123 Aeroderivative Module

The XM® series from Rockwell Automation is the world’s first machine monitoring and protection system designed as a distributed network of modules deployed on an open standard industrial bus.

The XM-123 Aeroderivative Module is an intelligent 2-channel special-purpose monitor that is uniquely suited for monitoring Aeroderivative Gas Turbines. The XM-123 can be configured, per channel, to perform either tracking filter or band pass style measurements while it also continuously measures each channel’s broad band overall level. These capabilities, along with its extraordinary configurability, enable the XM-123 to meet the demanding monitoring requirements of almost any engine in service today.

Like the XM-120 Standard Dynamic Measurement Module, the XM-123 provides onboard processing of critical vibration parameters, advanced alarm and relay logic, easy installation and superior serviceability.

Inputs accepted include eddy current probes, standard integrated Electronics Piezo Electric (IEPE) accelerometers, or any voltage output measurement device such as a velocity or pressure transducer. In addition to vibration inputs, the modules accept one tachometer input to provide speed measurement and order tracking functions.

With two 4-20mA outputs and a single onboard relay, expandable to five, and an integral tachometer, the XM-123 Aeroderivative Module offers a complete monitoring system in a small, simple, easily installed, easily maintained package.

The XM-123 module can operate stand alone, with no interface to higher-level control systems or interactive user interfaces. It can also be deployed on a standard or dedicated DeviceNet network where it can provide data and status information to other XM modules, PLC’s, DCS and Condition Monitoring Systems.

Configuration can be performed either locally or remotely via the DeviceNet network. Local configuration is provided by the included simple and intuitive Serial Configuration Utility executing on a PC connected to the modules serial communications port. Remote configuration can be performed from any networked PC executing either any standard DeviceNet configuration software, or the XM specific XM EOL Configuration software from Rockwell Software.

NOTE: The XM-120 Standard Dynamic Module can calculate all of the same parameters as the XM-123 Aeroderivative module. However, the XM-120 calculates vector and band values in the frequency domain, rather than by applying tracking or digital filters. While this method allows the XM-120 incredible flexibility it does not provide the performance required for many gas turbine monitoring applications. When gas turbine users would prefer to use the standard XM-120, rather than the XM-123 Aeroderivative, they should first consult Rockwell Automation or reference their gas turbine manufacturers monitoring system requirements specification.
