Introduction
This chapter provides an overview of the XM-440 Master Relay module. It
also discusses the components of the module.
Introducing the XM-440
Relay Module The XM-440 Master Relay module combines four relay outputs with XM bus
master capabilities to provide remote, shared, and voted relay operation for
distributed XM measurement modules. It is a member of the Allen-Bradley™
XM
®
Series, a family of DIN rail mounted 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-440 offers four high power relays suitable for use in most protection
applications. The module also supports connecting one or two XM-441
Expansion Relay modules, providing a total of up to 12 relays.
The module provides “A Out of B” voting logic. This logic, defined uniquely
per relay, can be applied to an alarm status broadcast from XM measurement
modules located anywhere on the XM bus. The XM-440 can also send a
trigger event to a group of XM measurement modules when one or more of its
relays are activated, causing the XM measurement modules to collect their
triggered trend data.
The XM-440 module is configurable over a DeviceNet network or using a
serial connection to a PC or laptop. For list of configuration parameters for the
XM-440, refer to Chapter 3.
