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
• 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.

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.
Figures 2.6 and 2.7 illustrate the behavior of the NC and NO terminals when
the relay is wired for failsafe, alarm or nonalarm condition or non-failsafe,
alarm or nonalarm condition.
Rockwell Automation Publication GMSI10-UM019C-EN-P - June 2011
Figures 2.8 and 2.9 show how to wire both ends of a single external indicator
to the XM terminal base for failsafe, nonalarm or alarm condition or
non-failsafe, nonalarm or alarm condition.
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.

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 125K250K500K
Thick Trunk Line500m (1,640ft.)250m (820ft.)100m (328ft.)
Thin Trunk Line100m (328ft.)100m (328ft.)100m (328ft.)
Maximum Drop Length6m (20ft.)6m (20ft.)6m (20ft.)
Cumulative Drop Length156m (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).

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.

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.
