Bently Nevada 350042M-176449-02 – 3500/42M Proximitor/Seismic Monitor with 176449-02 Rear I/O Plate

The Bently Nevada 350042M_176449-02 pairs a 3500/42M four-channel monitor with its matching rear termination plate 176449‑02. From my experience, this is the dependable choice for proximity probe and seismic measurements on rotating machinery—radial vibration, thrust (axial) position, and casing velocity or acceleration are all covered. You might notice that using the revision‑matched rear plate keeps shield terminations clean and, in many cases, turns a swap into a straightforward plug‑in job during a turnaround.

Company’s Order Placement Process and Guarantees

• Warranty period: 365 days
• Delivery time: 1 week for in-stock; no more than 1 month at the latest
• Payment method: 50% advance payment; full payment for delivery
• Express delivery methods: FedEx, UPS, DHL

Key Features

• Four-channel monitoring – Typically accepts proximity probe drivers and seismic transducers for radial vibration, thrust position, and casing vibration.
• Matched rear I/O (176449‑02) – Clearly labeled screw terminals and earth points keep field terminations tidy and traceable.
• Alarm processing – Configurable Alert/Danger thresholds with OK status so interlocks are predictable and easy to test.
• Backplane integration – Powered via the 3500 rack; measurements are shared internally to relays and the 3500/22M TDI.
• Service‑friendly layout – Front plug‑in module with rear terminations usually shortens outage tasks and reduces wiring errors.

Technical Specifications

Figures below reflect what you typically see on a 3500/42M paired with rear I/O 176449‑02. Share your probe types and rack option string and we’ll confirm the exact fit before shipment.

Application Fields

• Compressors and turbines monitoring radial vibration, thrust position, and casing vibration
• Large motors, pumps, and fans where continuous vibration trending supports protection and reliability
• Gearboxes and critical balance‑of‑plant assets needing 4‑channel coverage in a single card
• Retrofits that keep probe runs intact while refreshing rack hardware

Advantages & Value

• Reliability – Predictable OK/Alert/Danger behavior; easier to validate during loop checks.
• Compatibility – Native fit with the 3500 ecosystem and Bently probes; in many cases a like‑for‑like replacement.
• Maintenance efficiency – Rear labeling and shield points help technicians move faster and reduce wiring mistakes.
• Risk control – Stable option coding with a 365‑day warranty tends to de‑risk shutdown planning.

Installation & Maintenance

• Probe setup – Set proximity gaps/targets per spec; for seismic sensors, verify orientation and mounting torque.
• Wiring practice – Keep low‑level transducer wiring away from VFD outputs/contactors; maintain shield continuity at the designated point.
• Grounding – Bond the rack using single‑point practice; use the rear plate earth lugs to avoid loops.
• Commissioning – Confirm OK status, scale factors, and Alert/Danger setpoints; check data visibility through the 22M into System 1.
• Routine care – Re‑torque terminals during PMs, inspect probe cables/insulation, and review trend/OK logs for early warnings.

Quality & Certifications

• CE and RoHS compliance (typical for Bently Nevada 3500 components)
• UL/cUL suitability for industrial control panels, model dependent
• Manufacturer’s warranty: 12 months from shipment

Quick field note: “Channels gapped, OKs came right up, and the swap was done in one window.” If you share your probe types, channel assignments, and rack option string, we’ll validate the 3500/42M + 176449‑02 pairing and line up a fast shipment.
