Bently Nevada 3500/32 4-Channel Relay Output Module
Manufacturer: Bently Nevada
Product Number: 3500/32
Category: 4-Channel Relay Output Module
Number of Channels: 4
Series: 3500 Machinery Monitoring System
Application: Critical machinery protection triggering alarms, shutdowns, and annunciation
Function: Provides four independent, user-programmable relay outputs
Product Description
The Bently Nevada 3500/32 is a compact, full-height relay output module designed for the 3500 Machinery Monitoring System. It provides four independent, user-programmable relay outputs for critical machinery protection, triggering alarms, shutdowns, or control actions based on configurable logic (AND/OR). Ideal for harsh industrial environments, the module supports applications in power generation, petrochemical, and manufacturing sectors, ensuring reliable operation and reduced downtime.
Technical Parameters
| Parameter | Specification |
|---|---|
| Model | 3500/32 |
| Channels | 4 (SPDT relays, 250VAC/30VDC, 5A) |
| Relay Life | 100,000 operations |
| Power Supply | Derived from 3500 rack (e.g., 3500/15) |
| Power Consumption | 3.5W (typical) |
| Logic Programming | AND/OR voting for alarm tripping |
| Mounting | Insertable into 3500 rack’s right-hand slots |
| Weight | 0.8 kg (1.76 lbs) |
| Operating Temperature | -30°C to +65°C |
Advantages and Features
- Flexible Logic Configuration: Each relay can execute AND/OR logic across multiple monitor channels, enabling customized safety interlocks.
- Space-Saving Design: Four channels in a single module optimize rack space compared to 8–12-channel alternatives.
- High Reliability: Epoxy-sealed construction resists vibration, dust, and EMI/RFI interference.
- Safety Compliance: Supports SIL 2-rated systems and hazardous area certifications (e.g., ATEX/IECEx) with voltage restrictions.
Case Study: A U.S. power plant reduced generator downtime by 20% using the 3500/32 to trigger cooling system shutdowns during excessive vibration events.
Application Fields and Case Studies
Industries:
- Power generation, petrochemicals, manufacturing, and marine systems.
typical application:
Case Study: A petrochemical plant minimized compressor failures by 25% by programming the module to activate shutdowns when dual vibration monitors exceeded thresholds.
Competitive Comparison
The Bently Nevada 3500/32 outperforms alternatives with:
- Higher Channel Density: Four channels in a compact form factor.
- Dual-Mode Logic: Configurable voting for enhanced safety.
- Certifications: Built-in support for SIL and hazardous area standards.
Selection Recommendations
- Small-Scale Needs: Choose this module for applications requiring up to four relay outputs.
- System Compatibility: Ensure compatibility with 3500 racks and monitor modules (e.g., 3500/42M).
- Safety-Critical Systems: Opt for redundant power supplies (e.g., 3500/15) and verify voltage compliance for SIL-rated installations.
Precautions
- Voltage Limitations: For hazardous area or SIL applications, use voltages ≤250VAC/30VDC to comply with certifications.
- Configuration: Use Bently’s 3500 Rack Configuration Software to program relay logic.
- Maintenance: Regularly inspect relay contacts and ensure proper ventilation.
