The Bently Nevada 3500/40M 126615-01 Proximitor Seismic Monitor I/O Module is designed for precise machinery protection and condition monitoring. It accepts inputs from up to four proximity transducers, processes vibration and position measurements, and compares them against user-configurable alarm thresholds. Supporting functions such as radial vibration, thrust position, eccentricity, REBAM, and differential expansion, it ensures critical equipment safety by continuously monitoring performance parameters. Each channel can be independently configured via the 3500 Rack Configuration Software, enabling flexible and efficient machine diagnostics.
