Product Overview & Description
The 3500/42 176449‑02 + 128240‑01 is a dual‑card module designed for high‑integrity vibration and mechanical diagnostics in a rack-mounted protection system. The 176449‑02 front card handles precision signal conditioning for proximity, velocity, and acceleration sensors, allowing for real-time tracking of radial vibration, axial displacement, shaft expansion, and eccentricity. Dedicated diagnostic modes like REBAM (Rolling Element Bearing Analysis Measurement) are also supported. The 128240‑01 rear card provides external I/O termination—enabling easy field wiring via connectors—plus dual 4–20 mA loops and alarm relay outputs. The module is hot‑swappable, making it ideal for high‑availability systems.
