Product Overview & Description
The 3500/42M 140734‑02 + 135489‑01 is a dual‑module, rack‑mounted protection monitor engineered for rotating machinery health surveillance. The 140734‑02 front card manages signal conditioning from proximity and seismic transducers, capturing metrics like radial vibration, axial (thrust) displacement, differential expansion, eccentricity, acceleration, velocity, shaft absolute position, REBAM diagnostics, and circular acceptance region. The 135489‑01 rear card offers internal termination with safety barriers, streamlined field wiring, and alarm relay integration—all while maintaining hot‑swap capability for maintenance without interrupting system operation.

Applications
Suited for safeguarding critical rotating machinery such as turbines, compressors, pumps, and generators, this module enables real‑time monitoring of a wide array of mechanical parameters. Its multi‑sensor capability allows detection of early mechanical faults like misalignment, imbalance, bearing deterioration, or thermal expansion trends. The rear card’s built‑in safety barriers make it ideal for hazardous and demanding environments. Hot‑swap functionality and flexible analog outputs simplify integration into DCS, SCADA, and predictive maintenance frameworks.
