Product Overview & Description
The 3500/40M 176449‑01 + 125680‑01 is a four‑channel Proximitor Monitor designed for online vibration and displacement monitoring of rotating machinery. It belongs to the 3500 Series Machinery Monitoring System and plugs into a 3500 rack. The unit accepts proximity transducer inputs and delivers conditioned signals, enabling measurement of multiple parameters such as radial vibration, axial (thrust) position, differential expansion, eccentricity, and advanced diagnostics like REBAM (Rolling Element Bearing Analysis Measurement). Embedded alarm logic and hot‑swappable design allow continuous operation and efficient maintenance.
The module comes pre‑terminated with the 125680‑01 I/O module, which supplies seamless internal termination and interface connectivity.
