Key Features & Benefits

• Flexible Alarm Logic: Configure each relay for Alert, Danger, or OK status from any monitor channel
• Voting Logic Support: Implement 2oo3, 1oo2, or custom voting schemes for redundant protection
• Hot-Swappable Design: Replace modules without system shutdown (with proper bypass procedures)
• LED Status Indicators: Real-time visual feedback for each relay state
• Factory Calibration: Pre-configured and tested to OEM specifications
• Proven Reliability: MTBF >150,000 hours in industrial environments

Application Scenarios

Power Generation: Steam and gas turbine protection systems requiring multi-channel alarm outputs for vibration, temperature, and position monitoring.

Oil & Gas: Compressor train shutdown logic, pump protection, and critical machinery monitoring in upstream, midstream, and downstream facilities.

Manufacturing: High-speed rotating equipment protection in paper mills, steel plants, and chemical processing facilities.

Marine & Offshore: Propulsion system monitoring and auxiliary equipment protection in harsh environmental conditions.

Integration Solutions

The 3500/33 module integrates seamlessly with Bently Nevada proximity probes, accelerometers, and transducers. Configure relay outputs to trigger:

• Emergency shutdown systems (ESD)
• Distributed control systems (DCS) alarm inputs
• Annunciator panels and SCADA interfaces
• Sequential shutdown logic for multi-stage equipment

Common Questions & Answers

Q: Can I use this module with non-Bently Nevada monitors?
A: The 3500/33 is designed exclusively for 3500 Series racks. It receives alarm status via the proprietary backplane and cannot interface directly with third-party systems.

Q: What’s the difference between 149992-01 and 149992-02?
A: The -01 version provides standard relay outputs, while the -02 variant includes failsafe relay logic for enhanced safety integrity (SIL-rated applications).

Q: How do I program relay assignments?
A: Use Bently Nevada 3500 Rack Configuration Software to assign each relay to specific monitor channels, alarm setpoints, and voting logic.

Q: Is external power required for relay operation?
A: No. The module draws power from the 3500 rack power supply. Ensure your rack has sufficient capacity (check total module power budget).

Q: Can relays be configured for latching or non-latching operation?
A: Yes. Each relay supports both latching (requires manual reset) and non-latching (auto-reset) modes via software configuration.
