Product Overview & Description
The 3500/42M 140734‑02 + 140471‑01 module is a sophisticated two-card solution engineered for rack-mounted machinery health monitoring. The front card (140734‑02) provides comprehensive signal conditioning—accommodating proximity, seismic, velocity, and acceleration inputs to measure radial vibration, axial displacement, eccentricity, shaft absolute position, REBAM diagnostics, and circular acceptance analysis. The rear card (140471‑01) introduces dedicated tachometer (speed) I/O, enabling precise rotational velocity tracking. Together, they deliver high-resolution multi-domain monitoring—ideal for critical rotating equipment. Hot-swap capability ensures maintenance without system interruption.

Applications
This module excels in providing robust, real‑time condition monitoring for rotating machinery—from turbines and compressors to pumps and gearboxes. It supports multi-domain diagnostics (displacement, vibration, velocity, acceleration, and speed), enabling early detection of misalignment, imbalance, shaft resonance, or bearing wear. The tachometer output supports speed synchronization for data correlation and diagnostics. Its hot-swap design and output versatility make it a solid choice for integration into control systems, condition‑monitoring platforms, and predictive‑maintenance schemes.
Advantages
-
All-in-one monitoring: Monitors vibration, displacement, shaft velocity, and structural behavior within one cohesive module.
-
High-quality outputs: Buffered analog and 4–20 mA loops ensure reliable data feeds; dedicated tachometer channel enables accurate speed feedback.
-
