Bently Nevada 3500/32-01-01-00 Relay Module

This relay module provides four independent relay outputs for Bently Nevada 3500 machinery protection systems. It activates alarms and shutdowns when monitored parameters exceed programmed Alert or Danger setpoints. The module offers flexible configuration for various protection schemes and annunciation requirements.

Output Configuration and Relay Types

The Bently Nevada 3500/32-01-01-00 contains four independent relay outputs, each field-configurable as normally energized or normally de-energized. You can assign any relay to respond to a single monitored parameter or a logical combination of conditions. The module supports latch/non-latch, alarm multiply, and sequence-of-events monitoring for comprehensive trip and alarm strategies. It includes an optional manual reset pushbutton and a trip-multiply function for sequencing.

Technical Specifications

Alarm Logic and Diagnostic Features

The module supports logical AND/OR conditions, enabling complex shutdown logic based on multiple parameters . You can assign relays to respond to Alert or Danger conditions, or to system status conditions like OK status . The module performs continuous diagnostic self-checks, verifying coil health and contact operation . A front-panel LED indicates the module’s health, bypass status, and the state of each relay . The trip-multiply function enables event-based sequential shutdowns controlled by other modules .

System Integration and Application Use

This module forms the final output stage of the 3500 protection system, acting on decisions from the monitor modules . It integrates seamlessly with PLCs, shutdown systems, and annunciator panels in the plant . The module’s 4 relays provide scalable protection for turbines, compressors, and pumps. Its normally energized configuration ensures failsafe operation, de-energizing the relays upon power loss . The module’s reliable construction ensures long-term performance in demanding environments .
