Product Overview
The Bently Nevada 3500/40 125672-01 Discrete I/O Module is a four-channel monitoring solution designed for integration within the 3500 Machinery Protection System. It accepts input from Bently Nevada proximity transducers, processes vibration and position measurements, and compares these readings to configurable alarm setpoints. Each channel can be individually programmed to perform functions such as radial vibration, thrust position, eccentricity, differential expansion, or REBAM (Rolling Element Bearing Analysis Module).
