Bently Nevada 133300-01 – Rear I/O Termination for 3500 Series Monitor Channels
The Bently Nevada 133300-01 is a rear I/O termination module used on 3500 racks to land field wiring and interface it to the paired front‑side monitor card through the backplane. From my experience, this kind of rear module keeps things tidy—clear terminal labeling, repeatable channel mapping, and no need to disturb the front monitor when you’re doing maintenance. You might notice that it typically supports the same transducer families as its paired monitor (proximity, seismic, or Keyphasor), which makes loop checks straightforward.
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
- Native 3500 rack integration – Mates to the matching front monitor via the rack backplane; preserves channel order and labeling.
- Clean field terminations – Screw terminals and clear legends support faster loop checks and easier troubleshooting.
- Shielding and earth provisions – Helps maintain signal integrity for proximity probes, seismic sensors, and speed pickups.
- Service-friendly – Rear access means you can replace or re-land wires without removing the front card—usually saving time during outages.
- Passive design – No separate power; fewer active components to fail and simpler verification during PMs.
Technical Specifications
Values below reflect what is commonly associated with Bently Nevada 3500 rear I/O modules. If you share your front monitor part number and rack slot, we’ll confirm the exact pairing for 133300-01 before shipment.
| Brand / Model | Bently Nevada 133300-01 |
| HS Code | 9031.90 (Parts of measuring or checking instruments) |
| Power Requirements | None (passive rear I/O; interfaces via 3500 backplane) |
| Dimensions & Weight | Standard 3500 rear I/O form factor; fits the designated rear slot for its paired front monitor |
| Operating Temperature | Typically 0 to +65 °C when installed per 3500 rack guidelines |
| Signal Input/Output Types | Field screw terminals for proximity, seismic, or speed/keyphasor transducers (dependent on front monitor type) |
| Communication Interfaces | Backplane connection to the front 3500 monitor (no external comms on the I/O itself) |
| Installation Method | Rear rack mounting with captive screws; shield/earth termination provided on the board |
Application Fields
- Large rotating assets: turbines, compressors, and critical pumps requiring continuous vibration monitoring
- Balance‑of‑plant equipment integrated into a 3500 rack for alarms, trips, and trending
- Retrofits where keeping existing probe runs and panel wiring intact is a priority
- Units standardizing on 3500 modules to simplify spares and maintenance practices
Advantages & Value
- Reliability – Passive termination with clear labeling tends to reduce wiring mistakes and nuisance alarms.
- Compatibility – Built for the 3500 ecosystem; in most cases it’s a like‑for‑like swap with no rewiring.
- Maintenance efficiency – Rear access helps technicians work faster during outages or online inspections.
- Risk reduction – Traceable parts and a 365‑day warranty support critical‑spares programs.
Installation & Maintenance
- Rack alignment – Mount behind the correct front monitor slot; tighten captive screws evenly to seat connectors.
- Wiring discipline – Land transducer leads and shields per the wiring diagram; separate low‑level signals from high‑EMI conductors.
- Grounding – Follow single‑point grounding practice to avoid loops; use the provided shield/earth points.
- ESD handling – Treat as ESD‑sensitive hardware; use a grounded wrist strap during replacement.
- Routine checks – Re‑torque terminals, inspect insulation, and verify channel health in your monitoring software during PMs.
Quality & Certifications
- CE and RoHS compliance (typical for Bently Nevada rack components)
- UL/cUL suitability for industrial control panels, model dependent
- Manufacturer’s warranty: 12 months from shipment
Share your front monitor part number (3500/xx), rack revision, and transducer types, and we’ll verify that 133300-01 is the correct rear I/O for your slot so the changeout is quick and uneventful.
