Allen-Bradley XM-124 Standard Dynamic
Measurement Module
The Allen-Bradley XM-124 module is an intelligent, two-channel, general-purpose monitor. The module
supports monitoring of shaft, casing or pedestal vibration in rotating equipment such as turbines, motors,
pumps, compressors, fans and most other common rotating machinery where real-time condition
monitoring or protection is required. The XM-124 module is capable of dynamic measurements from as low
as 0.2 hertz (12 CPM), making it ideal for almost any speed or type of machine, from hydro turbines to
high-speed turbo compressors. The XM-124 module accepts input from any eddy current probe, standard
accelerometer, or any voltage output measurement device such as a velocity or pressure transducer. In
addition to dynamic inputs, the module accepts one tachometer input to provide speed, phase and order
analysis functions, making it capable of calculating over 14 critical parameters per channel. The module
includes a single onboard relay – expandable to five – and two 4-20mA outputs.
