configuration changes that have been downloaded to the module since power was applied.
DeviceNet network
A DeviceNet network uses a producer/consumer Controller Area Network (CAN) to connect devices (for example, XM modules). A DeviceNet network can support a maximum of 64 devices. Each device is assigned a unique node address (MAC ID) and transmits data on the network at the same baud rate.
A cable is used to connect devices on the network. It contains both the signal and power wires. General information about DeviceNet and the DeviceNet specification are maintained by the Open DeviceNet Vendor’s Association (ODVA). ODVA is online at http://www.odva.org.
EEPROM
See NVS (Non-Volatile Storage).
Electronic Data Sheet (EDS) Files
EDS files are simple text files that are used by network configuration tools such as RSNetWorx for DeviceNet to describe products so that you can easily commission them on a network. EDS files describe a product device type, revision, and configurable parameters.
Help window
A window that contains help topics that describe the operation of a program. These topics may include:
An explanation of a command.
A description of the controls in a dialog box or property page.
Instructions for a task.
Definition of a term.
MAC ID
See node address.
Rockwell Automation Publication GMSI10-UM019C-EN-P - June 2011
Glossary 33
master device
A device which controls one or more slave devices. The XM-440 Master Relay module is a master device.
node address
A DeviceNet network can have as many as 64 devices connected to it. Each device on the network must have a unique node address between 0 and 63. Node address 63 is the default used by uncommissioned devices. Node address is sometimes called “MAC ID.”
NVS (Non-Volatile Storage)
NVS is the permanent memory of an XM module. Modules store parameters and other information in NVS so that they are not lost when the module loses power (unless Auto Save is disabled). NVS is sometimes called “EEPROM.”
online help
Online help allows you to get help for your program on the computer screen by pressing F1. The help that appears in the Help window is context sensitive, which means that the help is related to what you are currently doing in the program.
Polled
DeviceNet communications method in which the module sends data in response to a poll request from a master device.
slave device
A device that receives and responds to messages from a Master device but does not initiate communication. Slave devices include the XM measurement modules, such as the XM-120 Dynamic Measurement module and the XM-320 Position module.
virtual relay
A virtual relay is a non-physical relay. It has the same capabilities (monitor alarms, activation delay, change status) as a physical relay only without any physical or electrical output. The virtual relay provides additional relay status inputs to a controller, PLC, and an XM440 Master Relay module (firmware revision 5.0 and later).
XM configuration
XM configuration is a collection of user-defined parameters for XM modules.
Rockwell Automation Publication GMSI10-UM019C-EN-P - June 2011
34 Glossary
XM Serial Configuration Utility Software
XM Serial Configuration Utility software is a tool for monitoring and configuring XM modules. It can be run on computers running Windows 2000 service pack 2, Windows NT service pack 6, or Windows XP operating systems.
