Product Overview & Description
The 3500/42M 135489‑01 + 176449‑02 is a four‑channel proximitor/seismic monitor module, forming part of a rack‑mounted machinery protection system tailored for rotating‑equipment health monitoring. The front card, designated 176449‑02, handles sensor signal acquisition and conditioning (proximity, vibration, acceleration, seismic). It processes parameters like radial vibration, axial (thrust) position, differential expansion, eccentricity, acceleration, velocity, shaft absolute position, and circular acceptance region analysis. The rear card, 135489‑01, offers isolated I/O with internal safety barriers, field wiring terminations, and manages alarm relay interfacing and back‑plane communication.
Together, they form a rugged, high‑integrity monitor featuring programmable alarms, advanced filtering (1X/2X vector, band‑pass, REBAM filters), and hot‑swap capability for uninterrupted operation.
