Introduction
This chapter provides an overview of the XM-123 Aeroderivative module. It
also discusses the components of the module.
Introducing the XM-123
Module The XM-123 Aeroderivative module 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-123 is a 2-channel monitor designed specifically for monitoring
aeroderivative gas turbine engines, such as the General Electric LM2500
engine. The module can be configured, per channel, to perform either tracking
filter or bandpass filter while it continuously measures each channel’s
broad-band overall level.
The module can power and accept input from standard eddy current probe
systems and Integrated Electronics Piezo Electric (IEPE) accelerometers. The
XM-123 can also accept signals from most standard voltage output
measurement devices such as a velocity or pressure transducer. In addition to
vibration inputs, the XM-123 accepts one tachometer input to provide speed
measurements and order tracking functions.
The XM-123 also includes a single on-board relay (expandable to five), two
4-20mA outputs, and a buffered output for each input. The module can collect
data under steady-state and startup/coast-down conditions, and monitor up to
12 alarms making the module a complete monitoring system.
The XM-123 can operate stand-alone, or it can be deployed on a standard or
dedicated DeviceNet network where it can provide real-time data and status
information to other XM modules, PLCs, distributed control systems (DCS),
and Condition Monitoring Systems.
The module can be configured remotely via the DeviceNet network, or locally
using a serial connection to a PC or laptop. Refer to Chapter 3 for a list of the
configuration parameters.
