Bently Nevada 3500/32 149986-02+125720-02 4 Channel Relay Module

Product Introduction

The Bently Nevada 3500/32 149986-02+125720-02 4 Channel Relay Module is a high-performance, industrial-grade module designed for critical machinery protection and condition monitoring systems. As part of the 3500 series, it provides four independent relay outputs, allowing seamless communication between monitoring systems and external alarm, trip, or control mechanisms.

The module ensures precise relay actuation with minimal latency, making it suitable for applications requiring rapid protective actions. With robust channel isolation, it minimizes interference between channels and guarantees operational reliability in high-demand industrial environments, including power plants, oil and gas facilities, and heavy manufacturing industries.

The 3500/32 module also integrates diagnostic feedback via LED indicators, giving operators clear insight into relay status and helping maintain system integrity. Its modular plug-in design allows easy replacement or expansion within standard 3500 series racks.

Product Specifications

Applications

• Machinery Protection Systems: Delivers rapid relay responses for trip and alarm signals in critical rotating equipment.

• Condition Monitoring: Interfaces with 3500 series vibration, proximity, and process modules to execute control or alarm actions on abnormal events.

• Safety Interlocks: Acts as a reliable connection between monitoring systems and plant safety shutdown mechanisms.

• Process Automation: Allows integration with DCS and PLC systems for automated operational responses.

• Redundant System Configurations: Supports dual-channel redundancy for critical fail-safe applications.

Advantages

• High Reliability: Accurate relay actuation minimizes false trips or missed events.

• Modular Plug-in Design: Enables fast installation and replacement in 3500 series racks, reducing downtime.

• Channel Isolation: Four independent relay channels prevent cross-talk and interference.

• Fast Response: Typical switching time is less than 10 milliseconds.

• Diagnostic Feedback: LED indicators provide clear relay status and system health visibility.

• Industrial Robustness: Operates in a wide temperature range and tolerates high humidity environments.

FAQ

1. What types of signals can trigger the 3500/32 relay module?
   The module accepts analog or digital outputs from 3500 series vibration, proximity, and process monitoring modules.

2. Can the relays handle inductive loads?
   Yes, the SPDT relays can switch both resistive and inductive loads within rated limits.

3. How is isolation between relay channels maintained?
   Each channel is galvanically isolated at 1500 Vrms from other channels and from the backplane.

4. Can the relay outputs interface with PLCs directly?
   Yes, SPDT outputs are compatible with PLC digital input modules.

5. What is the typical relay response time?
   Less than 10 milliseconds under normal operating conditions.

6. How is the relay status indicated?
   Each channel features an LED to indicate energized or de-energized state.

7. Is hot-swapping supported for this module?
   No, power must be removed before module insertion or removal to prevent disturbances.

8. Can the module operate reliably in high humidity environments?
   Yes, it is designed for operation in 5%–95% non-condensing humidity.

9. What are the safe voltage and current ratings for the relay contacts?
   5 A at 250 VAC or 30 VDC per contact.

10. Does the module support redundant trip configurations?
    Yes, multiple relay channels can be configured for redundant or fail-safe trip logic.
