A Bently Nevada Relay Output Module, such as the 3500/33 16-Channel Relay Module or the 3500/32 4-Channel Relay Module, provides alarm and shutdown capabilities from the Bently Nevada monitoring system to external plant control systems or emergency shutdown systems. They receive alarm and "Not-OK" statuses from various monitor channels within the 3500 rack and activate relays based on pre-programmed logic.

Functionality: These modules provide discrete (on/off) contacts that can be used to:

Trigger alarms (e.g., siren, light, DCS alert) when a monitored parameter (like vibration or temperature) exceeds a warning or danger setpoint.
Initiate machinery shutdown sequences to prevent catastrophic failure or further damage.
Provide status indications of the monitoring system itself (e.g., "System OK").
Key Features:
Programmable Alarm Drive Logic: Each relay can be independently programmed using AND/OR logic, allowing for complex voting schemes (e.g., 2-out-of-3 voting for redundancy) based on alert, danger, or Not-OK statuses from any monitor channel in the rack.
Multiple Relay Channels: Modules come with a fixed number of outputs, commonly 4 or 16 channels, providing flexibility for various applications.
Single-Pole Double-Throw (SPDT) Relays: This contact configuration offers versatility, allowing connections for both Normally Open (NO) and Normally Closed (NC) applications.
Epoxy-Sealed Relays: Enhances durability and provides environmental protection, crucial for industrial environments.
Arc Suppressor: Often included as standard to protect relay contacts and extend their life, especially when switching inductive loads.
LED Indicators: Front-panel LEDs provide visual status for module operation (OK, TX/RX) and individual channel alarm status, simplifying troubleshooting.
Selectable Operation: Channels can often be configured for Normally De-energized or Normally Energized operation.

Product Parameters

Specific parameters will depend on the exact module, but typical specifications for Bently Nevada Relay Output Modules include:

Number of Channels: 4, 8, or 16 independently programmable relay outputs.
Relay Type: Single-Pole, Double-Throw (SPDT) for standard modules. Triple Modular Redundancy (TMR) modules like the 3500/34 might use DPDT relays in a specific configuration for voting.
Contact Ratings:

Max Switched Voltage: Typically up to 250 Vac or 125 Vdc.
Max Switched Current: Up to 5 A (resistive load), with lower ratings for inductive loads or specific DC voltages.
Max Switched Power: E.g., 600 VA (AC resistive), 120 W (DC resistive).

Contact Life: Often rated for 100,000 cycles at full load.
Power Consumption: Relatively low, e.g., 5.8 watts typical for a 16-channel module.
Operating Temperature: Wide industrial range, typically -30°C to +65°C (-22°F to +150°F).
Storage Temperature: -40°C to +85°C (-40°F to +185°F).
Humidity: 95% non-condensing.
Physical Dimensions: Full-height modules designed to fit into Bently Nevada 3500 series racks.
Software Compatibility: Requires Bently Nevada 3500 Rack Configuration Software (specific version) for programming.

Product Advantages

Enhanced Machine Protection: Directly integrates with the highly reliable Bently Nevada 3500 monitoring system to provide critical machinery protection and emergency shutdown capabilities.
High Reliability: Designed and built for harsh industrial environments, ensuring consistent and dependable performance. Epoxy-sealed relays contribute to their robustness.
Customizable Logic: The ability to program independent voting logic for each relay output provides immense flexibility in tailoring alarm and shutdown responses to specific machinery protection philosophies.
Improved Safety: By providing reliable outputs for alarms and shutdowns, these modules help prevent catastrophic equipment failures, protect personnel, and comply with safety regulations (e.g., for SIL-rated systems with appropriate safety certification).
Clear Diagnostics: Front-panel LEDs for module and channel status aid operators and technicians in quickly diagnosing issues.
Seamless Integration: Designed to integrate flawlessly within the Bently Nevada 3500 Series rack system.
Industry Standard Compliance: Often designed to comply with critical industry standards like API 670 for machinery protection systems.

Important Considerations

System Dependence: These modules are part of the larger Bently Nevada 3500 monitoring system. They cannot function standalone and require a properly configured 3500 rack, rack interface module, and specific software versions.
Programming Complexity: While powerful, configuring the alarm drive logic requires careful planning and a thorough understanding of the 3500 Rack Configuration Software and the machinery's protection philosophy. Incorrect programming can lead to nuisance trips or, worse, failure to trip when needed.
Wiring Practices: Correct wiring and termination of the relay contacts are critical. Always adhere to Bently Nevada's detailed installation manuals, paying attention to voltage and current ratings, inductive loads, and proper arc suppression.
Safety Critical Applications: For safety-instrumented systems (SIS) or those requiring Safety Integrity Level (SIL) certification, ensure that the specific relay module model is certified for that purpose and that all installation and maintenance procedures adhere to the functional safety manual.
Maintenance and Testing: Regular testing of relay outputs and verification of alarm logic are crucial to ensure the continued integrity of the protection system. Relay contact life should also be considered in maintenance planning.
