Product Description
TheBently Nevada 3500-15is a5A Relay Moduledesigned for machinery protection systems,providing critical alarm and shutdown functions in the Bently Nevada 3500 monitoring system.This relay module offers two independent Form C relay outputs(2A rating)for connecting to external safety systems.Engineered for high-reliability applications in critical machinery protection,it ensures safe operation of turbines,compressors,and other rotating equipment.
Application Scenarios
In a natural gas compressor station,theBently Nevada 3500-15relay module monitors vibration levels on a critical centrifugal compressor.When vibration exceeds predefined alarm thresholds,the3500-15activates its relay outputs to trigger warning alarms in the control room.If vibrations reach dangerous levels,the second relay initiates an emergency shutdown,preventing catastrophic equipment failure that could result in millions of dollars in damage and weeks of production downtime.

Technical Principles and Innovative Values
Dual Independent Relays:TheBently Nevada 3500-15provides two completely isolated Form C relays,allowing for separate alarm and shutdown functions with independent circuitry for enhanced reliability
Fast Response Time:With response times under 10 milliseconds,the module ensures rapid reaction to critical machinery conditions,minimizing potential damage during fault conditions
SIL 2 Capability:Designed to meet Safety Integrity Level 2 requirements,making it suitable for safety-critical applications in process industries
Application Cases and Industry Value
A power generation facility using gas turbines implemented theBently Nevada 3500-15relay modules across their turbine protection systems.During an unexpected blade failure incident,the3500-15modules detected abnormal vibrations and initiated a controlled shutdown within milliseconds,preventing secondary damage to the turbine casing and bearings.The rapid response saved an estimated$3.5 million in repair costs and reduced downtime from potential months to just three weeks for scheduled maintenance and repair.
