Genuine Bently Nevada 3500/33 149986-01 16-Channel Relay Module | 3500 Series – Verified Source
The Bently Nevada 3500/33 149986-01 is a critical 16-channel relay output module within the industry-standard 3500 Series machinery protection system — a platform trusted by power generation, oil & gas, and petrochemical facilities worldwide for continuous turbomachinery monitoring. Due to its essential role in safety-critical applications and its position as an end-of-life or allocation-constrained component, the 3500/33 149986-01 is frequently counterfeited or misrepresented as refurbished-to-new in the secondary market. Purchasing from unverified sources carries significant risk: substandard relay contacts, incorrect firmware revisions, and missing calibration data can lead to false trips, missed alarms, or catastrophic equipment failure.
Konmask sources the 3500/33 149986-01 exclusively through verified industrial distribution channels and direct factory-authorized partners. Every unit we supply is inspected against Bently Nevada’s original engineering specifications before shipment. We embed genuine, verified, and authentic sourcing practices into every transaction — not as marketing language, but as an operational standard backed by documentation you can review before you buy.

Our 4-Step Quality Verification Process
- Step 1 — Source Authentication: We verify the supply chain origin of every unit, confirming factory lot codes, date codes, and authorized distributor documentation before the module enters our inventory. Units without traceable provenance are rejected outright.
- Step 2 — Physical & Visual Inspection: Each module undergoes a detailed visual inspection: PCB markings, relay brand and date codes, connector integrity, label authenticity, and housing condition are checked against known-good reference units. Counterfeit indicators (mismatched fonts, incorrect silkscreen, re-marked ICs) result in immediate rejection.
- Step 3 — Functional Bench Test: Modules are powered in a 3500 rack test environment. All 16 relay channels are cycled and contact resistance is measured. Alarm and trip relay logic is verified against the 3500/33 specification. Results are logged and available as a Test Report upon request.
- Step 4 — Documentation Package: Every shipment is accompanied by a Certificate of Conformance (COC), Packing List, Country of Origin (COO) Declaration, and optional photographic inspection record. Test Reports are available for orders requiring ITP (Inspection and Test Plan) compliance.
Key Features & Benefits
- 16 Independent SPDT Relay Outputs: Provides flexible alarm and trip signal routing for complex protection logic without external relay panels, reducing wiring complexity and failure points.
- Seamless 3500 Rack Integration: Hot-swap capable within the 3500 rack architecture, enabling module replacement without full system shutdown — critical for continuous-process facilities per ISA-18.2 alarm management standards.
- SIL 2 System-Level Capability: When integrated within a certified 3500 system configuration, supports Safety Integrity Level 2 applications in accordance with IEC 61511 functional safety requirements for the process industry.
- High Contact Reliability: Gold-flashed relay contacts rated for low-level signal switching, minimizing contact resistance drift over service life — essential for 4–20 mA and dry-contact alarm circuits.
- Configurable via System Monitor: Relay assignments, latching behavior, and voting logic are fully configurable through the Bently Nevada System Monitor software without hardware modification.
- Long Service Life Design: Designed to IEC 60068 environmental stress standards, ensuring reliable operation in the vibration, temperature cycling, and humidity conditions typical of turbomachinery enclosures.
Typical Applications
- Gas Turbine Protection: Relay output for overspeed, high vibration, and high temperature trip signals on industrial gas turbines in power generation and compression stations.
- Steam Turbine Monitoring: Alarm and trip relay routing for axial position, differential expansion, and eccentricity channels on steam turbines in combined-cycle power plants.
- Centrifugal Compressor Safety: Surge detection and high-vibration trip relay outputs for centrifugal compressors in LNG, refinery, and gas processing facilities.
- Pump & Motor Protection: Relay signaling for high-vibration and bearing temperature alarms on large rotating machinery in water treatment and chemical processing plants.
- Offshore Platform Machinery: Relay output module for topside rotating equipment protection systems where SIL-rated safety instrumented systems (SIS) are required per IEC 61511.
- Petrochemical Plant DCS Integration: Hardwired relay interface between the 3500 machinery protection system and plant DCS/SCADA for alarm annunciation and ESD system integration.
