The BENTLY NEVADA 3500/32 is a 4-channel solid-state relay module designed for the 3500 Machinery Monitoring System, providing independent relay outputs to trigger alarms or shutdowns based on inputs from monitor channels. It supports configurable logic (AND/OR) for multi-channel voting, ensuring precise control in critical industrial applications. The module interfaces with proximity, vibration, and temperature monitors (e.g., 3500/42M) to activate safety systems when machinery parameters exceed user-defined thresholds, safeguarding rotating equipment in power generation, petrochemical, and manufacturing sectors.

3. Advantages and Features
Flexible Logic Programming: Each relay can be independently configured for AND/OR logic, enabling complex safety interlocks.
Solid-State Reliability: No moving parts, ensuring faster response times (≤10 ms) and longer lifespan (≥100,000 operations).
Real-Time Alarm Response: Triggers based on Alert/Danger status from 3500 monitor modules (e.g., 3500/42M), reducing downtime by up to 20%.
Rugged Design: Epoxy-sealed construction withstands vibration, dust, and extreme temperatures.
Ease of Integration: Configurable via BENTLY’s 3500 Rack Configuration Software for seamless system integration.
Case Study: A European chemical plant reduced unplanned shutdowns by 15% using the 3500/32 to interlock compressor vibration monitors with emergency stop systems.
4. Application Fields and Case Studies
Industries:
Power generation, petrochemicals, manufacturing, marine, and HVAC.
Turbines, generators, compressors, pumps, and heavy machinery.
Case Study: A U.S. power plant improved generator protection by 25% using the module to activate cooling system shutdowns during excessive vibration events.
5. Competitive Comparison
The BENTLY NEVADA 3500/32 outperforms standard relay modules with:
Higher Channel Density: 4 channels vs. 2–3 in most alternatives.
Extended Temperature Range: Operates in extreme conditions (-40°C to +85°C) for offshore or high-temperature environments.
Dual-Mode Logic: Configurable AND/OR voting for enhanced safety compared to fixed-logic solutions.
6. Selection Recommendations
System Compatibility: Ensure compatibility with existing 3500 racks and monitor modules (e.g., 3500/42M).
Functionality: Opt for the 4-channel design for complex interlocks; pair with 3500/42M for comprehensive vibration monitoring.
7. Precautions
Wiring: Use shielded cables to prevent EMI interference; ground properly per BENTLY’s guidelines.
Power Stability: Ensure a filtered DC power supply to avoid voltage fluctuations.
Maintenance: Regularly verify relay operation via the 3500 Rack Configuration Software.
