Product Overview

The 1440-SDM02-01RA (XM-124 Standard Dynamic Measurement Module) by Allen-Bradley is a condition-monitoring I/O module within the 1440 XM series. It provides two dynamic measurement channels for accelerometers, eddy-current probes, or general-purpose voltage sensors plus one tachometer input, enabling analysis of vibration and speed in rotating machinery. Typically deployed in rotating equipment monitoring, machinery diagnostics, or predictive maintenance systems, it integrates signal processing and alarm logic directly at the machine level.
