Product Overview & Description
The 3500/40M 176449‑01 + 126615‑01 is a four‑channel proximitor (proximity) monitor module designed for accurate, continuous monitoring of rotating machinery. The module houses four independent signal-conditioned channels for proximity sensor inputs, enabling measurement of radial vibration, thrust (axial) position, differential expansion, eccentricity, and specialized diagnostics such as REBAM (Rolling Element Bearing Analysis Measurement). The 126615‑01 indicates a particular termination and I/O interface variant—this version includes internal isolation and field‑wiring termination to simplify installation and maintain signal integrity within a standard rack enclosure.
It belongs to a rugged, industry‑hardened rack‑mount series. The module is hot‑swappable, meaning it can be seated or removed from a powered rack without shutting down the system—a major plus for uptime-focused operations.

Applications
This module is ideal for:
-
Continuous, real‑time monitoring of critical rotating machinery—turbines, compressors, pumps.
-
Capturing radial vibration, axial (thrust) position, shaft misalignment, differential thermal expansion.
-
Early detection of bearing faults using REBAM diagnostics derived from high‑resolution proximity data.
-
Environments demanding high availability: the hot‑swap capability enables servicing without system downtime.
-
Integration into condition‑monitoring systems or supervisory control—via buffered outputs, 4‑20 mA channels, or digital communications.
-
Industrial or hazardous zones, thanks to a robust design suited for reliability under chemical, thermal, or EMI stress.
Advantages
-
Multi‑function capability: Monitors a variety of parameters (vibration, thrust, expansion, eccentricity, bearing diagnostics) simultaneously.
-
High accuracy & stability: Delivers reliable measurements over time with tight accuracy specifications.
-
Hot‑swappable design: Maintenance can be performed without a rack power‑down—minimizing downtime.
-
Simplified wiring: The integral I/O termination module (126615‑01 variant) streamlines field wiring and improves signal routing.
-
Modular system: Compatible with existing rack environments and scalable for large machine‑monitoring systems.
-
Diagnostic flexibility: Provides both analog outputs and digital interface options, facilitating broad integration possibilities.
-
Rugged and reliable: Engineered for harsh industrial conditions, with appropriate isolation, thermal resistance, and interference rejection.
