Bently Nevada 350042M-140734-02 – 3500/42M Proximitor/Seismic Monitor with 140734-02 Rear I/O Plate

The 350042M_140734-02 combines the Bently Nevada 3500/42M four-channel monitor with its matching rear termination plate 140734‑02. From my experience, the 42M is the everyday workhorse for proximity probes and seismic sensors—radial vibration, thrust (axial) position, and casing velocity/acceleration all in one module. You might notice that sticking with the revision‑matched rear plate keeps shield terminations tidy and, in many cases, turns a swap into a straightforward plug‑in job.

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, and casing vibration.
• Matched rear I/O (140734‑02) – Clearly labeled screw terminals and earth points keep wiring consistent and easy to audit.
• On-board alarm logic – Alert/Danger thresholds with OK status tracking so interlocks are predictable and testable.
• Backplane integration – Powered by the rack; all measurements and statuses share cleanly to the TDI and relay modules.
• Service-friendly design – Front plug‑in module with rear terminations shortens outage work and reduces wiring mix‑ups.

Technical Specifications

Specs reflect what you typically see on a 3500/42M paired with the 140734‑02 rear plate. 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 keeping existing probe runs 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 direct like‑for‑like swap.
• Maintenance efficiency – Clear rear labeling and shield points speed up terminations and future troubleshooting.
• Procurement confidence – Stable option coding plus a 365‑day warranty typically reduces project risk.

Installation & Maintenance

• Probe setup – Set proximity gaps/targets per spec; for seismic sensors verify mount orientation and torque.
• Wiring practice – Keep low‑level transducer wiring away from VFD outputs and contactor bundles; maintain shield continuity to the designated point.
• Grounding – Bond the rack using single‑point practice; use the rear plate earth lugs to avoid loops.
• Commissioning – Check OK status, scale factors, and Alert/Danger setpoints; confirm 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

If you share your probe models (proximity or seismic), channel assignments, and rack option string, we’ll validate the 3500/42M + 140734‑02 match and line up a shipment that fits your maintenance window.
