Bently Nevada 3500/33 16-Channel Relay Output Module
Manufacturer: Bently Nevada
Product Number: 3500/33
Category: 16-Channel Relay Output Module
Number of Channels: 16
Series: Bently 3500 Machinery Monitoring System
Application: Provides independent user-programmable relay outputs for critical machinery protection interfacing with vibration, speed, and temperature monitors
Product Description
The Bently Nevada 3500/33 is a full-height relay output module designed for Bently’s 3500 Machinery Monitoring System, providing 16 independent, user-programmable relay outputs for critical machinery protection. It interfaces with vibration, speed, and temperature monitors (e.g., 3500/42M, 3500/53) to trigger alarms, shutdowns, or control actions based on configurable logic (AND/OR). The module ensures reliable operation in harsh industrial environments, supporting applications in power generation, petrochemical, and manufacturing sectors.
Technical Parameters
| Parameter | Specification |
|---|---|
| Model | 3500/33 |
| Channels | 16 (SPDT relays, 250VAC/30VDC, 5A) |
| Relay Life | 100,000 operations |
| Power Supply | Derived from 3500 rack (e.g., 3500/15) |
| Power Consumption | 5.8W (typical) |
| Logic Programming | AND/OR voting for alarm tripping |
| Mounting | Insertable into 3500 rack’s right-hand slots |
| Weight | 1.2 kg (2.65 lbs) |
| Operating Temperature | -30°C to +65°C |
Advantages and Features
- Flexible Logic Configuration: Each relay can be programmed independently to execute AND/OR logic across multiple monitor channels, enabling complex safety interlocks.
- High Reliability: Epoxy-sealed design resists vibration, dust, and EMI/RFI interference, ensuring long-term performance in extreme conditions.
- Redundancy Support: Works with redundant power supplies (e.g., 3500/15) and monitors for SIL-rated safety systems.
- Rapid Response: ≤1-second alarm activation minimizes downtime risks.
Case Study: A petrochemical plant reduced compressor failures by 30% using the 3500/33 to trigger shutdowns when dual vibration monitors exceeded thresholds.
Application Fields and Case Studies
Industries:
- Power generation, petrochemicals, manufacturing, and marine systems.
Typical applications:
Case Study: A U.S. power plant improved generator reliability by 25% by using the module to activate cooling system shutdowns during excessive vibration events.
Competitive Comparison
The Bently Nevada 3500/33 outperforms alternatives with:
- Higher Channel Density: 16 channels vs. 8–12 in most comparable modules.
- Dual-Mode Logic: Configurable AND/OR voting for enhanced safety.
- Space-Saving Design: Full-height form factor maximizes rack space efficiency.
Selection Recommendations
- Multi-Channel Needs: Choose this module for applications requiring 16 independent relay outputs or complex voting logic.
- System Compatibility: Ensure compatibility with 3500 racks, power supplies (e.g., 3500/15), and monitor modules (e.g., 3500/42M).
- Safety-Critical Systems: Pair with redundant power and monitors for SIL-rated protection.
Precautions
- Configuration: Use Bently’s 3500 Rack Configuration Software to program relay logic.
- Power Stability: Deploy redundant power supplies (e.g., 3500/15) to avoid single-point failures.
- Maintenance: Regularly inspect relay contacts for wear and clean dust from vents.
