Product Overview & Description
The 3500/42 176449‑02 + 128229‑01 module constitutes a dual‑card system in a rack‑mounted rotating-machine protection platform. The front card (176449‑02) offers high‑precision signal conditioning from proximity, velocity, or acceleration sensors, enabling monitoring of radial vibration, axial displacement, shaft expansion, eccentricity, speed (via processed signals), and diagnostic modes like REBAM. The rear card (128229‑01) provides internal I/O termination for field wiring, dual 4–20 mA loop outputs per channel, and relay‑based alarm signals. The module is designed for hot‑swappable replacement, allowing maintenance without interrupting operation—ideal for critical/high‑uptime applications.

Applications
Perfect for high‑reliability environments, this module supports real‑time condition monitoring of rotating machinery—turbines, generators, pumps, compressors. Its wide range of supported sensor types allows it to detect imbalance, misalignment, bearing degradation, or shaft movement. The internal dual 4–20 mA outputs link seamlessly into trending and recorder systems; relay outputs enable alarming. The hot‑swap capability ensures minimal downtime during maintenance, maintaining continuous protection.
