BENTLY NEVADA 3500/33 16-Channel Relay Module
1. Product Description
The BENTLY NEVADA 3500/33 is a full-height 16-channel relay module designed for machinery protection and vibration monitoring systems. As part of the 3500 Series, it integrates with BENTLY’s modular racks to provide configurable alarm outputs, enabling precise control over critical rotating equipment such as turbines, compressors, and generators. The 3500/33 supports customizable voting logic for each relay, allowing users to define alarm conditions based on monitored parameters like vibration amplitude, speed, or temperature. Its epoxy-sealed construction and EMI-resistant design ensure reliable performance in harsh industrial environments, while front-panel LEDs provide real-time status feedback.

3. Advantages and Features
- High Channel Density: 16 independent relays reduce rack space compared to single-channel alternatives.
- Programmable Logic: Customizable AND/OR logic for alarm activation, enhancing flexibility in fault response.
- Robust Design: Epoxy-sealed housing protects against moisture, dust, and shocks, extending lifespan by 20% in corrosive environments.
- Hot-Swap Capability: Modules can be replaced without powering down the system, minimizing downtime.
- Low Power Consumption: 5.8 W operation reduces energy costs in large-scale installations.
4. Application Areas and Use Cases
Industry Applications:
Industry Applications:
- Energy: Power plants, oil refineries, and gas pipelines.
- Manufacturing: Industrial machinery and rotating equipment.
- Transportation: Marine propulsion systems.
Case Study: A European steel mill reduced unplanned downtime by 25% using the 3500/33 to trigger automatic shutdowns during excessive vibration events, preventing $500,000 in equipment damage annually.
5. Competitor Comparison
- Higher Channel Capacity: 16 channels vs. typical 8–12 channels in comparable modules.
- Enhanced EMI Resistance: Meets CE standards without additional shielding, reducing installation complexity.
- Longer Relay Lifespan: 100,000 cycles vs. 50,000–70,000 cycles in competing products.

6. Selection Recommendations
- Channel Requirements: Choose the 3500/33 for systems needing 16+ relay outputs; consider the 3500/32 for fewer channels.
- Safety Compliance: Ensure compatibility with API 670 standards for machinery protection systems.
- Expandability: Pair with 3500/22M transient modules for comprehensive vibration analysis.
7. Precautions
- Software Compatibility: Use 3500 Rack Configuration Software v3.3+ for programming.
- Power Management: Verify 24 VDC supply stability to avoid relay misoperation.
- Installation: Mount in well-ventilated areas to prevent overheating in high-temperature environments.
