Description
Bently Nevada 350040M_140734-01 – 3500/40M Proximitor/Seismic Monitor with 140734-01 Rear I/O Plate
The Bently Nevada 350040M_140734-01 denotes a 3500/40M monitor paired with its matching rear I/O termination plate 140734-01. From my experience, this is the workhorse 4‑channel monitor for proximity probes and, in many cases, seismic transducers—ideal for radial vibration, thrust (axial) position, and casing velocity/acceleration. You might notice that keeping the OEM rear plate with the front module keeps shield terminations clean and makes swap‑outs much faster 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
- 4-channel machinery monitoring – Typically handles proximity probe or seismic inputs for radial vibration, thrust position, and casing vibration.
- Matched rear I/O (140734‑01) – Labeled screw terminals and earth points keep field terminations tidy and repeatable.
- Backplane integration – Powered via the rack; measurements and statuses are shared to other 3500 modules and the TDI (3500/22M).
- Alarm processing – Supports Alert/Danger thresholds and OK status so interlocks are predictable and easy to test.
- Service-friendly layout – Front plug‑in card with rear terminations, which in many cases shortens outage work.

| Dimensions & Weight | Standard 3500 single‑slot front module with matched rear plate footprint |
| Installation Method | Front plug‑in to 3500/05 chassis; land transducer wiring on the 140734‑01 rear plate; use provided shield/earth points |
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 balance‑of‑plant assets needing 4‑channel condition monitoring in a single module
- Retrofits aiming to keep probe runs intact while refreshing rack hardware
Advantages & Value
- Reliability – Proven 3500 platform with clear OK/Alarm behavior; easier to validate during loop checks.
- Compatibility – Native fit with Bently probes and the 3500 ecosystem; in many cases a direct like‑for‑like swap.
- Maintainability – Rear plate labeling keeps terminations traceable, which typically shortens outage tasks.
- Lifecycle support – Stable option coding and a 365‑day warranty reduce procurement risk for critical spares.
Installation & Maintenance
- Probe setup – Set proximity probe gaps and targets per spec; for seismic, confirm mounting orientation and torque.
- Wiring practice – Route low‑level transducer wiring away from VFD outputs/contactors; maintain shield continuity to the designated point.
- Grounding – Bond the rack using single‑point practice; use rear plate earth lugs to avoid loops.
- Commissioning – Verify OK status, Alert/Danger setpoints, and channel scaling; confirm data is visible via the 22M (System 1).
- Routine care – Re‑torque terminals during PMs, inspect insulation and probe cables, 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 types (proximity or seismic), desired channel assignments, and the rack option string, we’ll double‑check the 3500/40M + 140734‑01 pairing and ship to fit your maintenance window.
