Bently Nevada 3500/33 350033-01-00 149992-03 16-Channel Relay Module

Description

Key Technical Specifications

Product Introduction & Supply Chain Strategy

The Bently Nevada 350033-01-00 with 149992-03 terminal module provides 16 programmable relay outputs for critical machinery protection in 3500 series racks. It triggers trip logic, shutdown sequences, and external alarm enunciators during dangerous vibration or temperature thresholds.

Procuring this assembly as New Surplus lowers Total Cost of Ownership while maintaining 100% plant reliability. It eliminates the catastrophic failure risks of aged internal components found in pre-owned cards, securing your critical buffer stock without paying OEM lead times.

Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)

1. Perform Lock-Out/Tag-Out (LOTO) procedures on the affected machinery trip outputs before touching physical connections.
2. Put on a grounded anti-static wrist strap connected to the rack frame to prevent ESD damage.
3. Photograph the existing rear terminal wiring harness on the 149992-03 module to verify pin numbers against your wiring schematic.
4. Record any jumper positions or hardware configurations present on the existing card.

Stage 2: Removal

1. Unplug the 16-channel terminal wiring blocks from the rear 149992-03 module.
2. Loosen the top and bottom thumbscrews on the front 350033-01-00 module and rear terminal card using a flathead screwdriver.
3. Pull the module release levers outward simultaneously to disengage the backplane connectors.
4. Slide the old front module and rear terminal module straight out of the 3500 rack guide rails without twisting, avoiding backplane pin deformation.

Stage 3: Installation (Clone & Seat)

1. Verify hardware jumpers on the new 350033-01-00 match the original module configuration.
2. Align the new 149992-03 rear terminal module with the rear slot guide rails and push until seated; tighten rear thumbscrews to 0.6 N·m.
3. Align the 350033-01-00 main module with the corresponding front rack slot guide rails.
4. Firmly push the module inward until the edge connectors engage the backplane, then lock the release levers and tighten the front thumbscrews.
5. Reattach the terminal block connectors to the 149992-03 card.

Stage 4: Power-On & Testing

1. Measure the 24 V DC auxiliary terminal rails to confirm proper supply voltage without shorts.
2. Observe the front panel LEDs: OK LED should turn solid green within 10 seconds post-boot.
3. Connect via Bently Nevada 3500 System Configuration Software to confirm the rack identifies the module with zero system events/errors.
4. Perform a controlled relay output test on non-critical channels to verify contact closure response times.

Firmware/Software Versions & Upgrade Notes

• Recommended Firmware: Firmware Version 1.20 or higher is recommended for the 3500/33 relay module.
• System Software Compatibility: Requires Bently Nevada 3500 System Configuration Software Version 5.30 or higher for full 16-channel trip logic mapping.
• Compatibility Considerations: The 3500/33 16-Channel Relay Module requires a 3500/22M Rack Interface Module (RIM) running firmware Version 3.00 or later.
• Hardware Swap Warning: Never attempt firmware updates during a live machinery trip loop swap. Always flash firmware in an off-line test rack or confirm factory firmware revision parity prior to installation to avoid logic communication timeouts.

Frequently Asked Questions (FAQ)

Why is this New Surplus module cheaper than buying directly from the OEM?

This product is genuine OEM inventory sourced from cancelled global projects, plant expansion surplus, and authorized distributor overstock. Because we bypass traditional manufacturer distribution markups, we can supply authentic Bently Nevada units at 20–30% below factory list price while delivering immediate off-the-shelf dispatch.

Are these components genuinely brand new and uninstalled?

Yes. This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules reside in original factory ESD packaging, opened only for controlled incoming quality verification (serial verification and visual contact pin inspection).

What are the operational risks of buying refurbished or pulled 3500/33 relay modules?

Pre-owned or repaired relay cards carry hidden thermal fatigue on PCB traces and contact pitting on internal SPDT relays. An unrecorded relay contact failure can prevent an emergency trip signal from reaching a breaker during an over-speed or high-vibration event, leading to catastrophic turbine damage. Saving a few hundred dollars on a used module exposes your facility to tens of thousands of dollars in unplanned downtime.

Can I hot-swap the 350033-01-00 module while the plant is online?

Yes, the Bently Nevada 3500 rack architecture supports hot-swapping under power. However, pulling or inserting a 3500/33 relay card will temporarily alter the relay state depending on whether the outputs are configured as Normally Energized or Normally De-energized. You must bypass upstream trip interlocks before extracting the module to prevent unintended unit trips.

Does replacing this card require re-uploading the 3500 rack configuration?

If replacing an identical 3500/33 module with the same slot location and firmware revision, the 3500/22M Rack Interface Module automatically downloads the stored rack configuration to the new relay card upon boot. However, we advise verifying the channel logic mapping via 3500 Configuration Software post-replacement.

What warranty and authenticity documentation do you provide?

Every 350033-01-00 / 149992-03 assembly comes with a full 1-year replacement warranty, a Certificate of Quality Conformance, verifiable OEM serial numbers, and an anti-static inspection sign-off sheet.
