Bently Nevada 350040M_176449-01 – 3500/40M Proximitor/Seismic Monitor with 176449-01 Rear I/O Plate

The Bently Nevada 350040M_176449-01 pairs the 3500/40M four-channel monitor with its matching rear termination plate 176449-01. From my experience, this is the workhorse card for proximity probes and seismic transducers—great 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 quicker 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 machinery monitoring – Typically supports proximity probes and seismic sensors for radial vibration, thrust position, and casing vibration.
• Matched rear I/O (176449‑01) – Clearly labeled screw terminals and earth points keep field terminations tidy and traceable.
• Integrated alarm processing – Configurable Alert/Danger thresholds and OK status so testing is predictable.
• Backplane integration – Powered via the rack, with data shared to the TDI (3500/22M) and relay modules over the 3500 backplane.
• Service‑friendly layout – Front plug‑in card with rear terminations, which in many cases shortens outage work.

Technical Specifications

Specs reflect common characteristics for a 3500/40M paired with the 176449‑01 rear plate. If you share your transducer models and rack option string, we’ll verify an 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 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.
• Risk reduction – A 365‑day warranty and stable lead times support critical spares planning.

Installation & Maintenance

• Probe setup – Set proximity probe gaps/targets per spec; for seismic sensors, confirm orientation and mounting torque.
• Wiring discipline – 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 flow via the 22M into System 1.
• Routine care – Re‑torque terminals during PMs, inspect probe cables and 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 transducer types (proximity or seismic), channel assignments, and rack option string, we’ll double‑check the 3500/40M + 176449‑01 pairing and ship to fit your maintenance window.
