3500/40 176449-01 dual-channel velocity and vibration monitor module

BENTLY 3500/40 (with part number 176449-01) is a dual-channel velocity and vibration monitor module developed by Bently Nevada, specifically designed for the 3500 Series Machinery Protection System. It is tailored to monitor velocity-based vibration (e.g., bearing housing vibration) and acceleration signals of rotating machinery (such as motors, pumps, fans, and small turbines), providing real-time fault alerts and protection actions to prevent mechanical failures. As a core monitoring component in mid-to-low speed rotating equipment applications, it integrates high-precision signal processing, flexible alarm configuration, and seamless integration with the 3500 system, ensuring reliable operation in industrial environments. The detailed information is as follows:

1. Basic Overview

Category	Details
Product Type	Dual-channel velocity/vibration monitor module (for 3500 Series Machinery Protection System)
Model & Part Number	- Model: 3500/40 - Part Number: 176449-01 (unique identifier for procurement, compatibility verification, and after-sales service)
Form Factor	Half-height module – fits into a single slot of the 3500 system frame (compatible with 3500/05, 3500/10, and 3500/20 frames)
Dimensions	127 mm (height) × 50.8 mm (width) × 120.7 mm (depth) – conforms to the 3500 series module size standard

Power Supply	Derived from the 3500 frame backplane: 24 VDC (typical current draw: 0.3 A; maximum: 0.5 A)
Operating Temperature Range	-40°C to +70°C – suitable for harsh industrial environments (e.g., factory workshops, pump rooms, turbine enclosures)
Certifications	CE (compliant with EU EMC Directive 2014/30/EU), UL 508 (industrial control equipment safety standard), IEC 61000-6-2 (industrial EMC immunity)

2.4 Output Interfaces (Alarms & Data Transmission)

Relay Outputs: 2 Form-C relays (1 normally open, 1 normally closed) – rated 250 V AC / 5 A, 30 V DC / 5 A. Each relay can be mapped to either channel’s alarm status (e.g., Relay 1 = Channel 1 Danger, Relay 2 = Channel 2 Danger) for direct control of external equipment (e.g., motor contactors, alarm buzzers).
Analog Outputs: 2 configurable 4–20 mA analog outputs (1 per channel) – transmits real-time vibration amplitude data (e.g., 4 mA = 0 mm/s, 20 mA = 50 mm/s) to recorders, HMIs, or DCS systems for trend monitoring.
Backplane Communication: Connects to the 3500 frame backplane – transmits raw vibration data, alarm status, and module health information to the 3500/92 communication gateway (for upper-level system integration).

3. Functional Features

3.1 Flexible Configuration & Diagnostics

Configuration Methods:
1. Local Configuration: Via the 3500 frame’s front-panel display (3500/05 frame) or a connected laptop (using Bently Nevada’s "3500 Configuration Software") – adjusts thresholds, filters, and output mappings without module removal.
2. Remote Configuration: Via upper-level software (e.g., Bently System 1, DCS) through the 3500/92 gateway – supports batch configuration of multiple 3500/40 modules in large-scale systems (e.g., a factory with 20+ motor monitoring points).
Self-Diagnosis: Monitors internal hardware (power supply, ADC circuits, relay contacts) and sensor connections (open-circuit, short-circuit detection) – triggers a "Module Fault" alert if anomalies are detected (e.g., sensor cable breakage), enabling proactive maintenance.

3.2 Data Logging & Trend Analysis

Event Logging: Stores up to 500 historical alarm events per channel, including timestamp (millisecond precision), alarm type (Alert/Danger), and vibration amplitude at alarm trigger – supports post-fault root-cause analysis (e.g., identifying whether vibration spikes were caused by load changes or component failure).
Waveform Capture: Optional raw waveform recording (1–10 seconds per capture) – triggered manually or automatically by danger alarms, capturing transient vibration signals (e.g., gearbox failure shocks) for detailed frequency analysis via Bently System 1 software.
